Abstract: Currently, the economic wheat production faces severe challenges due to an increasing number of droughts. In an effort to enhance yields, most arid and semi-arid areas increase the water volume used for irrigation and cultivation of wheat, resulting in an intensified pressure on water resource systems. Therefore, it has become increasingly important to determine the required water volume per unit area in relation to expected wheat performance. However, such an estimation of relevant performance factors has been difficult due to unpredictable water supply capacities and the lack of reliable estimates for the demand of water. The potential crop water productivity (PCWP) defined in this study was comparing with its actual value has which obtained from field measurements based on a new approach of risk quantification. Using this comparison of water use, the management coefficient was estimated, and the production reliability of wheat was calculated.
