Efforts to increase soybean production require superior varieties which are stable in every agroecology production center. Therefore, it is necessary to perform field evaluation of several new released soybean varieties. The aim of this study was to evaluate the growth and yield potential of soybean varieties developed by Indonesian Legume and Tuber Crops Research Institute (ILETRI) Malang in a field experiment. Four soybean varieties (Devon 1, Dering 1, Gema and Gepak Kuning) were sown in Margodadi Village, Ambarawa Sub-district, Pringsewu Regency, Lampung Province, Indonesia from May to August 2017. Plots were arranged in randomized complete block design with six replicates. The variables observed were crop emergence at 7 DAS sowing, plant height and number of pods at harvest, pest attack on 1- month-old plants and at harvest, and seed yield. The results showed that Gepak Kuning gave the highest yield (2.13 t/ha), which indicated that this variety is suitable to be planted and developed in the location of the study.
