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.
