Harahap SM, Ramija KE, Erythrina E. 2020. Yield response of peanut (Arachis hypogaea L.) to compound fertilize. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 41-49.The purpose of this study was to evaluate the application effects of three different compound fertilizers on yield, and assess the income increase at different rates of compound fertilizers. Three compound fertilizers namely NPK 14-0-46, NPK 19-9-19 and NPK 11-11-11 was conducted at three different farmers’ field in Langkat District, North Sumatra Province under upland conditions. In each farmers’ field, a Randomized Complete Block Design was applied with four replications per treatment. Seven treatments tested consisted of full rate of farmer fertilizer practice and six rates of each compound fertilizer plus half rate of farmer fertilizer practice. In each of compound fertilizer tested, pod yield and seed yield increased quadratically as increasing compound fertilizer rates. The highest pod yield and seed yield of peanut were 1649 kg/ha and 1072 kg/ha, respectively with half rate of FFP + 200 kg of NPK 14-0-46. For compound fertilizer NPK 19-9-19 the highest pod yield and seed yield were 1632 kg/ha and 1032 kg/ha with half rate of FFP + 500 kg of NPK 19-9-19 while for compound fertilizer NPK 11-11-11 the highest pod yield seed yield were 1421 kg/ha and 930 kg/ha with half rate of FFP + 250 kg of NPK 11-11-11. However, adding each half rate of farmer fertilizer practices with 200 kg of NPK 14-0-46 or 300 kg of NPK 19-9-19 or 250 kg of NPK 11-11-11 with HypoMa-1 cultivar gave the highest values of the benefit for the farmers under upland soil in Langkat, North Sumatra.

<p>The aim of this experiment was to compare the influence of organic and inorganic fertilizers on selected indicators of turf growth-production process under non–irrigated conditions. The experiment was carried out in warm and dry conditions in the area of Nitra (Slovak Republic). In the experiment were included 5 treatments: 1.Without fertilization, 2. Turf NPK fertilizer 15–3–8 (+3 MgO +0.8 Fe +18 S), 3. Slow release NPK fertilizer 14–5–14 (+4 CaO +4 MgO +7 S), 4. Organic NPK fertilizer 5-1-1 and 5. Organic NPK fertilizer 3-2-1. Determination of the average height of turf, total height of turf and the annual average daily gain of height showed that best treatment was application of slow release fertilizer. Turf fertilized by Organic NPK fertilizer 5-1-1 reached the highest values of the average height of turf, total height of turf and the annual average daily gain of height, the same as treatment without fertilization. These finding were statistically significant. Treatment without fertilization reached the lowest values in evaluated growth-production parameters.</p>

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.

Orchid fertilization is fundamental for a satisfactory plant growth and development for commercial orchid production as well as in collections. Mineral and/or organic sources can be used for fertilization. The objective of this study was to evaluate the effect of the use of organic and/or mineral fertilizers on the nutrition and growth of orchid (Laelia purpurata 'werkhanserii' x L. lobata 'Jeni') seedlings in greenhouse. The following fertilizers were tested: an NPK fertilizer + micronutrients; a Ca source in the form of calcium nitrate; two organic fertilizers, one prepared with a mixture of bone meal, castor meal and ash, and a similar commercial fertilizer. The organic fertilizers were distributed on the surface of the pots every two months and the minerals were applied weekly to the substrate in 25 mL aliquots of a solution containing 1 g L-1 of the respective fertilizer. The plant response to the application of mineral together with organic fertilizer was better, with higher dry matter production than by the isolated application of each fertilizer (organic or mineral). The treatments with calcium nitrate + NPK fertilizer did not differ significantly from the use of NPK fertilizer, probably due to the S deficiency detected in a mineral analysis of the tissues. Commercial organic fertilizer had a very elevated B level, leading to toxicity symptoms, reduced growth and necrotized tips of the older leaves in all fertilized treatments.

Increasing P availaibility can be done using Phosphate solubilizing microorganism, but available information about indigenous phosphate solubilizing microorganism utilization from paddy soil that intensively fertilized with P is limited. The objectives of this experiment were to isolate, to select and to test the potential of phosphate solubilizing fungi (PSF) in increasing P availability, P uptake and rice production. Five isolates of PSF, referred to A1, A2, A3, A4 and A5 isolates, were belong to the Aspergillus genera. Field experiment was arranged in a randomized block design with one factor and 3 replications. The treatments consisted of 11 combinations of PSF and NPK fertilizer, i.e., without PSF + 100% rate of NPK fertilizer; PSF A1 + 50% rate of NPK fertilizer; PSF A1 + 100% rate of NPK fertilizer; PSF A2 + 50% rate of NPK fertilizer; PSF A2 + 100% rate of NPK fertilizer; PSF A3 + 50% rate of NPK fertilizer; PSF A3 + 100% rate of NPK fertilizer; PSF A4 + 50% rate of NPK fertilizer; PSF A4 + 100% rate of NPK fertilizer; PSF A5 + 50% rate of NPK fertilizer; PSF A5 + 100% rate of NPK fertilizer. Experiment results showed that application of PSF isolates increased P availaibility, P uptake, rice growth and rice production significantly. Application of PSF A1 + 50% rate of NPK fertilizer was the best treatment as indicated by the increased in weight of 1,000 rice grains, P availaibility and P uptake

