This paper discussed the implementation of Sine-Product model for estimating the real crop water requirement of a particular region. The optimal crop water requirement is supposed to be varied spatially. The crop being investigated is corn in four different regions. The indicator of fit is the average of absolute differences between the values of yield produced by the Sine-Product model and recorded data of yield. The results indicate that the optimal crop water requirement is differ somewhat from the established one.
