Abstract: An Irrigation Management Information System (IMIS) was developed for complex irrigation projects involving a large number of farms under severely arid conditions. This system is a computer program implemented on an IBM Personal System/2. The system consists of a main program and fourteen subroutines developed using Fortran 77 language. The IMIS is capable of predicting the reference crop evapotranspiration, crop water requirements, irrigation scheduling and water demands for different type of plants under water shortage conditions. The crop yield response to water and the contribution of the shallow groundwater for different types of crops were also considered in this system Additional aspects of the subject are discussed.
