Field experiments were conducted to study the premise that multiple cropping with rainfed rice depends on rapid establishment of good stand and on the efficiency of the selected crop to perform under increasing soil moisture stress. Five crops, namely sweet corn (PH 801), sorghum (Cosor 2), soybean (CES 434), mongo (CES 14), and sweet potato (BNAS) were grown under three soil moisture regimes: at 6 inches deep from the surface, level 1, 48.8%; level 2, 46.4%, and level 3, 23.5% and at 12 inches deep from the surface, level 1, 48.5%; level 2, 46.4%; and level 3, 32.1%, to study growth and yield performance of each crop under soil moisture stress. Results showed that in level 3, performance in general including crop yield, was lower than that at levels 1 and 2.