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.

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.

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.

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).

Full textAbstract:
Effects of herbicide and herbicide-fertilizer combinations on vegetative and reproductive growth of the lowbush blueberry (Vaccinium angustifolium Ait.) were assessed over a 12-yr period (six production cycles). All treatments stimulated stem lengths, fruit buds per stem and fresh fruit yields compared with untreated controls, but only after 3–6 yr. After the second cycle, stem lengths and fruit bud numbers were greater in herbicide + NPK-treated plants than in all others. Fresh fruit yields were variable throughout the study but were higher in herbicide and herbicide + fertilizer plots than in untreated controls after 1982, except in 1988. Nitrogen levels were greater in leaves and rhizomes of plants in all herbicide and herbicide + fertilizer plots than in control plots after 10 yr, whereas phosphorus was higher only in plants fertilized with NPK. These results suggest the lowbush blueberry responds slowly to herbicide and fertilizer applications. Increased vegetative and reproductive development, as well as denser plant stands, resulted from repeated herbicide and fertilizer applications. Fertilizers applied in conjunction with herbicides stimulate vegetative growth (and fruit buds if an NPK fertilizer), but appear to have no consistent effect on fresh fruit yields. Key words:Vaccinium angustifolium, fertilizer, herbicide, fruit buds, yield

The use of inorganic fertilizers has been reported to have improved pasture productivity, however it has also attributed to soil toxicity, environmental pollution, mineral imbalance, and health hazards among many adverse effects. This made the adoption of organic fertilizers became best alternative to correct nutrients deficiencies in the soil due to their environmental friendly nature and less cost effectiveness. To investigate the comparative advantages of these two types of fertilizer, an experiment was conducted to evaluate the influence of fertilizer types on the nutritive quality of Panicum maximum var. Ntchisi and Andropogon tectorum harvested at 6 and 8 weeks during the wet season. The study was a factorial experiment (4 x 2 x 2), arranged in a split-split-plot design with three replicates. There were 16 treatments to include; fertilizer types (NPK, Aleshinloye organo-mineral fertilizer, poultry manure and control (no fertilizer)), grass species (Panicum maximum var. Ntchisi and Andropogon tectorum) and age at harvest (6 and 8 weeks). Fertilizer treatments were allotted to the main plots while grass species were allotted to sub-plots and again harvest age was allotted to sub-subplots. Sub-samples taken from harvested forage materials were oven dried, properly milled and analysed in the laboratory to determine proximate composition [crude protein (CP%), ash, ether extract (EE%)], fibre fractions [acid detergent fibre (ADF%), neutral detergent fibre (NDF%), acid detergent lignin (ADL%), Cellulose, and Hemicelluloses) and in vitro gas production. Fertilizer types significantly (P<0.0.5) affected ADF, hemicellulose, cellulose and methane (CH4). The grasses fertilized with NPK had the highest value (9.00mL) for CH4. Poultry manure (PM) fertilized grasses recorded the highest value for in vitro dry matter digestibility (IVDMD) (89.38%). Andropogon tectorum fertilized with PM harvested at 6 weeks recorded the highest value for IVDMD (93.00%) and the same grass fertilized with NPK, harvested at 6 weeks recorded the highest values (0.37 mL and 4.70%) for short chain fatty acid and metabolizable energy, respectively. Therefore, this study established that fertilizer applications had an influence on fibre fraction, methane and post-incubation parameters of the grasses investigated.

