Abstract
Most of soybean varieties in Indonesia are indeterminate type, and the yield is lower as compared with soybean yield of Japan. In this paper, the growth and flowering characteristics of Indonesian indeterminate soybean were analyzed in response to drought and different date-planting. Indonesian indeterminate varieties showed a long-vegetative growth even under the optimum photoperiod, a high productivity in grain number and a tolerance to drought. In view of the results, it was suggested that Indonesian indeterminate soybean varieties had a high yielding potential for soybean production in the tropics.
