In order to assess responses of soybean cultivars, a field experiment was conducted at research station of Islamic Azad University, Kermanshah province, Iran. The yield of soybean under water stress conditions was dependent largely on maturity group. Regular irrigation resulted in significantly increased soybean production, in both early as well as late maturity groups. Late maturity group was most sensitive to water stress.