Many have reported that application of Silicon (Si) can alleviate environmental stress and increase grain yield of maize plants under stresses. This study aimed to examine the effects of adding organic or silicate fertilizer on several varieties of maize in rainfed area during a dry season, by conducting field experiment designed with Randomized Complete Block Design testing two treatment factors, i.e. maize varieties (V1= Bisi-2, V2= Srikandi, V3= Pioneer-27) and fertilizer combinations (F1= NPK only, F2= NPK+organic, F3= NPK+silicate). Results indicated that there were significant effects of fertilizer combinations and varieties on growth and yield of several maize varieties, in which the mean values were highest in maize plants fertilized with NPK+silicate fertilizers, except harvest index. Among the varieties, Pioneer-27 (hybrid) yielded the highest followed by Srikandi (open-pollinated) and Bisi-2 (hybrid) yielded the lowest grain weight per plant. However, there were interaction effects of the treatment factors, meaning that there were different responses between varieties of maize to application of organic or silicate fertilizer in addition to NPK fertilizer in terms of plant height, AGR (average growth rate) of plant height and dry grain yield per plant. Grain yield per plant of Pioneer-27 could be increased with application of organic (150.79 g/plant) or silicate (189.43 g/plant) compared with NPK only (133.99 g/plant), while that of Srikandi and Bisi-2 could only be increased by addition of silicate (113.83 g/plant in Srikandi and 103 g/plant in Bisi-2) compared with NPK only (93.77 g/plant in Srikandi and 82.59 g/plant in Bisi-2).

This study was an attempt to determine the effect of different combinations of manure and fertilizers on the yield of rape crop so as to improve yield by recommending the best combination of manure and fertilizers to the rape growers in Botswana. Rape crop was planted on farmers field in a complete randomized block design where nine different combinations of manure and fertilizers, namely, chicken manure (Ch); Ch and NPK (2:3:2); Ch and Fe (Iron); Ch, NPK and Fe; Ch and Urea; Ch, NPK and Urea; Ch, Urea and Fe; Ch, NPK, Urea and Fe; and control (No application of manure and fertilizer) were considered. Each fertilizer combination was replicated four times in a total of thirty six plots in the layout of the experiment. The data on rape yield was collected. The leaves of rape were harvested three times a month and the rape yield (in kg) was recorded in a harvest sheet. A two way analysis of variance (ANOVA) was performed using the SPSS software. The results indicated that fertilizer combination of chicken manure, NPK and Urea produced the highest yield of rape which was 2.61 times higher than the yield produced by the control plots (where no manure and fertilizer was applied) and therefore, a fertilizer combination of chicken manure, NPK and Urea was recommended to the rape growers. Suggested future studies included the comparative profitability of different fertilizer combinations as well as the effects of different doses of the organic and inorganic fertilizers on rape production.

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.

Oil palm (Elaeis guineensis Jacq.) holds a very strategic role in the Indonesia economy. Plants that have reached the economical age of 25 years need to be replanted using qualified oil palm seedling. The qualified seedling is obtained through proper fertilization. The combination of NPK fertilizer and organic material of oil palm empty fruit bunches (OPEFB) which has been given a cellulolytic bacterial consortium can provide sufficient nutrients for the growth of oil palm seedlings. The study aimed to determine the effect of giving a combination of OPEFB organic material, cellulolytic bacterial consortium, and NPK fertilizer on the growth of oil palm seedling (Elaeis guineensis Jacq.) at main nursery. This experiment used a single factor experiment arranged in a Completely Randomized Design (CRD). The treatments were a 100% NPK, a OPEFB compost, a 50% NPK + OPEFB compost, a 50% NPK + OPEFB + Cellulolytic bacterial consortium, and a OPEFB + cellulolytic bacterial consortium. The results showed that the application of inorganic fertilizers combined with organic fertilizers (a OPEFB compost and a OPEFB + cellulolytic bacterial consortium) had a good effect on each parameter. Giving organic fertilizer without inorganic fertilizer had not affected plant growth on all parameters. Application of a OPEFB compost and a OPEFB + cellulolytic bacterial consortium can reduce the use of inorganic fertilizers by 50%.

ABSTRACT The effects of mineral fertilizer (NPK) and organic manure on the community structure of soil ammonia-oxidizing bacteria (AOB) was investigated in a long-term (16-year) fertilizer experiment. The experiment included seven treatments: organic manure, half organic manure N plus half fertilizer N, fertilizer NPK, fertilizer NP, fertilizer NK, fertilizer PK, and the control (without fertilization). N fertilization greatly increased soil nitrification potential, and mineral N fertilizer had a greater impact than organic manure, while N deficiency treatment (PK) had no significant effect. AOB community structure was analyzed by PCR-denaturing gradient gel electrophoresis (PCR-DGGE) of the amoA gene, which encodes the α subunit of ammonia monooxygenase. DGGE profiles showed that the AOB community was more diverse in N-fertilized treatments than in the PK-fertilized treatment or the control, while one dominant band observed in the control could not be detected in any of the fertilized treatments. Phylogenetic analysis showed that the DGGE bands derived from N-fertilized treatments belonged to Nitrosospira cluster 3, indicating that N fertilization resulted in the dominance of Nitrosospira cluster 3 in soil. These results demonstrate that long-term application of N fertilizers could result in increased soil nitrification potential and the AOB community shifts in soil. Our results also showed the different effects of mineral fertilizer N versus organic manure N; the effects of P and K on the soil AOB community; and the importance of balanced fertilization with N, P, and K in promoting nitrification functions in arable soils.

