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.

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.

Full textAbstract:
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.

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%.

[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..

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.

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

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.

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.

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.

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<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

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.

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%.

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.

Eight species of edible flowers were grown in 12.5-cm (1.5-L) square containers during the months of November through May, in a root medium suitable for organic certification or a standard peat and perlite mixture with preplant fertilizer. Plants were fertilized with 200 mL of either a water-soluble fertilizer (19–1.8–19) at 300 ppm N, fish emulsion (5–0.4–0.8), or a certified organic, commercially available soluble fertilizer (6–2.6–5), each at 300 or 600 ppm N applied every 2 weeks. Shoot fresh and dry weights were measured and percent dry weight was calculated. The fresh weights for all species were highest for plants fertilized with the organic fertilizers. For all but one species the organic fertilizer treatments had the same or higher dry weights than the inorganic control. The percent dry weights for all species were the same or higher for the inorganic control treatment. The effect of the organic fertilizer rate on the dry weight was species-dependent. The highest flower production generally occurred with 300 ppm N. Flower size was measured for Viola tricolor and Viola ×. wittrockiana species. For both species flower size was smallest for plants fertilized with the 600 ppm certified organic fertilizer. Root media pH and EC were tested at 6-week intervals throughout the experiment. In general, the pH increased from the first to the second sampling date, but only increased or decreased slightly for later dates, and there was little effect of fertilizer type. Root media EC decreased initially with minimal change later.

<p>Indonesian Agency for Meteorology Climatology and Geophysics Agency (BMKG) stated that the implementation of CFS program can increase the production significantly up to 30% (BMKG 2016). This research was conducted to know the influence of climate field school (CFS) and fertilizer dosage on soil chemical properties and corn yield. The study was conducted with a nested experimental design with two factors. Factor A has two levels: CFS Program (S1) and nonCFS (S2) and factor B was fertilizer dose. Factor B is nested on factor A as A (B). The fertilizer dose factor consists of 6 levels; T0 (without fertilizer); T1 (100% organic fertilizer); T2 (75% organic + 25% inorganic fertilizer); T3 (50% organic + 50% inorganic fertilizer), T4 (25% organic + 75% inorganic fertilizer), T5 (100% inorganic fertilizer). The results showed that CFS program increased available P, available K and soil pH, while fertilizer dose (50% organic fertilizer + 50% inorganic fertilizer) on CFS program yielded the highest soil organic matter (4.12%). CFS and fertilizer dose both did not affect the yield of maize significantly. However, the average yield of maize on CFS land is greater (6.50 tonha<sup>-1</sup>) compared to nonCFS (5.38 tonha<sup>-1</sup>). The treatment with 100% inorganic fertilizers) on CFS program gives highest yield (8.75 tonha<sup>-1</sup>).</p>

Full textAbstract:
The present investigation aims to evaluate the impacts of organic and inorganic fertilizers on the water parameters and physiological behaviors of an aquatic plant (Azolla sp.). The experiment used three groups: treatment with organic or inorganic fertilizer and a group with no fertilization as a control. Azolla sp. were grown in cement ponds that received different treatments. For water analysis, the obtained results clarified that fertilization resulted in no variation in the temperature or total hardness among different treatments. Organic fertilizer increased the dissolved phosphorus content, total hardness, and bicarbonate alkalinity, as well as the total phosphorus content, whereas inorganic treatment increased the pH, total ammonia content, and total nitrogen content. Regarding the biochemical composition of Azolla sp., the chlorophyll content showed no variation among different treatment groups, while organic matter showed high variation among different treatment groups. The highest values for ash and fat content were recorded in control ponds. The highest protein content was found in organic treatment ponds. The addition of fertilizers led to an increase in the tissue contents of N and P compared to the control. This increase was highest when Azolla sp. was fertilized with organic fertilizer. The atomic N:P ratio was low in tissues subjected to either treatment compared with the control. The doubling time of Azolla sp. was decreased by fertilization. It is concluded that different fertilizer systems have significant effect on physico-chemical and biological parameters of water. Fertilization positively affects Azolla sp. growth. Organic fertilizer was more efficient for the growth of Azolla sp., so it can be considered as a source of biofertilizer and green manure in areas where it spreads.

