Efforts to increase soybean productivity must be synergy with the improvement of soil fertility through fertilizer, especially organic fertilizer. Population density of a crop determines to a greater extent its performance in terms of soybean yield. Based on the two cultivation techniques mention above, that is expected to increase soybean productivity. The objective of this research was to obtain organic fertilizer and plant spacing that can support the development of early-medium maturity soybean (Lokal Jateng soybean lines/Sinabung-1036) to achieve 3 ton dry seed per hectare. The research was conducted at Alfisol soil Muneng Station Research, Probolinggo and at Entisol soil Genteng Station Research, Banyuwangi on dry season (DS) 2012. The experiment used split plot design with three replications. As the main plot was plant spacing, namely: 1) 40 cm x 10 cm, 2 plants/hole, 2) 40 cm x 15 cm, 2 plants/hole, 3) 40 cm x 20 cm, 1 plant/hole, and 4) 40 cm x 20 cm, 2 plants/hole. As the sub plot were four doses and types of organic fertilizer, namely: 1) without organic fertilizer, 2) 2.5 t manure/ha, 3) 5 t manure/ha, and 4) 2 t Santap NM-2/ha. The result showed that the potential yield of 3 t/ha for large, early-medium maturity soybean could not be achieved at Alfisol soil Probolinggo and at Entisol soil Banyuwangi by planting soybean of Lokal Jateng soybean lines/Sinabung-1036 with plant spacing 40 cm x 10-20 cm, 1-2 plants/hole and application of 2.5-5 t manure/ha or 2 t Santap NM-2/ha.

Application of organic fertilizer can maintain and improve physical, chemical, and biological soil fertility and plant productivity. However, the use of manure requires a long time and a relatively large amount to have a positive impact on the soil and plants. In this regard, a study was carried out to evaluate the effect of the application of organic fertilizer and NPK inorganic fertilizer on soybean in lowland Vertisol. The study was conducted in lowland Vertisols in Ngawi and Madiun. The experiment used a randomized block design with three replications, with combination treatments of cow and chicken manure, Santap NM1 and NM2 fertilizer, and Phonska. The soybean seed used in this research was Local Central Java/Sinabung-1036 soybean line. The results showed that in lowland Vertisol of Ngawi which is rich in P element, application of 5,000 kg of cow manure/ha, 3,000 kg of chicken manure/ha, 1,500-2,500 kg/ha Santap NM1 and NM2 fertilizers, and 300 kg of Phonska/ha is not required. The yield of Local Central Java/Sinabung-1036 soybean line reached 1.95 t/ha. The lowland Vertisol of Madiun which has poor P element requires the addition of 5,000 kg of cow manure/ha, 1,500-2,500 kg/ha of Santap NM2 fertilizer, and 150 kg of Phonska/ha to increase soybean yield by 21-27% (0.42-0.55 t/ha). The quality and productivity of soil and crop cultivation in sustainable agriculture can be maintained by alternative recommendations for the use of organic and inorganic fertilizer inputs.
Abstract. Lestari SAD, Sutrisno, Kuntyastuti H. 2017. Short Communication: Effect of organic and inorganic fertilizers application on the early-medium maturing soybean yield. Nusantara Bioscience 10: 1-5. 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.
Its early maturity and drought resistance allows mungbean to be cultivated on upland with dry climate. Approriate cultivation technology need to be identified in order to increase productivity. The research objective was to formulate cultivation technology package by assessing interaction between plant population, optimum organic and anorganic fertilizers on mungbean. This experiment was conducted on upland Alfisol soil with type E climate in Probolinggo, East Java on dry season 2015, using split plot design, with three replications. As the main plot was plant spacing, namely: 1) 40 cm x 10 cm, 1 plant/hole, 2) 40 cm x 15 cm, 2 plants/ hole, and 3) 40 cm x 20 cm, 2 plants/hole. As the sub plot was combination of organic and anorganic fertilizers, namely: 1) without fertilizer, 2) 50 kg ZA + 50 kg SP36 + 100 kg KCl/ha, 3) 150 kg Phonska/ha, 4) 5 ton manure/ha, and 5) 75 kg Phonska + 2,5 ton manure/ha. Medium dose of NPK fertilizer (22,5 kg N + 22,5 kg P 2 O 5 + 22,5 kg K 2 O + 15 kg S) per ha and plant population of 250.000 until 333.333 plant per ha, was considered suitable to grow mungbean at upland with dry climates, based on the obtained yield. While low dose of NPK fertilizer (11,3 kg N + 11,3 kg P 2 O 5 + 11,3 kg K 2 O + 7,5 kg S) plus 2.500 kg manure/ha was capable of producing high biomass of mungbean up to 3,2 kg/ha.