Soil chemical and biological properties affected by 21-year application of composted manure with chemical fertilizers in a Chinese Mollisol. Can. J. Soil Sci. 92: 419–428. The effects of 21-yr of application of chemical fertilizers, composted pig manure (CPM) alone, and chemical fertilizers combined with compost on soil chemical and biological properties were investigated. Soil samples (0–20cm) were collected from a long-term fertilization experiment under corn (Zea mays L.) production in 2006, prior to seeding, at the corn tasseling stage and following harvest. Fertilizer treatments were: no fertilizer (CK), nitrogen fertilizer alone (N), N + phosphorus (NP), N + P + potassium (NPK), CPM, N + CPM, N + P + CPM (NP + CPM), and N + P + K + CPM (NPK + CPM). Long-term application of N alone resulted in a reduction of soil pH by 0.38 units and reduced the available P concentration compared with CK. An increase in soil pH was seen with CPM alone and NPK + CPM. Both fertilizers sources, singly and combined, increased the total N and available N concentrations. Total P and total K concentrations were greatest with the NPK + CPM treatment. All fertilizer treatments increased the soil organic carbon (SOC), light fraction organic carbon (LFOC) and microbial biomass carbon (MBC) concentrations significantly (P < 0.05) at the tasseling stage. The NPK + CPM treatment showed the greatest increase in SOC (12%), LFOC (78%) and MBC (44%) concentrations, compared with CK. Soil enzyme activities (invertase, urease, acid and alkaline phosphatases) tended to be greater at tasseling than other sampling dates, with highest enzyme activities in the NPK + CPM treatments. These findings suggest that a long-term application of CPM combined with NPK is an efficient strategy to maintain or increase soil quality in Mollisols for sustainable agriculture.

Balangu (Lallemantia sp.) is a medicinal herb with a variety of applications, all parts of which have economic uses, including leaf for extraction of essential oils, as a vegetable and potherb, seed for extraction of mucilage and edible or industrial oil. To investigate the effect of cultivation season and standard chemical and nano fertilizers (n) on the yield components and antioxidant properties of Dragon’s head, a factorial experiment based on randomized complete block design was conducted with 12 treatments and three replications. Experimental treatments consisted of two seasons (spring and winter cultivation) and six levels of fertilizer (control, NPK-s, NPK-n, Fe-chelated-n, NPK-n + Fe-chelated-n, NPK-s + NPK-n + Fe-chelated-n). The traits included grain yield per plant, essential oil percentage and yield, mucilage percentage and yield, antioxidant properties in the seeds and leaves, including total phenols and flavonoids content, DPPH radical scavenging, and nitric oxide and superoxide radical scavenging. The results showed that winter cultivation had a noticeable advantage over spring cultivation across all of the traits. The highest grain yield per plant was obtained in winter cultivation using NPK-n + Fe-chelated-n fertilizer treatment. The highest essential oil percentage was in NPK-n + Fe-chelated-n. The highest mucilage percentage was observed in NPK-s + NPK-n + Fe-chelated-n fertilizer treatment, which was not statistically different to NPK-n + Fe-chelated-n treatment. The combined effects of winter cultivation and NPK-n + Fe-chelated-n fertilizers resulted in improving antioxidant activity traits. Overall, the results indicated that the combination of winter cultivation and NPK-n + Fe-chelated-n fertilizers are the most appropriate treatment to acquire highest qualitative and quantitative yield of Dragon’s head, in the Azerbaijan region (Iran).

