A computer program was developed for determination of crop water requirements using local meteorological and research data, and also using Visual Basic 6.0 Programming language. For verification of the model, field trials were carried out during the period December 2007 – July 2008 at four schemes using center-pivot irrigations in the northern parts of Sudan. The program was based on using Penman equation and Penman-Monteith method. Results were comparable to those obtained through traditional time-consuming methods. The program could offer a simple tool for planning crop water requirements for agricultural projects.
Keywords: computer program, crop water requirement, modified penman equation, penman monteith method.
