Abstract:
SUMMARYLong-term fertilization experiment has been conducted since 1981 to study the effect of soil management practices on soil fertility, soil carbon and nitrogen sequestration, soil culturable microbe counts and crop yields at the Nanhu Experimental Station in the Hubei Academy of Agricultural Sciences (situated in the middle reach of the Yangtze River and the rice–wheat cropping system). The experiment was designed with the following eight treatments: (1) unfertilized treatment: Control; (2) inorganic nitrogen fertilizer treatment: N; (3) inorganic nitrogen plus inorganic phosphorus fertilizer treatment: NP; (4) inorganic nitrogen, inorganic phosphorus plus inorganic potassium fertilizer treatment: NPK; (5) pig dung compost (manure) treatment: M; (6) inorganic nitrogen fertilizer plus manure: NM; (7) inorganic nitrogen, inorganic phosphorus fertilizer plus manure treatment: NPM and (8) inorganic nitrogen, inorganic phosphorus, inorganic potassium fertilizer plus manure treatment: NPKM. The results showed that long-term application of organic manure in combination with inorganic fertilizer significantly (p < 0.05) increased soil organic C concentrations compared with the corresponding inorganic fertilizers alone. Soil organic C contents were significantly (p < 0.05) increased in balanced application of NPK fertilizers in comparison to unbalanced application of fertilizers. After 30 years of experiment, soil organic C and total N sequestration rate averagely were 0.48 t ha−1 year−1 and 28.3 kg ha−1 year−1 in the fertilized treatments respectively; nevertheless, it were 0.27 t ha−1 year−1 and 9.7 kg ha−1 year−1 in the unfertilized treatment. Application of organic fertilizer in combination with inorganic fertilizer significantly (p < 0.05) increased culturable microbial counts compared with the corresponding inorganic fertilizers alone. The balanced application of NPK fertilizers significantly (p < 0.05) increased culturable microbial counts compared with unbalanced application of fertilizers. The average grain yield of wheat and rice was significantly (p < 0.05) higher in organic manure combined with inorganic fertilizer treatment than in inorganic fertilizer alone and unfertilized control. Therefore, long-term application of organic manure combined with inorganic fertilizer and balanced application of NPK fertilizers could increase soil organic C and total N sequestration, culturable microbial counts and crop grain yields.

Abstract:
Rice-fish farming is a model that is considered suitable to be applied in rice fields, both on a large or limited land as long as water availability is sufficient for rice and fish to grow. In rice-fish farming, there is integration between fisheries and agriculture where integration can improve the efficiency of the supply and use of fertilizer and feed. The research aimed to find the reduction of inorganic fertilizer in integrated rice-fish farming with the rice-fish system to increase fertilizer efficiency. The experiment used a single factor randomized block design with five levels of treatment, which are; rice monoculture with 100% inorganic fertilizer, fish monoculture, rice-fish farming with 100% inorganic fertilizer, rice-fish farming with 60% inorganic fertilizer, and rice-fish farming with 20% inorganic fertilizer. Rice-fish farming could reduce the application of inorganic fertilizers through complementary relationships between rice and fish. Applying inorganic fertilizer 20% of the reference dose in the rice-fish farming produced productivity that was not significantly different from the rice-fish farming fertilized with 60% and 100% of the reference dose, and the rice monoculture with 100% of the reference dose of inorganic fertilizer. Rice-fish farming could save 80% of inorganic fertilizers so that increasing the efficiency of using inorganic fertilizers. Fish survival and fish weight in rice-fish farming were not significantly different from fish monoculture. Keywords: inorganic fertilizer, monoculture, productivity, soil nutrients

Abstract:
This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Abstract:
Each year, over 16 million tons of poultry litter is produced in the United States. Federal and state regulations now limit the amount of poultry litter that can be land-applied, making it difficult to store and dispose of poultry litter. The objective of this study was to evaluate composted poultry litter (CPL) as a fertilizer source for bedding plants at various rates in comparison with commercially available inorganic fertilizers in regard to plant growth and nutrient leaching. Two experiments were conducted to evaluate use of CPL as fertilizer for landscape annual bedding plants. Petunia spp. ‘Celebrity Red’ and Verbena hybrida ‘Quartz Scarlet’ were planted in raised beds simulating an urban landscape. Before planting, 10 inorganic fertilizer or CPL treatments were incorporated into the raised beds, including Peafowl® brand garden-grade fertilizer 13N–5.6P–10.9K (13-13-13) at rates of 4.9 g N/m2 and 9.8 g N/m2, Polyon® 13N–5.6P–10.9K (13-13-13) at rates of 4.9 g N/m2 and 9.8 g N/m2, and CPL at rates of 4.9 g N/m2, 9.8 g N/m2, 19.6 g N/m2, 29.4 g N/m2, 39.2 g N/m2, and 49 g N/m2. Use of CPL incorporated into landscape planting beds as a fertilizer source resulted in plants equal to or larger than plants grown with conventional inorganic fertilizers. Nitrate (NO3) and ammonia (NH4) levels in leachates from plots amended with CPL were comparable with plots amended with commercial inorganic fertilizers and nitrogen (N) levels were in most cases less in plots fertilized with CPL when compared with inorganic fertilizers when the same N rate was applied. Composted poultry litter may not be able to fully replace inorganic fertilizers, but it can reduce inorganic fertilizer requirements and provide an environmentally sound alternative to poultry waste disposal as well as provide beneficial aspects for plant growth in annual bedding plants.

Abstract:
A pot experiment was conducted in the open net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh from January to June, 2007, to study the effect of organic and inorganic fertilizers on the growth, leaf yield, chlorophyll and protein contents of Stevia rebaudiana (Bert.). The experiment was laid out in completely randomized design with three replications having 16 treatment combinations. Four types of soil viz., saline, acidic, calcareous and non-calcareous soils were collected from Khulna, Tangail, Natore and Mymensingh districts of Bangladesh, respectively. Two organic (poultry manure and cow dung) and one inorganic fertilizers @ the recommended dose along with a control were used as treatment factor. The experimental results indicated that different soil types significantly influenced all parameters studied. The highest values of all parameters were obtained from the plant grown in noncalcareous soil which was identical with acidic soil for some parameters. Different types of organic and inorganic fertilizer had also significant influence on all plant parameters. In all cases, the highest values were recorded from the plant fertilized with chemical fertilizers. Poultry manure and cow dung also showed identical results with chemical fertilizer in most cases. Interaction effect of different types of soil and fertilizer showed significant variation for most of the parameters studied except chlorophyll and protein contents. Plants grown in noncalcareous soil fertilized with chemical fertilizers exhibited the best performance in most of the cases. The overall results suggested that stevia can be cultivated in noncalcareous and acidic soils fertilized with chemical fertilizers along with poultry manure favoring the productivity of stevia.DOI: http://dx.doi.org/10.3329/pa.v19i1.16986 Progress.