A field experiment was conducted during 2010-2011 and 2011-2012 to investigate the effect of optimal (100% NPK) to super-optimal doses (200% NPK) of mineral fertilizers on soil enzymes such as dehydrogenase (DHA), acid phosphatase (Ac-PA), alkaline phosphatase (Alk-PA), fluorescien diacetate hydrolysis (FDA), urease and nitrate reductase (NRA) at three physiological stages (CRI, anthesis and maturity) of wheat crop on an Inceptisol. Dehydrogenase activity was reduced by 28-37% when fertilizer application was at super-optimal dose (200% NPK), whereas, urease and NRA responded positively in the range of 43-44% and 213-231% respectively. Alk-PAwas 7.3-7.9% higher in treatments receiving 125% NPK as compared to control (100% NPK); whereas, Ac-PA declines in the plots receiving 175 and 200% of recommended dose of fertilizer (RDF) as compared to 150% NPK levels. Addition of 175% RDF increased the FDA to the tune of 46-53% as compared to 100% NPK. A significant (P≤0.05) positive interaction between fertilizer treatments and physiological stages of wheat growth was observed on soil enzyme activities (except urease and NRA) being highest at the anthesis stage of wheat. Correlation matrix analysis showed that DHA was correlated with the studied enzyme activities except Ac-PA and FDA; whereas, strong correlation was observed between urease and NRA (r=0.981, P=0.01). This study provides theoretical and practical base for avoiding super optimal application of fertilisers which hinders the enzyme activities and vis-a-vis sustainable nutrient enrichment under rhizosphere.

<p>Rate of NPK fertilization on rice using NPK compound fertilizer needs to consider soil nutrient status and plant nutrient requirement. The research was aimed to determine the optimum rate of compound fertilizer and the effect of enriched S nutrient of NPKS compound (15-15-15-5S) and NPK compound fertilizer (15-15-15) on the growth and yield of rice. The experiments were conducted at two sites in Galuga, Ciampea Bogor, West Java from April to September 2013, using randomised complete block design with 3 replications. Experiment at site I consisted of 9 treatments: six levels of fertilizers NPKS i.e. 0; 150; 300; 450; 600; and 750 kg/ha, standard fertilizer, NPK compound fertilizer equivalent to standard, and standard fertilizer plus S. Rate of urea, SP-36, and KCl for standard fertilizer treatment was respectively 250, 75, and 50 kg/ha. At site II the treatments consisted of 6 levels of NPK compound fertilizer i.e. 0; 150; 300; 450; 600; and 750 kg/ha and the standard fertilizer with rate of 250 kg/ha of urea, 50 kg/ha SP-36, and 75 kg/ha KCl. Plot size was 4 m x 5 m planted with Ciherang variety. Data collection included chemical properties of soil before and after the experiment, plant height, number of tillers, straw weight, and dry grain weight and the nutrient uptake. The effectiveness of fertilizer was calculated by RAE (Relative Agronomic Effectiveness). Results showed that fertilizer NPKS (15-15-15-5S) at 600 kg/ha effectively increased dry grain weight from 3.63 t/ha to 4.67 t/ha, but was not significantly different from a standard fertilizer treatment. It increased dry grain weight by 29% compared to control. NPK fertilizer (15-15-15) effectively promoted growth and dry grain weight equivalent to standard fertilizer at rate of 300-750 kgha. The optimum rate of NPK compound fertilizer (15-15-15) was 440 kg/ha as was shown with the production performance of 4.12 t/ha with RAE by 58%. NPKS compound fertilizer with rate of 750 kg/ha showed the highest uptake of N, P, and K nutrients and significantly increased the available P in the soil. Whereas NPK compound fertilizer with a rate of 600 kg/ha indicated the highest P nutrient uptake. Fertilizer enrichment with sulfur on NPKS fertilizer (15-15-15-5S) did not significant affect on grain dry weight.</p>

<p>The need of nitrogen (N), phosphate (P) and potassium (K) nutrient in oil palm nursery are usually fulfilled with synthetic chemical fertilizers such as NPK fertilizer. The application of NPK fertilizer can cause the soil to become hard due to the accumulation of the residue left on the ground. Cow manure is able to substitute NPK fertilizer based on the chemical status of the soil. This study aimed at analyzing the effect of NPK fertilizer substitution with cow manure on the growth of oil palm seedlings in the pre-nurseries and main nurseries. The experiment was conducted from February to September 2018 in the Banguntapan research and experimental field, Faculty of Agriculture, Universitas Gadjah Mada. The experiment applied the Randomized Complete Block Design (RCBD) with one factor and six blocks as replications. The factors were subtitution using the replacement series method with five levels of doses, 100% NPK, 75% NPK + 25% cow manure, 50% NPK + 50% cow manure, 25% NPK + 75% cow manure and 100% cow manure. The observed parameter variables were root lenght, root area, hump diameter, leaf area, the number of leaves, plant height and plant dry matter. The use of 25% NPK substitute with 75% organic material was the best result in increasing the growth performance of oil palm seddlings in pre-nursery and main nursery.</p>