Full textAbstract:
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.

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 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.

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound

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.

Balancing nutrient inputs from manure and supplemental inorganic fertilizers with crop requirements should achieve crop yield goals and agro-environmental targets. We asked if composted dairy cattle manure, alone or in combination with inorganic fertilizers, could sustain the corn and soybean yields, without increasing the residual soil nitrogen (N) and soil phosphorus (P) saturation of a sandy-loam soil in southern Quebec, Canada. Cropping systems were continuous silage corn and corn–soybean rotation, with each phase of the rotation grown every year, for 5 yr. Cropping systems were amended with compost at rates of 0, 15, 30, and 45 Mg (wet weight)·ha−1, and they received supplemental inorganic fertilizer to supply 200 kg N·ha−1·yr−1 to corn while assuring that corn and soybean received 45 kg P·ha−1·yr−1 and 125 kg potassium (K)·ha−1·yr−1 from compost and inorganic fertilizer. Crop yields were similar in compost-amended and inorganically fertilized plots. Corn yield was limited by N availability, and there was no P or K limitation in corn and soybean. Soil P saturation in the 0–15 cm layer exceeded the agro-environmental limit of 13.1% P/Al for a sandy-loam soil in Quebec, indicating that the P input exceeded crop uptake. Residual soil N concentration was affected more by the crop than the fertilizer source, with greater residual soil N in plots with higher grain production. Crop-induced priming can explain how N fertilizer cycles through the soil microbial community and is gradually mineralized during the growing season, and why crop senescence may trigger residual soil N release after harvest.

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.

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.

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.

<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>

Tuberose (Polyanthes tuberosa L.) is a potential flowering plant that will be developed in Jatinangor, West Java, Indonesia. However, the characteristics of Typic Hapludult soil in Jatinangor , i.e. clay texture, acidic pH, and high amount of total-P but low in available-P cause the tuberose difficult to grow optimally. The aim of this study was to obtain the potential ratio of organic and inorganic fertilizer dosages for tuberose grown on Typic Hapludult. The combinations of organic and inorganic fertilizers with different ratios (0/0; 0/1; 1/0; 0.5/0.5; 0.5/1; 1/0.5; 1/1.5; 1.5/0; 1.5/0.5, and 1.5/) were applied. The application of the combination of organic and inorganic fertilizers showed positive effects on soil pH, available-P, total-P, and fresh weight of tuberose grown on Typic Hapludult. The application of 50% organic fertilizer + 50% inorganic fertilizer was an effective combination that was able to increase the fresh weight of tuberose up to 9240 g plant-1 or increasing the fresh weight by 39% in comparison to that in the control treatment (without fertilizer application).

This study aimed to determine growth and yield of two varieties of peanut in a 2:2 replacement series intercropping system with black rice under aerobic irrigation system on raised-beds. The experiment, carried out on irrigated rice fields in South Kediri village (West Lombok, NTB) from May to August 2019, was arranged according to Split Split-Plot Design with three treatment factors, namely intercropping system as the main plots (T1: intercropping 2:2 rows between peanuts and black rice; T2: peanut monocrop), peanut varieties as the sub-plots (V1: Bison; V2: Hypoma-1 variety), and combinations of inorganic-organic-bio-fertilizers for black rice as the sub-sub-plots (P1: NPK fertilizer only; P2: NPK+Petroganik; P3: NPK+Petroganik+mycorrhiza bio-fertilizer). The intercropped peanut was fertilized only with 200 kg/ha Phonska (NPK). The results indicated that the most influencing treatment factors were intercropping systems and combinations of inorganic-organic-bio-fertilizers. However, there were significant two-factor-interactions, namely between varieties and intercropping systems on peanut leaf number, dry stover weight and dry filled-pod weight, and between intercropping systems and fertilizer combinations on seed yield and harvest index. Dry seed yields were not significantly different between varieties, but were higher under P3 (21.17 g/clump) or P2 (20.67 g/clump) compared to P1 (19.35 g/clump), while peanut intercropped with black rice resulted in higher seed yield (22.10 g/clump) than monocroped peanuts (18.69 g/clump). Based on the interaction between intercropping systems and fertilizer combinations, the highest seed yield was obtained in peanuts intercropped with black rice fertilized with NPK+organic+bio-fertilizer (23.65 g/clump) and the lowest average was in monocropped peanuts (17.87 g/clump).

