Food Commodity

Rice is the primary food commodity in Indonesia. To increase the rice production, urea fertilizer has been excessively used, specifically on marginal land. However, it has no desired effect on the plant’s Nitrogen uptake due to volatilization. Previous studies suggest the use of zeolite to be mixed with urea to reduce the volatilization rate. This study aimed to determine the effect of six NP-SR (Nitrogen Phosphorus Slow Release) fertilizer compositions (without NP-SR; 20.69-0; 19.7-5; 17.27-10; 15.9-15; and 18.94-20) on soil chemical properties, nitrogen efficiency, and paddy rice yield on Ultisols at three waterlogging levels (0.5 cm, 3 cm, and 5 cm). The study was an experiment arranged in a Randomized Complete Block Design (RCBD) consisting of two factors, which were waterlogging levels and NP-SR fertilizer compositions. The results showed that waterlogging treatments significantly affected soil chemical properties in the initial vegetative and harvest phases. It can be concluded that the treatment of flooding (up to 3 cm) and fertilizer (NP-SR of 15.90-15) application could significantly reduce the volatilization rate, increase the efficiency of N fertilizer, and increase rice yield.

During integrated nutrient management involving poultry manure (PM) and urea fertilizer (UF) for maize (Zea mays L.), it is necessary to investigate the best time to apply UF that will optimize soil chemical properties, growth, and yield of maize. Hence, studies were carried out to investigate the effect of different rates of PM and single and split applications (SA) of UF on soil chemical properties, growth, and yield of maize. The treatment involved three levels of PM (0.0, 4.0, and 8.0 t·ha−1) and four sets of periods of UF: (i) 0 kg N ha-1 (control), (ii) 120 kg N ha-1 applied at planting (AP), (iii) two SA of 120 kg N ha−1 (90 kg N ha-1 applied AP + 30 kg N ha-1 at thirty days after planting (DAP)), and (iv) three SA of 120 kg N ha-1 (60 kg N ha-1 applied AP + 30 kg N ha-1 thirty DAP + 30 kg N ha-1 at tasseling). The 12 treatments were arranged in a randomized complete block design and replicated three times. PM and UF alone and integrating UF with PM improved soil chemical properties, growth, and yield of maize compared with the control. SA of UF three times (60 + 30 + 30) had the most improved soil chemical properties, growth, and yield of maize. Results also showed that maize yielded higher under UF integrated with PM compared with their sole forms. Application of 60 + 30+30 with 8 t ha−1PM (60 + 30+30 + 8 t ha−1PM) or with 4 t ha−1PM treatments showed the highest growth and yield of maize, but due to the bulkiness, handling challenges, and cost of PM, 60 + 30+30 + 4 t ha−1PM is recommended. Therefore, for better growth and yield of maize, after the initial application of PM, UF application should be split-applied in accordance with plant growth and the pattern of uptake to avoid losses by leaching and therefore ensured that N level in the soil is high at the critical stage of N demand.

Background: Since N fertilizer applied to maize (Zea mays L.) is prone to loss by leaching, it is important to derive an application time during the phenology of maize when the fertilizer is most efficiently and effectively used by the crop with minimal losses. Objective: Hence, experiments were carried out in 2014 at two locations in Osogbo southwest Nigeria to determine the effects of split application of N fertilizer on soil chemical properties, maize performance, and profitability. Methods: The treatments were: (i) control, (ii) 120 kg N ha-1 Applied at Planting (AP), (iii) two split applications (SA) of 120 kg N ha-1 {90 kg N ha-1 applied AP + 30kg N ha-1 at thirty Days After Planting (DAP) [90 + 30]}, and (iv) three SA of 120 kg N ha-1 {60 kg N ha-1 applied AP + 30 kg N ha-1 thirty DAP + 30 kg N ha-1 at tasselling[60+30+30]}. The four treatments were arranged in a Randomized Complete Block Design with three replicates. Results: Results indicate that at both sites, SA three times (60+30+30) has the most improved soil chemical properties, growth and yield of maize relative to other methods. The yield parameters increased in the order: control < 120 kg N ha-1 applied once < 90+30 < 60+30+30. Using the mean of both sites, 60+30+30 increased yield of maize by 15.3%, 37.1% and 138.2%, respectively compared with 90+30, 120 kg N ha-1 applied once and the control. Optimum returns were recorded by 60+30+30 with net return of ₦ 227,600 and a benefit cost ratio of 3.67:1 while the application of 120 kg N ha-1 applied once has a return of ₦ 157,200 with a benefit ratio of 2.9. These results show that farmers would benefit by making more profit by adopting the method of SA of N fertilizer three times (60+30+30). Conclusion: Therefore, for improved soil chemical properties, growth, yield and profitability of maize, N fertilizer application should be structured in accordance with this pattern of uptake to avoid losses by leaching and therefore ensure that N level in the soil is high at the critical stage of N demand.