<p>ABSTRACT</p><p>Degradation of soil fertility due to inaccurate application of fertilizer become one of the factors causing the stagnant rice productivity improvement in Indonesia. Straw incorporation, organic fertilizers and biofertilizers applications potentially reduces a rates of inorganic fertilizers and improves soil fertility. The aim of this study was to evaluate growth and yield of 3 lowland rice varieties (high yielding variety, new plant type, and local variety) in response to reduce NPK rates with straw incorporation, organic fertilizer, and biofertilizer in 7th planting season. The research was conducted at rice field in Karawang, West Java, from April-August 2013. The research was arranged in split plot randomized block design with 3 replications. The main plot was fertilizer application consisted of 10 treatments (combination of organic and inorganic fertilizers), while the sub plot was rice varieties (Ciherang, IPB 3S, and Mentik Wangi). The application of inorganic fertilizer, 400 kg NPK 30-6-8 ha-1, was control treatment. Plot size was 6.5 m x 10 m, with a double row spacing (25 cm x 15 cm x 50 cm). The result showed that growth of the three varieties was not significantly different so as the yield at 50% reduced NPK rate with incorporation of straw, organic fertilizer and biofertilizer. Adding of solid and liquid organic fertilizer, and biofertilizers on treatment of straw incorporation + 50% NPK rate was unnecessary due to insignificant yield increase.</p><p>Keywords: Ciherang, fertilizer, IPB 3S, local variety, Mentik Wangi, new plant type</p>

Indonesia is one of the largest crude palm oil (CPO) producing countries in the world. To improve oil quality, CPO purification is carried out including bleaching earth. The process produced spent bleaching earth (SBE) and deoiled spent bleaching earth (DSBE) classified as hazardous and toxic materials waste. SBE and DSBE have the potential as an adhesive material in the manufacture of NPK fertilizers. This study aimed to compare the effects of SBE and DSBE on replacing clay minerals in terms of biochemical response. The study was arranged in randomized completly block design with three treatments and blocks. The treatment consisted of NPK fertilizer containing 10% brown clay (control), NPK fertilizer containing 5% pure clay minerals + 5% SBE, and NPK fertilizer containing 5% pure clay minerals + 5% DSBE. Data were analyzed using ANOVA and tested using LSD test at a 95% confidence level. The results showed that NPK containing DSBE was able to increase nitrate reductase activity (NRA) (41.9%), chlorophyll b content (4.7%), glycine betaine (GB) (2.5%), decreasing electrolite leakage (19%), malondialdehyde (MDA) (23%) compared NPK containing brown clay. Thus the use of NPK containing DSBE and NPK containing SBE to be able to replace NPK containing brown clay.

Fecal sludge (FS) contains a significant amount of plant nutrients. FS (treated/untreated) has been used as soil ameliorant in several countries. Use of FS-based compost on lettuce may meet reservations due to possible microbiological contamination. The objectives of this research are: (1) To determine the fertilizer value of different formulations of sawdust and fecal sludge compost (SDFS) pellets, and (2) to compare the effect of these SDFS formulations with poultry manure, commercial compost, mineral fertilizer, and non-fertilization on lettuce cultivation. The SDFS products were made by enriching, and pelletized with ammonium sulphate, mineral-NPK, or ammonium sulphate + muriate of potash + triple superphosphate. Lettuce was cultivated in a greenhouse and an open field. The result showed that the saleable fresh weight lettuce yield obtained from all SDFS pellets with/without enrichments were higher than those obtained from commercial compost, poultry manure, mineral fertilizer, or no fertilizer. Cultivation in the open field gave higher yields than those in the greenhouse. No helminth eggs were detected in composts or lettuces. Some fecal coliforms were detected in lettuces fertilized with almost all fertilizers tested, including NPK and non-fertilized control. A properly treated fecal sludge-based fertilizer can be a sustainable solution for lettuce production, which helps urban and peri-urban agriculture.

Abstract The aim of this study was to determine the influence of various biological fertilizers on the growth and development of plants of the large-fruited cranberry and the degree of mycorrhizal association in their roots under controlled conditions. Plants of the ‘Pilgrim’, ‘Stevens’ and ‘Ben Lear’ cranberry cultivars were planted in rhizoboxes filled with soils collected from the areas of Krojczyn and Motoga. The following experimental treatments with fertilizers were applied: control plants, plants fertilized with NPK, a bacterial-mycorrhizal consortium, Vinassa, lignite + Vinassa, Florovit Natura and the fertilizer Crop-UP. The study has shown that there was a tendency to stimulate the vegetative growth and development of cranberry plants through the use of bio-fertilizers and beneficial fungi obtained from the rhizosphere of these plants. There was a tendency for the fresh and dry weight of cranberry shoots to increase, especially in ‘Ben Lear’, under the influence of the bio-fertilizer Florovit Natura when compared with the control plants fertilized with NPK. Compared with the NPK control, all of the bio-fertilizers significantly increased mycorrhizal frequency in the roots of the tested plants of the large-fruited cranberry, with the exception of Crop-UP and lignite compost used in conjunction with Vinassa in ‘Stevens’. No statistically significant differences were obtained for plant size and root colonisation by ericoid fungi in the plants grown in the soil from the areas of Motoga and Krojczyn.