Abstract:
This study assesses the effect of long-term (59 years) application of organic and inorganic fertilizers on soil organic matter and enzyme activity. Total organic C, total organic N, hot water soluble C, microbial biomass C and dehydrogenase activity were evaluated in soil from the long-term field experiment in Prague-Ruzyně (Orthic Luvisol, clay loam). Total organic C and N increased significantly in soils treated with organic fertilizers (farmyard manure, compost) and in soils with a combination of organic and mineral NPK fertilizers (manure + NPK, compost + NPK, cattle manure + straw + NPK) compared to soil treated with inorganic fertilizer, cattle slurry + straw and non-fertilized control. Farmyard manure significantly increased hot water soluble C compared to the control. Dehydrogenase activity was significantly increased by all treatments compared to control. The results indicate that additions of organic matter from various sources differ in the effects on soil organic matter and biological activity. The effect of manure was the most favourable; long-term application of cattle slurry + straw is rather similar to mineral fertilization.

Abstract:
Four fertilizer trials initiated in 1986 and completed eight years later were conducted to find out the effect of using organic fertilizers vis‑a‑vis lower and higher levels of inorganic fertilizers and organic plus inorganic fertilizer combinations on hybrid coconuts. In all sites the application of inorganic fertilizers (both lower and higher levels of ammonium sulfate + KCl or NaCl) produced significant increases m nut yield, copra weight per nut and copra per tree but lowered soil pH. These increases in Yield, copra were closely associated with the correction of N and Cl deficiencies of the palms. The most profitable treatment was the lower inorganic fertilizer level followed by treatment where ammonium sulfate was substituted with organic fertilizers (organic + KCl or NaCl). A commercial organic Sagana 100 fertilizer either applied singly or in combination with inorganic Cl proved argonomically effective but its prohibitive cost made it uneconomical to use. Apparently organic fertilizers which are available in the farms and are much cheaper proved economical but need to be combined with Cl to be effective.

Abstract:
Potted chrysanthemums as one of high-demand potted ornamental plants are mostly cultivated using inorganic fertilizers. The organic fertilizers use as an alternative and complementary to inorganic fertilizers on potted chrysanthemum cultivation needs to be studied further. This study aims to determine the response of inorganic and organic fertilizer to agronomic characters of three potted Chrysanthemum varieties. The research was carried out in West Sumatra AIAT’s greenhouse from October to December 2020 using split-plot design with three replications. The main plots were fertilizer treatments (control, inorganic fertilizers, Bio-urine organic fertilizers) and sub-plots consisted of three potted chrysanthemum varieties (Armita, Avanthe, and Naura). Bio-urine organic fertilizers nutrient content N, P and K. The results showed that agronomic character of plant height, leaf length, leaf width, and the number of internodes resulted from type of fertilization treatments were significantly different. The highest plant height, leaf width, and number of internodes were significantly achieved in inorganic fertilizers then followed by Bio-urine organic fertilizers and control. The highest growth for the characters of plant height, stem diameter, leaf length, leaf width, petiole length, and flower diameter were attained from Avanthe. The interaction between fertilizers types and varieties was not significantly different in all observed characters.

Abstract:
[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

Boosting crop productivity can be attained through the application of inorganic fertilizer; however, safeguarding the environment for future generations is overbearing especially for continuous increase in the world population. Sustainable crop productivity might be attained through the judicious use of both organic and inorganic fertilizers. The substitution of parts of inorganic fertilizers with organic fertilizer could maintain and sustain soil productivity and improve crop productivity. This paper has reviewed the past research work carried out by various scientists. A comprehensive literature review revealed that integrated nutrient management enhances maize yield, nutrient uptake, and economic return compared with the sole application of organic and inorganic fertilizers.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2014 with a view to finding out the effect of age of seedlings at staggered planting and nutrient management on growth of aromatic fine rice (cv. BRRI dhan38). The experiment comprised three ages of seedlings viz., 30, 45 and 60-day old and six treatment of nutrient managements viz. control (no manures and fertilizers), recommended dose of inorganic fertilizers, 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 and 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. The effect of age of seedlings and nutrient management and their interaction were significant on crop growth characters of aromatic fine rice. The result revealed that the highest plant height, total tiller hill-1, total dry matter production hill-1 and CGR were found when 30-day old seedlings were transplanted. Among the nutrient managements the highest growth parameters was obtain in 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 due to the continuous supply of nutrients by the combination of organic and inorganic fertilizer which led to better growth in plants. In 30-day old seedlings with 75% inorganic fertilizer + poultry manure @ 2.5 t ha-1 treatment performed best in case of all growth parameters, while the lowest one was observed in 60-day old seedlings with control. Therefore, 30-day old seedlings with 75% inorganic fertilizer + poultry manure @ 2.5 t ha-1 treatment might be a promising practice in aromatic fine rice cultivation in terms of growth performance.

<abstract> <p>The decrease in soil productivity and quality caused by the continuous and abusive use of mineral fertilizers makes necessary to adopt more sustainable agricultural soil management strategies that help to maintain soil edaphic fertility. In light of these considerations, we have evaluated the effect of organic vs. inorganic fertilization on soil microbial communities, soil quality, and crop yield in a melon crop. The following treatments were tested: i) aerobic sewage sludge from a conventional wastewater treatment plant (WWTP) using aerobic bacteria (SS); ii) aerobic sewage sludge from a WWTP using a bacteria-microalgae consortium (B); iii) N-P-K mineral fertilizer (M); iv) a treatment in which 50% of the N was contributed by SS and 50% by mineral fertilizer (M + SS); v) a treatment in which 50% of the N was contributed by B and 50% by mineral fertilizer (M + B); and vi) a no-fertilized control soil. Melon yield and fruit quality were determined in addition to several soil physical, chemical, biochemical and microbiological parameters. Organic fertilizers (SS and B) increased the percentage of soil water-stable aggregates (52 and 60% respectively) as well as the content of organic C (18 and 31%), water soluble C (21 and 41%), N (15 and 41%) and available P content (41 and 82%) compared to inorganic fertilization. They also stimulated bacterial and fungal abundance to a greater extent than mineral fertilizers (189 and 242% vs 85%, and 57 and 122% vs 29%, respectively), as well as soil respiration, and dehydrogenase, β-glucosidase, phosphatase, urease, and glycine aminopectidase activities. The analysis of principal components with parameters linked to soil quality clearly showed that organic fertilizers cause a greater improvement in soil characteristics and microbial community than mineral fertilizers. Results demonstrate that organic and combined fertilization could be used as substitutes for nitrogen mineral fertilizers in melon crop, since these treatments led to similar melon production and quality while improving soil characteristics and microbial population size and activity.</p> </abstract>

Abstract:
Selected fertilizer treatments were applied to vinca (Catharanthus roseus `Peppermint Cooler') in the landscape to determine their effect on growth and nutrient leaching. In plots 0.9 m × 2.3 m, inorganic fertilizers were applied as either a single application of 4.9 g N/m2 pre-plant, or a split application with 4.9 g N/m2 applied pre-plant followed by application of 2.45 g N/m2 at 8 and 12 weeks after planting (WAP). Inorganic fertilizers included 15N–0P–12.6K granular fertilizer, Osmocote 14N–6.0P–11.6K, and Osmocote 17N–3.0P–10.1K controlled-release fertilizers. Three different organically based fertilizers were applied pre-plant and were composed of recycled newspaper amended with animal manures (chicken, beef cattle, or dairy) and adjusted with (NH4)2SO4 to achieve C:N ratios of either 20:1 or 30:1. A standard industry treatment of 13N–5.6P–10.9K (4.9 g N/m2) incorporated pre-plant and 17N–3.0P–10.1K (4.9 g N/m2) topdressed post-plant was also included. Leachates, collected with lysimeters, from inorganic fertilizer plots had lower levels of total N (NO3– + NH4+) compared to organically based fertilizer plots through 8 WAP. Of the inorganic fertilizer plots, those receiving 15N–0P–12.6K granular fertilizer had higher total N levels at 1, 2, and 4 WAP than other inorganic fertilizer plots. Total N in leachates declined over the study and by 12 WAP were similar among all treatments. Vinca treated with organically based fertilizers (C:N 20:1) had the highest foliar color ratings through 8 WAP; however, color ratings declined thereafter and by 16 WAP had the lowest ratings. Plants treated with organically based fertilizers had greater shoot dry weights 20 WAP and larger growth indices 8 and 20 WAP.

