Soybean genetic resources with high yield potential and supported by good crop management are expected to increase soybean productivity. In Indonesia until 2021 there are 105 soybean varieties that have been released by Indonesian Ministry of Agriculture with potential yields 1.0-3.8 t/ha. A study has been conducted to obtain high yield soybean genetic resources and different planting methods so that it can improve growth and increase productivity to achieve yield >3.0 t/ha. The research was conducted at 2018 in.Kendalpayak research station, Malang, East Java, Indonesia. The experimental design was split-plot with three replications, where the main plot was planting methods (double row and single row) and the sub plot was soybean genotype (15 genotypes/accessions from ILETRI collection). Plant growth, light intensity, seed yield and yield components were measured to determine the effect of treatment. Results showed that there was variability of response each genotype to different planting methods. The planting method was significantly affected by light intensity and plants biomass at pod filling stage, while accessions were significantly affected by light intensity, plant growth, and yield components. Based on productivity per hectare there were 9 accessions no. 2, 3, 5, 6, 8, 9, 11, 13, and 15 which have the opportunity to produce soybean productivity above 3.0 tons/ha, with planting double rows of 50 cm x (30 cm x 15 cm) or single row of 40 cm x 15 cm. The use of double row spacing of 50 cm x (30 cm x 15 cm) can increase soybean productivity by 11% compared to the single row of 40 cm x 15 cm.