Samples of Roselle plants were obtained from different soils (clay soil at Dar El-Ramad farm, sandy loam and saline loamy sand soil at Demo farm, Faculty of Agriculture) at El-Fayoum governorate conditions. Moreover, some of the phytochemical properties (N, P and K percentage in roselle herb and its uptake, photosynthetic pigments (chlorophyll A, chlorophyll B and carotenoids), anthocyanin pigment and pH value) of roselle plants (Hibiscus sabdariffa, L.) under different soils were determined. The data obtained showed that, bio and mineral (NPK) fertilizers increased the above compositions of roselle plants under different soils of experiment. The maximum increase of these compositions was obtained by the treatment clay soil × 100% NPK + bio fertilizers, followed by clay soil × 50% NPK + bio fertilizers as compared to saline loamy sand soil × non fertilizer treatment, although, the differences between these treatments and mineral fertilizer at the rate of 100% NPK alone were insignificantly. Therefore, it is economically and environmentally recommended to inoculate roselle seeds with mixture of Azotobacter + Bacillus and fertilize these inoculated plants with 50% NPK for improve chemical compositions (N, P and K percentage in roselle herb and its uptake, photosynthetic pigments (chlorophyll A, chlorophyll B and carotenoids), anthocyanin pigment and pH value) of roselle plants under clay soil.

Recovery of nutrients from source-separated urine can truncate our dependency on synthetic fertilizers, contributing to more sustainable food production. Urine-derived fertilizers have been successfully applied in soilless cultures. However, little is known about the adaptation of the plant to the nutrient environment. This study investigated the impact of urine-derived fertilizers on plant performance and the root-associated bacterial community of hydroponically grown lettuce (Lactuca sativa L.). Shoot biomass, chlorophyll, phenolic, antioxidant, and mineral content were associated with shifts in the root-associated bacterial community structures. K-struvite, a high-performing urine-derived fertilizer, supported root-associated bacterial communities that overlapped most strongly with control NPK fertilizer. Contrarily, lettuce performed poorly with electrodialysis (ED) concentrate and hydrolyzed urine and hosted distinct root-associated bacterial communities. Comparing the identified operational taxonomic units (OTU) across the fertilizer conditions revealed strong correlations between specific bacterial genera and the plant physiological characteristics, salinity, and NO3-/NH4+ ratio. The root-associated bacterial community networks of K-struvite and NPK control fertilized plants displayed fewer nodes and node edges, suggesting that good plant growth performance does not require highly complex ecological interactions in hydroponic growth conditions.

Biochar is a solid material produced by thermochemical conversion of biomass under oxygen-limited conditions. It has a wide surface and contains many pores so that it can be used as a material for making fertilizer. Biochar based slow release NPK fertilizer was formulated and developed to reduce nutrient leaching and greenhouse gas emissions. In this research, biochar which was a by-product of biomass gasification using oil palm empty fruit bunches was processed to make slow release biochar NPK fertilizer. Sources of nitrogen (N) were derived from urea, phosphate (P) from diamonium phosphate (DAP) and potassium (K) derived from potassium chloride (KCl). Zeolite was added as a matrix to improve fertilizer characteristics. All materials were formulated to make slow release biochar NPK fertilizer used for red onion (Allium sepa) plant applications. Several micronutrients were also added including Mg (MgSO4 fertilizer) and S (ZA fertilizer) to support plant growth. The characterization of fertilizer products was carried out by using SEM, BET etc. to determine physical properties including surface area, pore volume, morphology and composition. Furthermore, biochar NPK fertilizer was applied to the red onion plant which was a high-value crop in Indonesia. The application of NPK biochar fertilizer on red onion plant showed its superiority compared to commercial NPK fertilizers. In addition, the use of Magnesium and sulfur micronutrients could support the growth of red onion bulbs so that they produced more and bigger bulbs.Keywords: biomass, gasification, oil palm empty fruit bunches, biochar, slow release fertilizer*The paper has been selected from a collaboration with IPST and 7th ICFCHT 2019 for a conference entitled "Innovation in Polymer Science and Technology (IPST) 2019 in Conjunction with 7th International Conference on Fuel Cell and Hydrogen Technology (ICFCHT 2019) on October 16th - 19th at The Stones Hotel Legian, Bali, Indonesia"