Abstract:
Background Corn silage is an important feed for intense ruminant production, but the growth of corn relies heavily on the use of chemical fertilizers. Sustainable crop production requires careful management of all nutrient sources available on a farm, particularly in corn-based cropping systems. Methods Experiments were conducted to determine the appropriate technique of corn-legume intercropping in conjunction with the supplemental use of chemical fertilizers, organic manure, and biofertilizers (BFs). Acetylene reduction assays (ARAs) were also performed on corn and soybean roots. Results Combining chemical fertilizers with chicken manure (CM) in a 50:50 ratio and applying 50% NPK+50% CM+BF produced fresh forage and dry matter (DM) yields that were similar to those produced in the 100% nitrogen (N), phosphorus (P), potassium (K) treatment. Among the lone fertilizer treatments, the inorganic fertilizer (100% NPK) treatment produced the highest DM yield (13.86 t/ha) of forage and outyielded the 100% CM (9.74 t/ha) treatment. However, when CM was combined with NPK, the resulting DM yield of forage (13.86 t/ha) was the same as that resulting from 100% NPK (13.68 t/ha). Compared with CM applications alone, combinations of NPK and CM applications resulted in increased plant height, crop growth rates (CGRs) and leaf area index (LAI), but the values of these parameters were similar to those resulting from 100% NPK application. Fertilizers in which the ratio was 50% CM+50% NPK or 50% CM+50% NPK+BF resulted in protein yields that were similar to those resulting from conventional fertilizers. Similarly, the CP content did not significantly differ between applications of the 100% NPK and 50% CM+50% NPK fertilizers. The use of BFs had no significant impact on improving either the yield or quality of forage fertilized with inorganic or organic fertilizer. Lactic acid responded differently to different fertilizer applications and was significantly higher in the fertilized plots than in the unfertilized plots. Compared with treatments of lone chemical and lone organic manure fertilizers, treatments involving applications of BF and a combination of BF and NPK or CM resulted in higher ARA values. Discussion There is no simple and easy approach to increase biological nitrogen fixation (BNF) in grain legumes grown as part of a cropping system under realistic farm field conditions. Overall, evidence recorded from this study proves that, compared with corn monocrops combined with CM and chemical fertilizers, corn-soybean intercrops could increase forage yields and quality, produce higher total protein yields, and reduce the need for protein supplements and chemical fertilizers.

Abstract:
Inorganic fertilizers with major nutrients are likely to be contaminated with some micronutrients. Fertilizers, utilized in Saudi Arabia, were analyzed for their total and water-soluble content of Fe, Zn, Mn and Cu. They represented three categories namely: phosphatic, solid multiple nutrient fertilizers (SMNF) and water-soluble multiple nutrient fertilizers (WSMF). Total iron content in examined fertilizers was higher in phosphatic fertilizers and lower in WSMF. Nevertheless, only a very small portion of the total iron content is likely to be available to plants. It was estimated, on the basis of total content, that almost 2 g of iron would be applied to soil for each added kg of phosphatic fertilizer. The highest total content of Zn was recorded for phosphatic fertilizers. The data suggested that less than half kg of Zn would be accumulated in soil if 500 kg of phosphatic fertilizers were applied in one year. This value however, fell dramatically, to one fourth of the value, when only the available forms of Zn were considered. Fertilizer content of manganese and copper were lower than both Fe and Zn. Micronutrient impurities present in inorganic fertilizers might not have an immediate influence on plant nutrition due to their lower solubility.

However, our knowledge on how organic–inorganic fertilizers application affects soil bacterial communities remains largely poorly understood. In this study, we investigated the long-term effects of different organic–inorganic fertilization strategies: without fertilizer (CK), fertilizers NPK (CF), fertilizers NPK, plus 30% organic manure (CFM1), and fertilizers NPK plus 60% organic manure (CFM2) on soil bacterial communities in paddy fields. Results showed that the bacterial 16S ribosomal DNA (rDNA) gene abundances in treatments CF, CFM1, and CFM2 were 1.44, 1.54, and 1.28 times higher than that in CK and the ACE index in treatment CFM1 was 9.0% greater than that in treatment CFM2, respectively. Fertilization strategy significantly changed the relative abundance of Nitrospirae, Gemmatimonadetes, and unclassified bacteria at the phylum level and bacteria belonging to order Nitrospira, candidate bacterium SBR2076, unclassified bacteria, Syntrophobacterales, and Solibacterales at the order level, respectively. High organic–inorganic fertilizer application rates inhibited the growth of Nitrospirae by 20–35%, and stimulated the growth of Gemmatimonadetes by 14–77%, relative to the rest of the treatments, respectively. Hierarchical cluster and principal coordinate analysis (PCoA) showed that the fertilization strategy affected the bacterial community structures, and the organic–inorganic fertilized treatments possessed similar bacterial community structures. Furthermore, soil pH, total nitrogen (TN), and soil organic carbon (SOC) were the main driving factors altering the bacterial communities. Our results suggested that combined organic–inorganic fertilizers application increased soil nutrient contents and bacterial abundances, and this could be an optimized fertilization strategy in regulating soil bacterial communities for rice production.

