Irrigation Management Effects on Yield and Water Productivity of Inbred and Aerobic Rice Varieties in Kaifeng

Abstract

"This study aimed to test the hypotheses that aerobic rice with high water productivity can be grown successfully in Kaifeng and that the effects of irrigation regimes on water inputs, grain yield, and water productivity vary with different groundwater depths. Experiments in this study were to quantify the effects of different irrigation water management regimes, ranging from rainfed to continuous flooding, on growth, yield, and water productivity of conventional and aerobic rice varieties at two sites with contrasting groundwater depths in Huibei, Kaifeng, China."
