The impacts of deficit irrigation on rice and winter wheat were examined using lysimeter experiments, in terms of water requirement, irrigation water, yield response, water use efficiency and crops' minimum soil moisture. The water requirements of deficit irrigation were found to be 35% lower than that of normal irrigation (control), and both transpiration and the interplant evaporation reduced. The water requirement of winter wheat was similarly reduced by 39%. Rice production increased by 9.5% under deficit irrigation but winter wheat was less than 4%. Water production efficiencies increased by 70% for both rice and winter wheat.