Abstract:
An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2014 with a view to finding out the effect of age of seedlings at staggered transplanting and nutrient management on growth and yield of aromatic fine grained rice (cv. BRRI dhan38). The experiment consisted of three ages of seedlings (30, 45 and 60 day-old) at staggered transplanting and six nutrient managements viz. control (no nutrients), recommended dose of inorganic fertilizers, 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 and 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. The effect of age of seedlings at staggered transplanting, nutrient management and their interactions were significant on crop characters, yield components and yield of aromatic fine rice. The tallest plant was recorded due to transplanting 30- day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The highest leaf area index (6.55), number of total tillers hill-1 (12.56), number of effective tillers hill-1 (8.54), panicle length (24.07cm) and number of grains panicle-1 (141.3) were recorded in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 while the lowest values were recorded in 60-day old seedling with control. In case of sterile spikelets panicle-1, 60-day old seedlings with control treatment showed the highest value (30.94). The highest grain (3.85 t ha-1) and straw (5.29 t ha-1) yields were obtained in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. Therefore, 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 appeared as the promising technique for appreciable growth and grain yield of aromatic fine grained rice (cv. BRRI dhan38).SAARC J. Agri., 16(1): 49-59 (2018)

Abstract:
In this paper author trying to give the attention on eco-friendly fertilizers rather than the commercially<br />available inorganic fertilizers. Here different types of eco-friendly fertilizers, i.e., organic fertilizers<br />and some types of slow or Controlled Release Fertilizers (CRF) including Glass Fertilizer were<br />described with their nutrients release mechanism. The environmental hazardous effects, i.e.,<br />disadvantages of different common commercially available fertilizers and advantages of organic<br />fertilizer and controlled release fertilizers including Glass Fertilizer over common inorganic fertilizers<br />properly explained here. There are numerous crops and plants which have different growing habits and<br />nutrient requirements. The fertilizers help us in understanding the precise needs and requirements of<br />the plants fulfilling which maximum production can be reached. The blended mixtures of measured<br />quantities of the nutrients enable the plants to get potential nutrition and help them to hasten growth<br />and yield more than their usual capacity. The fertilizers are highly soluble and do not take much time to<br />get dissolved in the soil and reach the plant in no time. However, it happens only in the case of<br />chemical fertilizers and organic fertilizers take time to be dissolved. Moreover, agricultural fertilizers<br />are a combination of hazardous and beneficial fertilizers. Organic fertilizers are not as harmful as the<br />inorganic ones however the former takes more time than the latter top reach the roots of the concerned<br />plants. Excessive fertilization does encourage great yields however also invites air, water and soil<br />pollution. Therefore, it is very necessary to use fertilizers in limited quantities and if possible then<br />organic and inorganic should be used simultaneously to counterattack the miscellaneous soil hazards.

Abstract:
AbstractThe demand for organic foods is increasing globally, but a key limiting factor to the production of organic greenhouse produce is the lack of certified liquid fertilizers. In this experiment, four organic fertilizers were produced using either acidic extraction, anaerobic digestion or both of ensiled biomass of organic red clover and white mustard. The resulting fertilizers were applied to greenhouse-grown parsley either alone, or in combination with nitrogen (N)-enriched water produced by flushing acidic water with ammonia, to determine their effect on plant growth and the nutrient concentrations of parsley. Six combinations of fertilizer treatments were included in the greenhouse experiment. Three treatments received either fertilizers derived from acidic extraction, anaerobic digestion or both and three treatments received fertilizers derived from acidic extraction combined with N-enriched water. Conventional inorganic liquid fertilizer, chicken manure extract and no liquid fertilizer (only water) were added as control treatments. A higher N-min (ammonium and nitrate) to potassium (K) ratio was found in fertilizers after anaerobic digestion compared to acidic extraction. All organic fertigation treatments resulted in high pH, high K and chloride concentrations and high NH4/NO3 ratios in the root zone. In addition, high electrical conductivity (EC), P, K and Mg concentrations were found when only acidic extracted fertilizers were applied. Application of plant-based organic fertilizers without amending with N-enriched water resulted in biomass yields that were 21–26% lower than the inorganic fertigation control. However, fertigation with chicken manure extract, or a combination of fertilizer derived from acidic extraction and N-enriched water, resulted in similar plant growth as inorganic fertilizer. The lower yield from fertilizer derived from acidic extraction was due to elevated EC levels in the growing medium. Our results suggest that yield of greenhouse-grown parsley using either organic fertilizers combined with N-enriched water or chicken manure extract is similar to conventional fertilizer.

Abstract:
Organic manures are eco-friendly alternatives to inorganic fertilizers. However, a large volume of organic inputs is needed to meet the nutritional requirements of crops. Hence, there is a need to combine them with inorganic fertilizers to attain better crop yield. This study was conducted to evaluate the effects of the combined application of organic and inorganic fertilizers on the growth and yield performance of sweetcorn and on the profitability of sweetcorn production. The treatments were as follows: T0 - -1 Control (without fertilizer applied), T1 - Inorganic fertilizer at 90-60-60 kg ha -1 -1 (N, P O , K O), T - 5 t ha of vermicompost + 45-30-30 kg ha N, P O , K O, T - 5 2 5 2 2 2 5 2 3 -1 -1 -1 t ha of poultry manure + 45-30-30 kg ha N, P O , K O, T - 5 t ha of cow 2 5 2 4 -1 -1 manure + 45-30-30 kg ha N, P O , K O, T - 5 t ha of goat manure + 45-30-30 2 5 2 5 -1 -1 -1 kg ha N, P2O5 , K2O, T6 - 5 t ha of mudpress + 45-30-30 kg ha N, P2O5 , K2O, T7 - -1 Foliar spray (Fermented Golden Snail) + 45-30-30 kg ha N, P O , K O. The 2 5 2 experiment was laid out in RCBD with 3 replications. Results showed that sweetcorn plants applied with organic + inorganic fertilizers regardless of source had comparable growth and yield performance to plants applied -1 with pure inorganic fertilizers. The highest net income of PhP62,086.00 ha was obtained from plants applied with combined goat manure and inorganic fertilizers. This suggests that in sweetcorn production, it is feasible to reduce the use of inorganic fertilizers by combining them with organic fertilizers

Efforts to increase soybean productivity can be made with the application of organic and inorganic fertilizers. Large amounts of organic fertilizer are required to give a positive impact on soybean yield. However, this practice is deemed inefficient in terms procurement and transportation, making farmers less interested. The addition of inorganic fertilizer or the use of nutrient-rich organic fertilizer (Santap NM2) is among the solutions. The objective of this research was to formulate management techniques for organic and inorganic fertilizers application on the early-medium maturing soybean line, Lokal Jateng/Sinabung-1036, to achieve the soybean’s maximum potential yield. The research was conducted on Alfisols at Muneng Research Station, Probolinggo, and Vertisols at Ngale Research Station, Ngawi, in the dry season of 2012. The experiment was performed in a randomized complete block design with factorial, with three replications. The first factor was four doses of organic fertilizer and the second factor was four combination doses of ZA, SP-36, and KCl fertilizers. On the Alfisols of Probolinggo, Lokal Jateng/Sinabung-1036 soybean did not require additional inorganic fertilizers to achieve a yield of 2.71 t/ha, whereas on the Vertisols of Ngawi, Lokal Jateng/Sinabung-1036 soybean need 2 t /ha Santap NM2 to increase its yield from 2.60 t/ha to 2.81 t/ha.

The experiment comprised six fertilizer managements viz., control (no manures and no fertilizers), recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha-1, respectively), 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1, and 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 and four weed managements viz., control (no weeding), pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + one hand weeding at 35 DAT, post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 + one hand weeding at 35 DAT, pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1. The experiment was laid out in a factorial randomized complete block design with three replications. Growth traits of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated fertilizer and weed management. Plant height, number of tillers hill-1, total dry matter, leaf area index (LAI) and crop growth rate (CGR) gave their highest values in 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 while their corresponding lowest values were found in control. So it can be concluded that, the interaction of 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along with pre-emergence herbicide (Panida 33 EC @ 2.5 l ha-1) + post-emergence herbicide (Granite 240 SC @ 93.70 ml ha-1) appears as the promising combination in respect of growth performance of aromatic Boro rice (cv.

