MANAGEMENT OF MODIFIED SURFACE IRRIGATION SYSTEM FOR SOME FIELD CROPS USING AN EXPERT SYSTEM

Abstract

The study aimed to build and evaluate an expert system for managing a modified surface irrigation system for some field crops. The expert system can perform two different tasks. The first task is to make irrigation scheduling for some field crops. The second task is to provide the user with information about operating the gated pipes as one of surface irrigation modification tool. To achieve this aim carried out the following: 1- The compilation and composition of expert system program called MSIS-ES for managing a modified surface irrigation system using gated pipelines by the language of C#.net. The proposed program has been explained and its content reference data (site information- soil characteristics- climatic data- irrigation options). As well as all the used equations and rules used in estimation of the variables of irrigation management. 2- The program’s database was designed for lengths of crop development stages for various planting periods and climatic regions, single crop coefficient (Kc) for non-stressed well managed crops in sub-humid climates, ranges of maximum effective rooting depth and soil water depletion fraction for no stress for some crops
