Efficient water management for improving productivity of rice - vegetable pea-summer maize system
Water management for rice - vegetable pea-summer maize productivity
Abstract
A filed experiment was conducted at ICAR Research Complex for Eastern Region, Patna Patna to evaluate rice - vegetable pea-summer maize production system under various water management practices. Results revealed that significantly higher grain (4047kg/ha) was produced when water was applied at W4 = (IW: CPE=1.0). Maximum irrigation water productivity (1.470kg/m3) was achieved when water supplied with (IW: CPE=0.4). In case of pea, significantly highest green pod yield (9.78/ha) was recorded in plots which was received water with W2 (IW: CPE=0.6). Highest irrigation water productivity (9.92 kg/m3) was achieved when pea was irrigated at IW: CPE=0.4. Whereas, maximum (18.41t/ha) maize green cob was harvest when it was manage with W4 (IW: CPE=1.2. In case of water management, highest irrigation water productivity (6.25kg/m3) was achieved when pea was irrigated at IW: CPE=0.8).
