title: The effect of lime of dolomite and NPK fertilizers on the response of growth, yield and protein content on black soybean (Glycine soja L.Merr) in acid soils
abstract: The development of cultivation from plant black soybeans (Glycine soja (L. Merr. in the acid soils can be an alternative to increase the yield of black soybean plants. However, the utilization of acid soils is plagued by soil pH value, high content of Al, Mn, and Fe as well as low availability of macro elements N (nitrogen) P (phospor) K (potassium) Ca (calcium) and Mg (magnesium) This study aims to determine the effect of dose of lime dolomite and NPK fertilizers on the response of growth, yield, and protein content of plant black soybeans on acid soils. This research used Complete Random Design (CRD) consist of 2 factors, each factor consists of 4 levels. The dose of lime dolomite 4,5 tons/ha was able to produce the highest total dissolved protein content amounted 4,30% while giving the lime of dolomite and NPK fertilizers showed significant results in plant's height, weight of fresh pods, weight of seeds/plant, number of seeds/plant, weight of 100 seeds, dry weight of stover, and dry weight of roots.

title: Growth and Yield of Soybean as a Response of the Fertilization of NPK Compound Produced with Spent and Deoiled Bleaching Earth Filler
abstract: Spent Bleaching Earth (SBE) is a by product of the refining of Crude Palm Oil (CPO) into cooking oil which is classified as hazardous and toxic materials waste. SBE has the potential to be used as a filler in the production of NPK fertilizer. This study aims to compare the effect of SBE and Deoiled Bleaching Earth (DBE) as the replacement of clay mineral, which is expected to have the same effect as the control treatment in terms of the leaf area, total dry weight, plant height and yield of plant. This experiment used a one factor Randomized Complete Block Design (RCBD) with three replicates. The treatments of filler in NPK fertilizer were 10% clay minerals, NPK with 5% clay mineral 5% SBE filler and NPK with 5% clay mineral 5% DBE filler. Fertilizer was given twice, ie when the plant was 14 days after planting (DAP) as much as 2 g polybag 1 and age 35 DAP as much as 3 g polybag 1 at each treatment. The results showed that the application of NPK fertilization with 5% clay mineral 5% SBE filler and NPK fertilization with 5% clay mineral 5% DBE filler had the same effect as NPK fertilization with 10% clay mineral filler on leaf area, total dry weight, plant height and yield of plant. SBE and DBE can be used as subtituties for clay mineral in NPK fertilizer production.

title: Growth and Yield Responses of Four Soybean (Glycine max (l. Merrill. Cultivars to Different Methods of NPK Fertilizer Application
abstract: This study aimed to determine the growth and yield responses of four soybean cultivars to different methods of N, P, and K fertilizers application. The methods consisted of one time application (at the planting time) and split application (at the planting time and during the initial stage of pod formation (R3 stage) Four superiors soybean cultivars were used, namely Anjasmoro, Grobogan, Dena 1, and Argomulyo. One time fertilizers application resulted in an increased plant height compared to split fertilizers application. In contrast, the split fertilizers application led to a higher yield of soybeans indicated by the higher total number of pods, number of filled pods, 100 grain weight, and seed dry weight. Cv. Anjasmoro produced higher growth and yield than cv. Grobogan, Dena 1, and Argomulyo. It also produced the highest yield compared to other cultivars. Meanwhile, cv. Argomulyo produced the lowest yield in both fertilization methods. Based on the soil analysis after harvest, the nutrient content of K in the soil was higher than before planting in both fertilization methods. In addition, the split fertilizers application led to higher utilization of P in the soil after harvest.

