A 28 season field experiment being used to analyze the responses of winter wheat yield and WUE to ET. Yield and WUE being continuously increased from 1987 to 2015 under irrigated condition. Yield was reduced under rainfed condition recently due to the reduction in rainfall. The sensitivity of grain yield to the fluctuation in seasonal ET was increased.
