Green soybean as fresh vegetable is gaining popularity in many of the soybean-producing countries of the world. Soybean as vegetable can be grown easily during rainy season because final product is harvested as immature green seed (Shanmugasundaram et al., 1982). Decapitating at 4-5 trifoliolate leaves has been found to increase the yield by 14 to 22% (Tin, 1982).
