Yield and water use efficiency (WUE) increased significantly with LCDI compared to HWon cucumber (13 and 41%), sponge gourd (85and 129%), eggplant (38 and 113%), bitter gourd (121 and 35%) and long bean (5 and 27%) respectively. Yield and WUE of cucumber (22 and 25%) and long bean (9% and 12%) increased with FBDP compared to CCF. Net income due to FBDP was greater by 24 and 14% for cucumber and long bean, respectively, compared to CCF. The number of man-days employed for irrigation increased six times in HW compared to LCDI. Net return with LCDI was greater by 52% compared to HW and varied from 4 to 121% between the crops. (This is a shortened version of the abstract.)
