The experiment was carried out to study the influence of planting space and fertilizer application levels on some agronomic characters and yield in newly released semi-dwarf soybeans, Paldalkong and Dankyungkong. The number of branches per plant was not reduced by planting space form 60 X 10 cm 30 x 15 cm. These Semi-dwarf soybeans had good adaptability on high planting density. The number of pods per node on the main stem was different according to the planting space in Dankyungkong, but it was similar in Paldalkong except planting space 20 X 10 cm. Regardless of planting densities and varieties, the number of grains per pod on upper node of the main stem was large. Coefficient of variation of pods and grains per node in the middle part of the main stem was small. The number of grains per plant was decreased in high planting density compared to low planting density, but the number of harvested plant per unit area was increased. Optimum planting space was 25 X 10 cm in both varieties. The ability of nodulation was bigger in Dankyungkong than in Paldalkong