The objectives of this research were to determine the effect of natural materials added to the rice straw fermentation process; and to find the best formula for organic fertilizers to increase nutrient uptake, growth, and rice grain yield in newly opened and intensive lowland. The research was conducted at West Sumatra AIAT’s laboratory and lowlands at Dharmasraya Regency, West Sumatra Province, Indonesia from July to December 2017. The first research included three formulas of organic fertilizers and the second included six treatments produced from the first research. The results showed that increasing amount of titonia from 200 kg to 400 kg and rock phosphate from 5 kg to 20 kg per ton of rice straw increased compost’s nitrogen and phosphorus content of the compost from 1.22% to 1.36%, and from 0.75% to 1.68% respectively. Application of compost without inorganic fertilizers in newly opened lowland decreased 23% of yield and increased 4.7% yield when combined with inorganic fertilizers. The combined application of organic and inorganic fertilizers increased 10-12% yield and decreased 10% of yield without inorganic fertilizers in intensive lowland. Application of organic fertilizer without inorganic fertilizers not significantly influenced the growth. Combination of organic and inorganic fertilizers is the best way to increase lowland rice yield.

Abstract:
The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers.

Abstract:
Rice is the most important staple cereals in human nutrition and consumed by 75% of the global population. Rice plant needs supply of essential nutrients for its optimal growth. Rice production has been increased tremendously in India after green revolution combined with insensitive irrigation and use of inorganic fertilizers and pesticides. However, the effect of using inorganic fertilizers has resulted in contamination of ground water and decreased the productivity of soil, which in turn affects the rice production in long term. Use of organic manure may help to regain the soil health but they are insufficient to provide the essential nutrients to achieve optimal growth. So, use of organic manures combine with inorganic fertilizers are followed to obtain optimum yields. This study aimed to test the effect of the different organic fertilizer and combinations of organic and inorganic fertilizers on the qualitative and quantitative parameters of two cultivars of rice as DRR Dhan 39 and RP.BIO.226. The experiment was conducted on the farm located at Fasalwadi village, Sangareddy district, Telangana during kharif season in randomized complete block design with three replications. The treatment included two controls and 10 combinations of four organic fertilizers as farmyard manure, vermicompost, Panchagavya, Jeevamrutha and inorganic fertilizers as combination of 60:75:75 levels of N, P and K. Grain and straw samples were collected and physical parameters were measured at harvest stage. The results indicated that the variety DRR Dhan 39 gave the statistically significant (P<0.0001) higher grain yield of 8713 kg/ha and straw yield of 9483kg/ha with 50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK. On the other hand, the variety of RP.BIO.226 gave the highest grain yield of 6390 kg/ha with Vermicompost, Jeevamrutha 5% and Panchagvya 3% (8 t/ha, foliar spray and 500 litres/ha) and highest straw yield of 7430 kg/ha with T10 treatment (50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK). Both varieties of rice poorly responded to inorganic fertilizers with lower grain and straw yield. Statistically significant differences were observed in both varieties of grain crude protein (CP%), straw acid detergent fiber (ADF%), crude fiber (CF%) and acid detergent lignin (ADL%) with different fertilizers

Abstract:
Aquaculture offers the opportunity for safeguarding local and global food security in the face of declining capture fisheries. However, the form of aquaculture that is commonly practiced in Kenya is characterized by the use of agrochemicals such as fertilizers that negatively impact biodiversity especially when effluents from fish ponds drain into water bodies. This study aimed to determine differences in the growth rate of Clarias gariepinus, an important aquaculture fish in Kenya, to assess plankton diversity, and to identify phytoplankton species associated with pollution under organic and inorganic fertilization regimens using chicken manure, Diammonium phosphate, and urea, respectively. Average growth rate calculated per day was higher in the organically-fertilized ponds at 0.06 cm/day, followed by inorganically-fertilized ponds at 0.05cm/day and then, the control at 0.04 cm/day. Average weight gain was higher in organically-fertilized ponds at 0.08 g/day followed by ponds fertilized with inorganic fertilizer at 0.07 g/day and the control, at 0.06g/day. There were significant differences in growth rate across fertilization regimens (length: F2, 264= 24.06, p = 0.0399; weight: F2, 264 = 20.89, p = 0. 0457). Specifically, although differences in growth rate of fish in organically and inorganically fertilized ponds were not significant, fish in fertilized ponds were on average, longer and weighed more than those in the control pond. Jaccard’s similarity index for phytoplankton was highest (0.38) between organically-fertilized ponds and control but lowest (0.25) between inorganically-fertilized ponds and control. Use of chicken manure produced the highest diversity of zooplankton (Shannon-Weiner’s H in organically-fertilized pond = 1.886; inorganic = 1.044, and control = 0.935). The use of DAP and urea produced the highest proportion of phytoplankton species associated with pollution. These results do not support the commonly reported notion that ponds fertilized using inorganic fertilizers are more productive. Findings suggest that the use of inorganic fertilizers may threaten biodiversity in aquatic ecosystems through the production of toxic algae.

Abstract:
The impact of nutrient sources cannot be over emphasised in plant growth. Seedlings of Annona muricata were subjected to organic fertilizers, inorganic fertilizers and fertilizer-free treatmentsin this study. The organic fertilizers comprises of cow dung, poultry manure and water hyacinth, while NPK fertilizer was used as the inorganic manure and Top soil without fertilizer application was used as the control. The organic fertilizers were singly used and mixed at the rate of 100kg/ha and 200kg/ha while the inorganic fertilizer was used at the rate 100kg/ha and 200kg/ha. The parameters taken were plant height, stem girth, leaf area and leaf production. Results obtained showed that poultry manure produced the tallest plants (23.50cm) at 3months after transplanting though this was not significantly different from those of cow dung manure (23.00cm). NPK fertilizer produced the plant with highest leaf area (32.75cm) and stem girth (2.25cm) at 3 months after transplanting and was not significantly different from the organic fertilizers (Poultry manure 200g/ha, Cow dung 200g/ha, Water hyacinth 100g/ha and 200g/ha). NPK fertilizer also produced the highest number of leaves at the end of the three month assessment (31.00cm). All the growth parameters observed showed that the control experiment gave the least performance. The results obtained tend to suggest that the use of NPK fertilizer should be recommended for growing Annona muricata and improvement of the soil nutrients level.