Abstract. Putri PH, Susanto GWA, Artari R. 2017. Response of soybean genotypes to salinity in germination stage. Nusantara . Salinity is one of the agricultural problem, especially in marginal land. The negative impact of salinity for plants such as delay germination time, growth inhibition, reduce nodules formation, decrease biomass accumulation, and reduce yield quantity and quality. Initial selection for salt resistance of soybean, conducted on 16 genotypes, using three levels of NaCl and three replications. Germination conducted for six days, in germinator which has been set at 25 o C, with lighting. Mean Germination Time (MGT), Final Germination Percent (FGP), sprout length (root and overall) and weight (fresh and dry), seedling vigor index (length and weight) were observed. Data were analyzed using ANOVA, followed by LSD at 5%. Sixteen soybean genotypes show inhibition effect of salinity. The results showed that 125 mM NaCl does not inhibit germination but it causes abnormal growth at some genotypes. Number of normal germination decreased 20-30% at 125 mM NaCl. Sprouts total length declined by 17-58% at 75 mM and 45-78% at 125 mM NaCl. Root length decrease from 23.2-55.3% at 75 mM and 52.1-81.2% in 125 mM. Fresh weight diminish by 3.8-39.9% at 75 mM and 12.7-52.5% at 125 mM NaCl. Response of sixteen soybean genotypes into salinity stress is clearly visible at sprout length and fresh weight variable. Ichiyou was salt-sensitive based on all variable especially sprout length and fresh weight, while Baluran was salttolerant up to 125 mM NaCl based on sprout length and fresh weight.
Kuntyastuti H, Lestari SAD. 2017. Application of manure and NPK fertilizer on Grobogan variety and Aochi/W-C-6-62 soybean as promise line in lowland Vertisol Ngawi, Indonesia. Nusantara Bioscience 9: 120-125. The effort to increase the productivity and production of soybean in lowland can be done with application of organic and/or inorganic fertilizer combined with promise line or large seed size soybean varieties that have high yield potential. Application of manure can increase soybean seed yield, but it needs a very high dose of more than 10 t manure/ha, so that often inhibits the supply, transportation, and application. The objective of this research was to evaluate the application of manure and NPK fertilizer on large seed size soybean which is Grobogan variety and Aochi/W-C-6-62 soybean as promise line in lowland Vertisol. The research was conducted in lowland Vertisol Ngawi on dry season (DS) 2011. The experiment used factorial randomized complete block design with three replications. The first factor was four doses of manure and the second factor was four doses combination of NPK fertilizer. The result showed that, on Vertisol soil Ngawi, Grobogan variety soybean need 2.5 t manure/ha to increase yield from 1.65 t/ha to 1.84 t/ha. To get a high yield of Aochi/W-C-6-62 soybean as promise line, there is two options fertilization. Aochi/W-C-6-62 need 7.5 t manure/ha to increase yield from 1.76 t/ha to 2.05 t/ha without inorganic fertilizer. Aochi/W-C-6-62 need 50 kg ZA + 150 kg SP-36 + 50 kg KCl/ha, but does not require additional manure to achieve 2.05 t/ha.
The objective of this research was to determine the residual effect of fertilizer and former plant spacing of mungbean first planting on growth and yield of cowpea second planting in a dry land. The experiment was conducted at Muneng Research Field, Probolinggo, East Java during dry season in 2015. The cowpea seeds of KT 5 varieties were planted in plots measuring 4 m x 4,5 m with plant spacing of 40 cm x 15 cm, 2 plants/hole. This research was carried out without adding fertilizer (fertilizer application only given on mungbean planting). This experiment was laid out in a split plot design and replicated three times. Plant spacing of mungbean as the main plot, namely 1) former of 40 cm x 10 cm, 1 plant/hole (J1); 2) former of 40 cm x 15 cm, 2 plants/hole (J2); and 3) former of 40 cm x 20 cm, 2 plants/hole (J3). Residual combination of organic and inorganic fertilizers as the sub plot, namely 1) former without fertilizer (R0); 2) former of 50 kg ZA + 50 kg SP-36 + 100 kg KCl/ha (R1); 3) former of 150 kg Phonska/ha (R2); 4) former of 5000 kg organic fertilizer/ha (R3); and 5) former of 75 kg Phonska + 2500 kg organic fertilizer/ha (R4). The results showed that the cultivation of cowpea with R3 and R4 treatments had effects on shoot and roots dry weights. The highest cowpea yield was obtained with J3 and R4 treatment of 1,62 t/ha and the highest biomass was obtained with J3 treatment of 5,92 t/ha, but statistically not significantly different from the other treatments.
