Abstract

Research set to optimal values of net irrigation nor m flooded rice, filtration outflow and yields: 1. the net irrigation norm - 19-20 thous. m3/ha; 2. filtration outflow - 7-8 thous. m3/ha; 3. the yield of rice - 50-51cwt/ha. Optimal soil moisture for rice, which requires little water - 0.8 HB, irrigation norm - 10-11 thous. m3/ha, yield - 40-41cwt/ha, the depth of groundwater - 2 m.