Abstract:
Fertilizer is the most important thing in terms of caring for plant growth. This was identified because fertilizer has nutrient mineral elements which are really needed by the plants themselves. Fertilizer itself is divided into organic and inorganic fertilizers. Still related to the type of fertilizer itself, in order to get plants with good quality and cultivation, the fertilizer given must be balanced because it is in line with the contents that exist in each type of fertilizer. Inorganic fertilizer or better known as chemical fertilizer is more popular with many people because of its practicality, but it should be remembered that excessive use of chemical fertilizers also have a negative impact on soil fertility. Therefore organic fertilizer still plays a role in the field of inorganic fertilizer in order to offset the need for soil itself. Understanding the importance of a balance between organic and inorganic fertilizers, the community service conducted by providing training in making Guano fertilizer at SMK Muhammadiyah 3 Morowudi Gresik was chosen to be applied. Guano fertilizer was chosen as an alternative to the addition of a companion formula rather than inorganic fertilizer because of its content which is rich in nitrogen, phosphorus, postasium which is needed by plants. Efforts to provide training to students of SMK Muhammadiyah 3 Morowudi Gresik are also expected to be able to boost cooperation than the students themselves in developing their potential to contribute to the community and schools

Abstract:
A field experiment was initiated at the Central Soil Salinity Research Institute, Karnal, India between 1994 and 1998 involving use of NPK fertilizers alone and in combination with green manure (Sesbania bispinosa) or farmyard manure (FYM) in a rice–wheat cropping sequence. An attempt was made to evaluate the effect of the substitution of inorganic fertilizers with organic manures on yields of grain and nutrients, economy and soil fertility during 1997–98 and 1998–99. Application of NPK and its combination with green manuring and FYM increased the rice yield significantly. Applying inorganic fertilizers resulted in similar nitrogen use efficiency (NUE) in rice as compared with organic manures along with inorganic fertilizers, but NUE was increased in wheat by the residual effect of organic manures along with inorganic fertilizers. The responses of rice to the application of the full recommended amount of inorganic fertilizers (120 kg N, 26 kg P and 42 kg K/ha) and its combined use with green manure or 10 t/ha FYM and 150% recommended amount (180 kg N, 39 kg P and 63 kg K/ha) were 2·98, 4·27, 4·10 and 3·54 t/ha, respectively. Further, with green manure or 10 t FYM/ha in combination with 50% recommended amount, the mean rice yield (5·8 t/ha) was similar to the yield (5·5 t/ha) obtained from the 100% NPK recommended treatment. Application of green manure or 10 t FYM/ha thus saved 60 kg N and 13 kg P/ha inorganic fertilizer in rice. The residual effect of green manure or FYM plus the full recommended fertilizer amount (120 kg N, 26 kg P and 42 kg K/ha) was significantly greater than that of the full recommended amount of fertilizer. Addition of green manure or FYM resulted in higher removal in crops, increase of soil N, P, K and organic C, and reduced soil pH. Application of the full recommended amount of fertilizer only maintained the N, P and K status in soil. Higher profit was obtained when inorganic fertilizer was combined with organic manures.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during December 2014 to May 2015 to study the effect of integrated fertilizer and weed management on the yield and gain protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised six sets of fertilizer managements. 1. Negative control having no fertilizers and no manures, 2. Recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha-1, respectively), 3. 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 4. 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 5. 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1, 6. 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. Four weed managements 1. Control (no weeding), pre-emergence herbicide, 2. Panida 33 EC + one hand weeding at 35 DAT, 3. Post-emergence herbicide, Granite 240 SC + one hand weeding at 35 DAT and 4. Pre-emergence herbicide, Panida 33 EC + post-emergence herbicide, Granite 240 SC. The highest grain yield (6.40 t ha-1), grain protein content (7.79%) and benefit cost ratio (2.20) were obtained from 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 while their corresponding lowest values were found inweedy check without fertilization. Weed infestation reduced 58.28% grain yield in control plots due to crop-weed competition compared to plot receiving pre-emergence herbicide + post-emergence herbicide. It can be concluded that 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 combined with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 may be used to obtain the highest grain yield and grain protein content of aromatic Boro rice (cv.

Abstract:
The rising cost of inorganic fertilizers, coupled with their adverse effects on soil conditions, has resulted in increasing interest in organic amendments. The objective of the present study was to evaluate the effect of organic amendments (OAs) with different C/N ratios on nitrogen use efficiency (NUE) and recovery rate, as well as on the growth and yield of Zea mays and soil properties. A precise pot experiment was conducted on a low-fertile, sandy-loam soil, and the dynamics of nitrogen (N) were also analyzed by the A-value method, using 15N tracer. The plant height of the treatment groups decreased in the following order: inorganic fertilizer (IF) = rapeseed waste (RW) > chicken manure (CnM) > bamboo tealeaf (BTL) > cow manure (CwM) > bamboo compost (BC). Furthermore, the maize fertilized with RW only took up half of the N in IF, despite producing the same yield, which indicates that the physiological nitrogen efficiency (PUE) of RW was twice as high as that of IF. RW and CnM were regarded as valuable fertilizers that could be used to replace inorganic fertilizers. A linear relationship between the N mineralization of the OAs was obtained by an incubation test and the pot experiments, estimating the effect of OA application on the maize. Maize plants mainly absorbed N derived from fertilizers; however, for the both sources of N (fertilizer and soil), N was mainly accumulated in grains followed by the leaves, stem, and root, suggesting that studies should be conducted to improve soil N use efficiency.

Abstract:
Water scarcity is one of those issues. Reuse of wastewater from textile industries is a very common strategy to cope with water scarcity. Continuous use of effluent water for agricultural purposes results in negative impacts on physicochemical properties of soil and plant. Organic fertilizers are considered beneficial for soil and crop quality. To exploit the strategies to use this effluent water safely for crop production a pot experiment was conducted with different combinations of organic and inorganic fertilizers viz. T1= Control (tap water + Recommended dose of NPK (130, 95 and 65 kg ha-1), T2=Wastewater + Recommended dose of NPK, T3=Wastewater + Organic fertilizer (200 kg ha-1) + Remaining NPK from inorganic fertilizer, T4=Wastewater + Organic fertilizer (400 kg ha-1) + Remaining NPK from inorganic fertilizer, T5 =Wastewater + Organic fertilizer (600 kg ha-1) + Remaining NPK from inorganic fertilizer and T6=Wastewater + Organic fertilizer (800 kg ha-1) + Remaining NPK from inorganic fertilizer. It was observed that integrated use of organic and inorganic fertilizer (800 kg ha-1 organic and remaining of recommended dose from inorganic fertilizer + effluent water) enhanced the growth and yield of wheat crop. In a study found that the use of organic fertilizer could help mitigate the negative impact of textile effluent water on wheat growth.

Abstract:
The efforts to improve the productivity of soybean can be done through technological innovation by the provision of chemical fertilizers and mycorrhizae. This study were aimed to obtain information on the effect of a single fertilizer, which can provide the same or higher level of soybean crops if compared with those compound fertilizers, as well as to find out the effect of mycorrhizae to the improvement of efficiency in the use of inorganic fertilizers. It is expected that the mycorrhizae inoculation can reduce single fertilizer’s dose to the level equivalent to the compound fertilizer given by farmers. The study was conducted in Bleberan Village, Playen Subdistrict, Gunung Kidul Regency, Yogyakarta from February to May 2015. It was conducted by using a two-factors factorial design arranged in a randomized block design with three replications. The first factor was inorganic fertilizer (N, P2O5 and K2O), consisting of 5 levels, i.e. without fertilizer (0-0-0 kg/ ha), Phonska fertilizer (45-45-45 kg/ha), single fertilizer (45 -45-45 kg/ha), a low single fertilizer (23-36-30 kg/ha) and high single fertilizer (23-108-90 kg/ha). The second factor was mycorrhizal inoculation, consisting of three levels, i.e. without mycorrhizae (0 g), medium dose (2.5 g) and high dose (5 g). Data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. If there was a significant difference, analysis was followed by Duncan Multiple Range Test with a significance level of 5%. The relationship between variables observed was examined by a correlation analysis. The results showed that there was no interaction between inorganic fertilizer and mycorrhizal application. The dose of single fertilizer which was equivalent to the dose of compound fertilizer given to soybean could increase crops by 1.37 t/ha compared with plants treated with a compound fertilizer 1.13 t/ha. The results of correlation analysis among parameters showed that there were correlations between the grain crops and height (r = 0.506**), stem diameter (r = 0.303*), and the number of pods per plant (r = 0.313*).

