Abstract
A method for estimating crop coefficients using tensiometer and neutron probe data was used. Data for a wheat field site were analyzed using this method to calculate wheat crop coefficients. Crop coefficients were developed for the Class A Pan, Radiation, Jensen-Haise. and Penman methods. The estimated crop coefficients were compared to those of Doorenbos and Pruitt (1977). The crop coefficient polynomial equations produced in this study are useful in estimating crop water requirements in AI-Qassim region.
