The experiment reported the morphological and physiological response of soybean varieties grown under different field capacity in sandy soil. Results indicated there was an interaction between soybean varieties and field capacity on days to flowering. Soybean varieties affect on plant height height (2 and 4 WAP), number of leaves (6 WAP), number of flowers, days to flowering, leaf greenness, leaf area index, number of stomata, number of openned stomata and stomata density. Meanwhile, field capacity influenced the number of leaves (4 and 6 WAP), number of branches (4 and 6 WAP), leaf area, number of flowers, days to flowering, leaf area index and seed weight per plant. Grobogan variety had the fastest flowering time (26 days after planting). In adiition, there were no significant differences among the soybean varieties in terms of seed weight per plant. Soybean grown in 100, 75 and 50 % FC had the highest seed weight per plant, while soybean grown in 25% FC had the lowest seed weight per plant. In conclusion, morphologically effects of drought stress of soybean took place when soybean grown at 50% FC and lower. Meanwhile, physiological responses of soybean to different in FC were resulted from changes in stomata density