Abstract:
Excessive use of inorganic fertilizers is suspected to be the cause of low productivity and poor bulb storability that reduced their use. Goat manure organic fertilizer (GMOF) can be an alternative in reducing the use of these inorganic fertilizers. The study was conducted in March to June 2019 in the shallot field at Sukorejo Village, Rejoso District, Nganjuk Regency, East Java. The research aims to determine the dose of inorganic fertilizer which can be reduced by adding goat manure to increase the growth and production of shallot bulbs. This experiment used 2 factors, namely manure consisting of 2 levels (0 and 10 tons ha-1) and inorganic fertilizer consisting of 5 levels (0, 25, 50, 75, and 100% inorganic fertilizer reference dose). The treatment was repeated 4 times so that there were 40 experimental plots with a size of 2 m x 4 m, using Super Philip variety. The addition of 10 tons ha-1 of GMOF to shallot cultivation in Nganjuk Regency could reduce the use of inorganic fertilizer to 50%. Keywords: goat manure, nutrient uptake, organic, Super Philip

Natural soils at times do not supply sufficient amount of nutrients for the crops including cabbage, an important vegetable crop in the tropics. Therefore it is necessary to add fertilizer to supplement the soil nutrients to optimize crop growth and production. A study was conducted to examine seven different rates of inorganic fertilizers Cap Daun at 0.5, 0.75, 1, 1.25 and 1.5 of the recommended rate with the no fertilizer as the control. The results showed that inorganic fertilizer treatment generally improved the growth and yield of cabbage compared to the control. The number of leaf, yield per plant, yield per plot, and yield per ha of cabbage treated with inorganic fertilizers was significantly higher than the control treatment. The recommended rate for cabbage plants is 0.5 recommendation rate, which means applying 136 kg.ha-1 of inorganic fertilizer and urea fertilizer of 64 kg.ha-1 and SP-36 27 kg.ha-1 applied twice, 50% at 1 WAP and the rest at four WAP to get the best results.

ABSTRACT The effects of inorganic (ammonium nitrate and triple superphosphate) and organic (fish bone-meal) fertilizers on the biodegradation rates of Venture condensate within a sand-beach environment were assessed over 333 days. Field results showed that the organic fertilizer stimulated microbial growth and metabolic activity to the greatest extent. However, based on chemical analysis of residual oil concentrations and composition, the application of inorganic fertilizers was the superior bioremediation strategy. This paradox between microbiological and chemical results was attributed to the selective growth of different bacterial populations, the preferential use of components within the organic fertilizer over oil by the indigenous microflora, and the production of toxic metabolic by-products from the degradation of the organic fertilizer.

Balanced fertilization is the key factor to improve the efficiency and effectiveness of fertilization.The dosage of inorganic fertilizers applied can be determined based on the nutrient status of P, K and rice productivity. The research aims to improve balance fertilization that combines inorganic fertilizers, which is set up based on soil nutrient status, and organic fertilizers. The research was conducted in Karang Tanjung Village, Padang Ratu District, Central Lampung, in the dry season of 2009 until 2012. An experimental plot of one hectare was set up in the farmer’s paddy fields. Generally, the plot for every treatment was owned by two or more farmers. The treatments consisted of the dose of fertilizer applications for lowland rice, namely (1) dose of fertilizers based on farmer practice, (2) dose of fertilizers proposed by Petrokimia, (3) 75% of fertilizer dose that was set up based on soil analysis plus straw compost, and (4) 75% of inorganic fertilizer combined with manure and biofertilizer. At the fourth growing season, each plot was applied with 100% inorganic fertilizer (NPK fertilizer). The results showed that the limiting factor of the soil used in the current study is the content of organic-C, N, K, and CEC. The compost of rice straw used as organic matter in the current study contains higher organic-C and total-N in comparison to manure. Organic matter application in the form of straw compost or manure can reduce 25% of NPK application, while the production of rice remains high. Fertilization on paddy soils based on soil nutrient status can improve fertilization efficiency. Rice production in the treatment of 100% NPK is similar to that in the fertilization treatments based on farmer practice and Petrokima rate.

Abstract:
This 2-year study examined the effect of fertilizers on tree growth and foliar nutrition in a Populus trichocarpa Torr. & A. Gray × Populus deltoides Bartr. ex Marsh. plantation located in southwestern Québec. The treatments included a control that did not receive N or P fertilizer, inorganic NP fertilizers, organic fertilizers applied at 65–70 kg N·ha–1, and organic fertilizers applied at 130–140 kg N·ha–1. Fertilized trees were taller and had larger diameters than control trees. Three methods were used to diagnose limiting nutrients and nutrient imbalances, and compare the nutrient supply from different fertilizer sources. The critical value approach and the compositional nutrient diagnosis methods found below-optimum N and P concentrations, sufficient K and Mg concentrations, and an excessive Ca concentration in foliage. Vector analysis compared the N nutrition in foliage from fertilized trees and the control trees. The compositional nutrient diagnosis r2(nutrient imbalance index) was negatively correlated with annual tree growth in height (r = –0.46, P < 0.05) and diameter (r = –0.59, P < 0.05), meaning that trees with a greater nutrient imbalance grew less in height and diameter than trees with balanced foliar nutrition. Of these diagnostic methods, compositional nutrient diagnosis holds promise for identifying nutrient limitations and predicting growth responses to fertilization in hybrid poplar plantations.

The use of entomopathogenic nematodes as safe biopesticidal alternatives to hazardous chemicals entails improving the prediction of their native efficacy against soil pests. The effect of ten inorganic fertilizers, used extensively in Egypt, on the virulence of indigenous Steinernema glaseri and peanut germination was examined herein. The nematode added either before or tank-mixed with 1%, 5%, and 10% concentrations of each fertilizer in a peanut field was sampled 1 and 7 days before and 1, 7, 14, 21, 28, 49, and 56 post-tank mixes to check for S. glaseri virulence via baiting soil with Galleria mellonella larvae. Phosphorus fertilizers had more adverse effects than others on S. glaseri virulence and peanut germination. Plots with only S. glaseri had high germination close to chlorpyrifos. Averages of insect mortality in soil samples of potassium, nitrogen: phosphorus: potassium (NPK), nitrogenous, and phosphorus fertilizers, and non-fertilized checks (nematode only) were 85.8, 83.8, 80, 69.2%, and 93.3% respectively. Using S. glaseri is preferred before fertilizing. Most 1% fertilizer concentrations are compatible with S. glaseri in tank mixes for short-term (1–7 days) insect control but may affect long-term control.