Indigenous vegetables are plant species that are of great nutritional and medicinal importance. In a bid to ensure their domestication, availability and consumption, it is necessary to investigate their response to fertilizer treatment and other suitable agronomic practices that will enhance their cultivation and nutritional composition. In this study, an experiment was carried out to determine the effect of organic and inorganic fertilizers on the growth and yield of Solanum macrocarpon. The experiment was laid out in a Complete Randomized Design with four treatments: NPK 200 kg /ha, - T1, Poultry manure 6t/ ha - T2, NPK and Poultry manure 100 kg/ha + 3 t/ha - T3, Control, No Fertilizer - T4. Leaf area, plant height, number of leaves, and stem diameter were measured using standard methods. Proximate and mineral analyses were also carried out in accordance with standard chemical methods. The growth and yield of S. macrocarpon was improved by fertilizer application. All growth parameters measured increased with plant age and significant differences (p < 0.05) were observed among the treatments. Results obtained from this study also highlighted the potential of poultry as an alternative source of Nitrogen required for plant growth. Although both organic and inorganic fertilizers improved the growth performance of the vegetable, yet, the inorganic fertilizer produced the best results for all the parameters studied. Inorganic (NPK) and organic (Poultry manure) fertilizer increased soil fertility and improved the nutritional composition, but Solanum macrocrapon plants grown with inorganic fertilizer performed better.

Full textAbstract:
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.

The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. 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).

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.

The cultivation of carambola produced some waste that can be used as organic fertilizer. Organic fertilizer is useful to improve soil conditions and enrich the nutrient content contained therein so that it is easily absorbed by cultivated plants such as pakcoy (Brassica rapa L.). The optimum pakcoy production is supported by good land management in order to meet the availability of nutrients needed by the addition of inorganic fertilizers and starfruit organic fertilizer.

Fertilizer is one factor that is very influential in the success of agriculture. There are two types of fertilizer circulating in Indonesia today that is organic fertilizer and inorganic fertilizer (chemical). The used of chemical fertilizers allows the distribution of natural radionuclides into the environment. This study was conducted to determine the risk of the radioactive index of chemical fertilizer in Indonesia using gamma-ray spectrometry. There are 6 types of samples of fertilizers ie urea, ZA, KCL, NPK, TSP, and Phosphate. Radioactive risk index value that is found in the overall sample of fertilizer is below the limit recommended by the ICRP.

Chili is one of the most important spices in Indonesia; the demand for chili is increasing along with the growth of the population. Chilli is generally grown under intensive culture which includes addition of fertilizers to improve crop growth and increase crop productivity. A study was conducted to examine seven different rates of an inorganic foliar fertilizer HF at 0.5, 0.75, 1, 1.25 and 1.5 of the recommended rate, with no foliar fertilizer and a standard foliar fertilizer GD as control. The results showed that spraying foliar fertilizer HF generally improved the growth and yield of chilli compared to without fertilizer. Plant height, number of branches and number of fruits per plant, weight per fruit, weight per 10 fruits, yield per plant, yield per plot, and yield per ha of chilli treated with inorganic fertilizers was significantly higher than the without foliar fertilizer. Foliar fertilizer HF at 0.5 of the recommendation rate, or 1 kg.ha-1 foliar fertilizer applied at 4, 6, 8, 10, and 12 week after planting in addition to the basic fertilizers of 400 kg.ha-1 of urea, 200 kg.ha-1 of SP-36, 250 kg.ha-1 of KCl applied to the soil, was effective to obtain the maximum chilli fruit yield.

Full textAbstract:
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.
