Abstract

Background: Light is one of the environmental factors that greatly affect the growth and yield of crops in general, including soybean plants. The purpose of this study was to determine the effect of shade on yield and yield components of soybean varieties. Methods: The research method was a randomized complete block design (RCBD) with three replications. The first factor was the kind of variety which consisted of two levels, i.e., Dena I and Anjasmara. The second factor was the level of shading, which consisted of four levels, i.e., 0, 10-20, 20-30 and 30-40%. Result: The results showed that shade decreased the number of filled pods, dry pod weight per plant, 100 seeds weight and seed yield ha-1. As the shade increases, the lower the yield and component of soybean yields increases. The decrease in seed yield ha-1 of Dena I variety at 10-20, 20-30 and 30-40% shade was 22, 14 and 50%, respectively, while the Anjasmara variety was 9, 49 and 59%. Shade decreases yields and yield components of Dena I and Anjasmara varieties. In the higher level of shade, the yield reduction will increase.