One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).

Abstract:
The experiment was carried out to evaluate the effects of organic and inorganic fertilizers on the yield components of okra (variety NH-Ae 47-4). Organic fertilizers (cow dung and poultry droppings) and inorganic (NPK 15:15:15 and Urea 64:0) fertilizers were used for the experiment. The fertilizers were weighed and applied at 5g, 10g and 15g and were replicated three times and each having a control. The fertilizers were mixed three days prior to sowing the seeds. Yield components taken include; fresh pod weight (g), dry pod weight (g), length of pod (cm), number of grooves on the pod, length of stalk (cm) and pod girth (cm). Application of cow dung, poultry litter, and urea and NPK fertilizer had significant effects on all the parameters accessed with Urea fertilizer having least effect. The application of cow dung resulted in significant increase in the yield components. The results obtained from the experiment also showed that the effect of the treatments were significantly difference from the controlKeywords: evaluate, cow-dung, poultry-droppings, okra, yield

Abstract:
Fertilizer is one of the most important needs for plants. Fertilizing can be done by using inorganic fertilizers or organic fertilizers. Long term fertilizing by using inorganic fertilizers without adding the organic matter could potentially reduce soil fertility and lead to not optimal growth of the plant. This study aims to determine the effect of liquid organic fertilizer (LOF) made from rabbit urine, NPK fertilizer, and the combination of both fertilizers on the growth of bok choy, and to determine the best fertilizer dosage for the growth of bok choy. This study uses a Completely Randomized Design consisting of 2 factors, the dose of rabbit urine LOF and dose of NPK fertilizer; 4 dosage levels each in triplicates. Data was analyzed using ANOVA followed by DMRT Test. The results indicates that the application of LOF made from rabbit urine, NPK fertilizer, and the combination of both fertilizers increases plant height, leaves number, leaf area, wet weight, dry weight, and chlorophyll total of bok choy. DMRT (a 5%) test shows the best dosage applied for enhancing growth parameter are 6 ml of LOF plus 0,4 gram of NPK for plant height, wet weight, and dry weight, the 4 ml of LOF plus 0,6 gram of NPK for leaves number and leaf area, and the 4 ml of LOF plus 0,4 gram NPK for chlorophyll total.

Abstract:
Two experiments were conducted to evaluate the growth and flowering responses of greenhouse-grown French marigold (Tagetes patula L. ‘Janie Deep Orange’) to two non-composted broiler chicken litter-based organic fertilizers, 4-2-2 and 3-3-3, and one commonly used synthetic controlled-release fertilizer, 14-14-14. In both experiments, fertilizer 4-2-2 was applied at four rates of 1%, 2%, 4%, and 6% (by volume); 3-3-3 was applied at four rates of 1.34%, 2.67%, 5.34%, and 8.0% (by volume); and 14-14-14 was applied at rates of 0.99, 1.98, 3.96, and 5.94 kg·m−3. In general, substrate containing different rates and types of fertilizers had a pH within the recommended range of 5.0 to 6.5. Electrical conductivity (EC) was similar among substrates containing different rates of 14-14-14; however, EC increased with increasing fertilizer rate for substrates containing 4-2-2 and 3-3-3. Substrate EC within each treatment was generally higher earlier in the experiment. For the fertilizer rates used in these two experiments, increasing 14-14-14 fertilizer rate increased plant growth and flowering performance. However, low to intermediate rates of 4-2-2 and 3-3-3 in general produced the highest plant growth index, shoot dry weight, number of flowers per plant, total flower dry weight, and root rating. Plants grown at high rates of 4-2-2 and 3-3-3 showed symptoms associated with excessive fertilization. Plant tissue nitrogen (N), phosphorus (P), and potassium (K) concentrations increased linearly or quadratically with increasing fertilizer rates for all three fertilizers. In general, plants receiving 4-2-2 and 3-3-3 had higher concentrations of N, P, and K than plants receiving 14-14-14. Results from this study indicated that broiler litter-based 4-2-2 and 3-3-3 have the potential to be used as organic fertilizer sources for container production of marigolds in greenhouses. However, growers need to be cautious with the rate applied. Because different crops may respond differently to these natural fertilizers, it is important for growers to test any new fertilizers before incorporating them into their production practices.

Abstract:
Biogeochemical cycling of phosphorus in the agro-ecosystem is mediated by soil microbes. These microbes regulate the availability of phosphorus in the soil. Little is known about the response of functional traits of phosphorus cycling microbes in soil fertilized with compost manure (derived from domestic waste and plant materials) or inorganic nitrogen fertilizers at high and low doses. We used a metagenomics investigation study to understand the changes in the abundance and distribution of microbial phosphorus cycling genes in agricultural farmlands receiving inorganic fertilizers (120 kg N/ha, 60 kg N/ha) or compost manure (8 tons/ha, 4 tons/ha), and in comparison with the control. Soil fertilization with high level of compost (Cp8) or low level of inorganic nitrogen (N1) fertilizer have nearly similar effects on the rhizosphere of maize plants in promoting the abundance of genes involved in phosphorus cycle. Genes such as ppk involved in polyphosphate formation and pstSABC (for phosphate transportation) are highly enriched in these treatments. These genes facilitate phosphorus immobilization. At a high dose of inorganic fertilizer application or low compost manure treatment, the phosphorus cycling genes were repressed and the abundance decreased. The bacterial families Bacillaceae and Carnobacteriaceae were very abundant in the high inorganic fertilizer (N2) treated soil, while Pseudonocardiaceae, Clostridiaceae, Cytophagaceae, Micromonosporaceae, Thermomonosporaceae, Nocardiopsaceae, Sphaerobacteraceae, Thermoactinomycetaceae, Planococcaceae, Intrasporangiaceae, Opitutaceae, Acidimicrobiaceae, Frankiaceae were most abundant in Cp8. Pyrenophora, Talaromyces, and Trichophyton fungi were observed to be dominant in Cp8 and Methanosarcina, Methanobrevibacter, Methanoculleus, and Methanosphaera archaea have the highest percentage occurrence in Cp8. Moreover, N2 treatment, Cenarchaeum, Candidatus Nitrososphaera, and Nitrosopumilus were most abundant among fertilized soils. Our findings have brought to light the basis for the manipulation of rhizosphere microbial communities and their genes to improve availability of phosphorus as well as phosphorus cycle regulation in agro-ecosystems.

Abstract:
Phosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed that P losses of above fertilizers had significant differences (P &lt; 0.05) compared with control. P losses order arranged by Duncan test showed as total P (TP): SM &gt; OF &gt; OC &gt; CF &gt; BS &gt; CK, total dissolved P (TDP): SM &gt; OF &gt; BS &gt; CF &gt; OC &gt; CK, and particulate P (PP): OC &gt; SM &gt; OF &gt; CF &gt; BS &gt; CK. Concentrations of all the phosphorus forms increased with the increased rainfall. The ratio of TDP to TP gradually decreased after fertilizer application, and PP gradually increased. PP was the dominant form in surface runoff. Organic fertilizers had more P losses than inorganic fertilizers, even though both of them had obvious P losses.
