Abstract

In mixed cropping patterns as in agroforestry systems, competition between crops and trees will occur. It will specifically occur for nutrient absorption and light for photosynthetic process, which often has a negative impact on crop productivity. Field trial approach was used to examine adaptation of soybean varieties to shade in each tree, namely: rubber, mindi, white teak, jabon, sentang. The test is done with a Split plot design. The main plot is type of shading while subplots are soybean varieties. Treatment composition in the first experiment on each factor (main plot and subplot) and type of plant is consisted of: Main plot: P1 = Rubber shading, P2 = Mindi shading, P3 = Jabon shading, P4 = White Teak shading. Subplot: V1 = Anjasmoro variety; V2 = Burangrang variety, V3 = Dena-1 variety, V4 = Dena-2variety. The finding of the research were: 1) Shading as the main plot have very significant effect on plant high except at 3 weeks after planting (MST), has very significant effect on flowering age of soybean; 2) The effect of shading types on leaf chlorophyll parameters, both in the leaf tip, middle leaf, base leaf and total chlorophyll is identical. Mindi, Jabon and white teak stands did not have significant effect each other, but all three stands affect the chlorophyll content of soybean leaves compared to rubber stands, where the levels of soy chlorophyll under this stand were the lowest.
