Cultivars Naveen, Erramallelu, MTU 1010 and hybrid ARB17 (1) x 06 performed better both under aerobic and transplanted conditions. Rice cultivars received 426-570 mm of water under aerobic and 880-1057 mm under transplanted condition in addition to 200 and 180 mm of effective rainfall, respectively. The water productivity was higher under aerobic (0.20 to 0.60 kg/m³) than that under transplanted (0.14 to 0.43 kg/m³ of water) condition. 收起
