Abstract: Optimum plant density of soybean varies with geographic location and variety. The present study was undertaken with a view to optimize plant density of two soybean varieties using equidistant planting patter to obtain higher yield. The experiments were conducted in three consecutive seasons viz., Rabi 2004-05, Kharif 2005 and Rabi 2005-06 at Mymensingh, Bangladesh with two soybean varieties G-2 and PB-1 and six plant densities viz., 20, 40, 60, 80, 100 and 120 plants m-2 established using an equidistant planting pattern of 22.4×22.4 cm, 15.8×15.8 cm, 12.9×12.9 cm, 10.0× 10.0 cm and 9.1× 9.1 cm, respectively. Seed yield increased with increase of plant density up to 80 to 100 plants m-2 depending on variety and season. The increase in plant density decreased yield components such as number of pods plant-1, seeds pod-1 and 100-seed weight as well as seed yield plant-1. The soybean seed yield was positively correlated with total dry matter and leaf area index. The present study concludes that the highest soybean yield could be possible with a plant density of 80-100 plants m-2 depending upon variety, season and related agronomic management options.