Cultivation of okra on ultisol soils having poor physical, chemical and biological soil properties can be improved by administering a bio-stimulant extract of golden snails and combined with NPK fertilizer. This research objective was to study a combination of bio-stimulant treatment of golden apple snail extract and NPK fertilizer dosage in increasing the growth and yield of okra on ultisol soil. This study used a factorial completely randomized design with two factors. The first factor was Bio-stimulant golden apple snails extract consisting of 4 treatment, and the second factor was levels of NPK fertilizer consisting of 3 treatment. Fertilizers had a significant effect on increasing overall plant growth. The bio-stimulant extracts of golden apple snails contain organic materials that can improve physical properties (increasing aggregation, moisture retention, soil hydraulic conductivity), chemical (increasing soil organic carbon content) and biology (increasing soil microbial biomass). The nutrient content in NPK fertilizers can increase nutrients; the availability of nutrients in the soil is balanced and can be absorbed by plants so that the photosynthesis process in plants can run well and increase on growth and yield of okra. The combination of bio-stimulant extract of golden apple snails of 20 mL/L water and NPK fertilizer of 150 kg/ha (1 g/polybag) had the highest resulted in the average value of growth and yield of okra on the ultisol soils.

The research was performed in a pot experiment using a completely randomized factorial design with two treatment factors. The organic pellet fertilizer doses were: 0 ton ha-1 (a control); 10 ton ha-1; 20 ton ha-1; and 30 ton ha-1 as the first factor. In the second factor, the different NPK fertilizer dose was applied: the absence of NPK fertilizer as a control; 0.5 and 1 time of the recommended dose. The results showed that the application of organic pellet fertilizer significantly improved soil pH but not significant on soil organic C and N levels. There was tendency of increased on soil pH, C-organic, and N-total with the increased doses of organic pellet fertilizers applied. The NPK fertilizer application significantly improved plant height, tiller number and plant biomass as the dose were rised up. The organic pellet fertilizer application significantly improved plant height, number of tillers, and plant biomass. Applying organic pellet fertilizer at a dose of 10 tons ha-1 should be sufficient as no further improvement with the increasing doses.

Full textAbstract:
Crop residue management is a major concern in China. Returning straw to the field has been promoted to reduce chemical fertilizer input and increase crop yield. For this, the present study as a part of an existing long-term field experiment was conducted including four treatments: (1) Maize straw return with reduced nitrogen, phosphorus, and potassium fertilizers (straw + NPK; SNPK); (2) NPK fertilizers; (3) PK fertilizers; and (4) no fertilizers added (nF) in the years of 2016 and 2017. Results showed SNPK and NPK produced similar grain yield over the two years (12,485 vs. 12,754 kg ha−1), which was approximately 3-fold of PK and nF (4763 vs. 3858 kg ha−1). The yield difference was not significant between SNPK and NPK and between PK and nF. The effect of straw return on plant productivity is related to precipitation. In contrast to total carbon (C), nitrogen (N), and phosphorus (P), K was lost from leaf, stem, and grain. Dynamics of plant N post-flowering is critical to determine maize yield and yield components relative to C, P, and K. Dynamics of P and K in leaf were more correlated with yield than in stem, implying the significance of leaf productivity in determining grain yield. These results indicate that combination of NPK fertilizers is critical for increasing grain yield in maize. Crop straw return with reduced NPK fertilizers will help to improve yield and reduce chemical fertilizer input in the long run.

This fact shows that the use of NPK compound fertilizer can be recommended as a supplementary fertilizer to increase soybean growth and proudness. However, NPK compound fertilizer can also be used as a basic fertilizer if the availability of a single fertilizer N, P, and K is not available or more expensive with regard to the adequacy or dosage of its use.

Full textAbstract:
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.

Full textAbstract:
<p>One way to control or slow down the nutrient release rate from fertilizer is by coating technique. Nowadays the use of biodegradable coating materials for slow-release fertilizer (SRF) is preferable because of environmental issues. This research was aimed to make SRF using starches and cellulose as the coating materials and to test the release rate of the nutrients. Five kinds of starches (cassava, corn, sago, wheat, and glutinous rice) and carboxymethyl cellulose (CMC) were used as coating material for granulated NPK fertilizer. The coated fertilizers (NPK SRF) were tested for their leaching rate in the soil by percolation experiment. The results showed that the kind of starch used influenced the release rate of the NPK SRFs. The NPK SRF coated with sago starch exhibited slow release rate and low leached nutrients which also resulted in slow growth of corn plant, as expected of SRF. The use of starch and CMC as biodegradable coating materials in this research has a possibility to affect the microbial activity in the soil so that the nutrient release became faster than the uncoated NPK fertilizer.</p>