Increasing domestic soybean production is an important part of the effort to reduce reliance on imports. One potential area for improvement is developing soybean crops in Alfisols. Alfisols require intensive effort due to their poor soil chemical properties. Manure and zeolite were proposed as candidate materials that could be used to improve soil chemical properties to support plant growth and increase the productivity of cultivated land. The experiment was designed to study the addition of manure and zeolite on soil chemical properties of Alfisols and soybean yield. The experimental design was arranged in a factorial completely randomized block design with two factors—three rates of zeolite (Z0 = 0 t ha<sup>-1</sup>, Z1 = 2.5 t ha<sup>-1</sup> and Z2 = 5 t ha<sup>-1</sup>) and three manure variables (P0 = no manure, P1 = 5 t ha<sup>-1</sup> cow manure, and P2 = 5 t ha<sup>-1</sup>  quail manure)—with three replications. The results showed that a combination of 5 t ha<sup>-1</sup> zeolite and cow manure increased soybean yield. However, zeolite 5 t ha<sup>-1</sup> resulted in the greatest improvement in soil chemical properties—the highest CEC, soil organic matter percentage, and pH.

An experiment to study the effect of cow urine applications and dosage of N fertilizer was conducted in Bondowoso, from February to April 2002. A factorial experiment consisted of two factors and the whole treatments were arranged in 3x4 factorial Randomized Complete Block Design (RCBD) with 3 replications. The first factor was urine of Cow, consist of U0 = control, U1= 20%, U = 40%. The second factor was dosage of N fertilizer, consist of N1 = 0 kg/ha, N2 = 150 kg/ha, N3 = 300 kg/ha, N4 = 450 kg/ha. The effect of treatments on growth and yield of cucumber were observed. The result showed that there was no interaction between cow urine application and dosage of N fertilizer, except to the fruit diameter. Cow urine application significantly improved the yield of Cucumber, and the 40% application gave the best fruits weight. Dosage of N fertilizer significantly increased the growth and yield of cucumber, and the 450 kg N-fertilizer/ha had the better effects.

ABSTRACT<br /><br />The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500  kg of manure.<br /><br />Keywords: Al saturation, chemical properties of soil, nutrient uptake, produktivity, soil amelioran

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

Application of right dosage of fertilizer and concentration of plant growth regulator are supporting factor of clove growth. This study was aimed to obtain the best combination of organic-inorganic fertilizer, the best triacontanol concentration and both interactions for increasing clove growth. This study used a Randomized Complete Block Design (RCBD) with two factors. The first factor was the organic-inorganic fertilizer dosage package that consisted of 6 levels, i.e no fertilizer, 100% recommended dosage of inorganic fertilizer (r.d.i.f), 25% recommended dosage of organic fertilizer (r.d.o.f) + 75% r.d.i.f, 50% r.d.o.f + 50% r.d.i.f, 75% r.d.o.f + 25% r.d.i.f, 100% r.d.o.f. The second factor was the concentration of triacontanol that consisted of 3 levels, i.e no triacontanol, 2 mg L-1 and 4 mg L-1. The results showed that the application of 25% r.d.o.f + 75% r.d.i.f produced the best clove growth, but it was not significantly different from the combination treatment of the two other types of fertilizer as indicated by the greatest improvement on stem diameter, branches number, leaf area, chlorophyll a, chlorophyll b, total chlorophyll and carotenoids. Clove plants did not respond to the application of triacontanol at a concentration of 2 mg L-1, but gave a negative response to the application of triacontanol 4 mg L-1 on the plant height and leaf area variables. The interaction of the two factors did not have significant effects on all variables. Keywords: chlorophyll, morphology, nutrient dynamics, physiology, vegetative growth
