Irrigation Scheduling Effect on Water Requirements

Irrigation scheduling techniques is one of the suggested solutions for water scarcity problem. The study aims to show possibility using practical and applicable irrigation program which was designed by Water Resources Department at University Baghdad Spreadsheet Formulas Microsoft Excel program, version 2007, with some modification generalize it made various climatic zone different soil types, as a salvation shortage inside projects. projects incidence Tigris River basin will be taken an example. This based on budgeting programmed depending scientific concepts facilitate structures operation ease use farmers. By abilities this monthly annually requirements drainage were estimated. Finally comparison between calculated discharges designers ones. comparisons showed that type (i.e. predicted scheduling) itsapplicable constrains require high attention when choosing cropping pattern each climate zone. Also found useful tool saving if has been chosen carefully.
