Abstract. By using the corn demonstrations from a local research, the production functions for corn with respect to total available water (TW), irrigation application and Percentage of Potential Evapotranspiration (PPET) are established to represent the conditions in the Texas Panhandle area. The production functions and the total cost function generated are used to determine the optimal level of water application and the corresponding maximized profit. Also the benefits of ET information is analyzed and proved to be valuable in the decision-making process aimed at improving water-use efficiency.

Key words: corn, irrigation efficiency, yield-water response function, ET
