Abstract
Defoliation effect of two soybean cultivars on the grain yield was studied under different planting densities planted at two different planting date. Leaf removal caused a linear decrease of grain yield with increased amounts of defoliation in the case of lower population densities, while in the case of higher population densities over 40 plants per sqare meter, the slight removal of lower leaves indicated increased grain yields by 13% to 35% compared with control depending on the cultivar and planting time. The pod number per plant was the most effective factor influencing grain yield. The grain weight and the percent of matured grain become more important components for higher yield with decreased population densities depending on cultivar.