title: Effect of Three Levels of NPK Fertilizer on Growth Parameters and Yield of Maize Soybean Intercrop
abstract: Field experiments were conducted at the Teaching and Research Farm, University of Agriculture, Makurdi to determine the effect of three levels of NPK fertilizer on growth parameters and yield of maize soybean intercrop. The experimental design consisted of two factors: cropping system at two levels (sole and intercrops) and NPK fertilizer at three levels (0, 150 and 300 kg/ha of NPK 20:10:10) The treatments were laid out in a Randomized Complete Block Design (RCBD) in a split plot arrangement and replicated three times. The cropping systems were assigned to the main plots while the fertilizer levels were in the sub plots. A composite soil sample was obtained from a plough layer (0 15 cm) at the beginning and at the end of the experiment and analyzed for particle size distribution, pH, organic carbon, total nitrogen, available phosphorus and exchangeable cations [Mg, Ca, Na and K] as well as cation exchange capacity (CEC) Data collected for the yield and growth parameters of maize and soybean were subjected to the Analysis of Variance (ANOVA) after which significant means were separated using Least Significant Difference (LSD) at p<0.05. From the results, application of fertilizer significantly (p<0.05) increased the growth parameters and yield of the component crops in both seasons. Increasing the quantity of NPK fertilizer resulted in significant increase in the yield and growth parameters of maize and soybean in both years. Intercropping resulted in yield advantage in 2013 and 2014 showing 35 and 26 land saved respectively. Also, from the results and productivity advantage obtained from the intercropping, the effect of different rates of NPK fertilizer on the growth and yield of maize and soybean intercrop deserve further investigation using higher fertilizer rates.

title: Effect of liming, manure, and NPK fertilizer application on growth and yield performance of soybean in swamp land
abstract: Increased productivity and the expansion of planting area to potential land are two strategies to increase soybean production. Swamp land is one of potential land. Acidic soil, poor fertility, and toxicity become limiting factors for soybean development in this area. Objective of this research was to determine effect of liming, organic and NPK fertilizer application on soybean yields in swamp land. On farm trial had been conducted on swamp land of C type in South Kalimantan. Treatments consisted of two factors, laid out in randomized complete block design, replicated three times. The fist factor was three doses of manure (0, 2.5, and 5.0 t/ha) The second factor was four combinations of NPK fertilization dosage, (1) 0 0 0, (2) 22,5 36 30, (3) 22,5 54 60, and (4) 45 72 60 kg N P 2 O 5 K 2 O per hectare. Combinations of these two factors were tested on two environments, without and with liming. Results revealed that soil acidity, poor P, K, Ca, and Mg, and high aluminum saturation became limiting factors for soybean growth and yield in swamp land of type C in South Kalimantan. Amelioration using 2.5 t/ha manure, liming with dolomite equivalent to 20% of Al saturation, and NPK fertilizer at dose of 45 kg N 72 kg K 2 O 60 kg P 2 O 5 /ha improved soil properties and soybean growth, and increase productivity to 2.4 t/ha.

title: Effects of Biofertilizer Produced from Bradyrhizobium and Streptomyces griseoflavus on Plant Growth, Nodulation, Nitrogen Fixation, Nutrient Uptake, and Seed Yield of Mung Bean, Cowpea, and Soybean
abstract: The use of biofertilizers is important for sustainable agriculture, and the use of nodule bacteria and endophytic actinomycetes is an attractive way to enhance plant growth and yield. This study tested the effects of a biofertilizer produced from Bradyrhizobium strains and Streptomyces griseoflavus on leguminous, cereal, and vegetable crops. Nitrogen fixation was measured using the acetylene reduction assay. Under N limited or N supplemented conditions, the biofertilizer significantly promoted the shoot and root growth of mung bean, cowpea, and soybean compared with the control. Therefore, the biofertilizer used in this study was effective in mung bean, cowpea, and soybean regardless of N application. In this study, significant increments in plant growth, nodulation, nitrogen fixation, nitrogen, phosphorus, and potassium (NPK) uptake, and seed yield were found in mung beans and soybeans. Therefore, Bradyrhizobium japonicum SAY3 7 plus Bradyrhizobium elkanii BLY3 8 and Streptomyces griseoflavus are effective bacteria that can be used together as biofertilizer for the production of economically important leguminous crops, especially soybean and mung bean. The biofertilizer produced from Bradyrhizobium and S. griseoflavus P4 will be useful for both soybean and mung bean production.
