This experimental work was conducted during 2007 to study and to evaluate sprinkler irrigation system in order to improve efficiencies and management of system on cotton crop. The experimental work and data collecting on irrigation practice and operational condition were carried out in Gemmeza research station Gharbia Governote. The results reveal that by using Bondok computer program in evaluating sprinkler system. Increasing both average low quarter 21.5%, Individual Sprinkler Discharge 11.11% Distribution Uniformity (DU) % ; Coefficient of Uniformity (CU) %; Potential Application Efficiency of Low Quarter (PELQ) % and Application Efficiency (AE) % by 22.1; 9.1; 8.9; 9.5 respectively. Nevertheless decreased value of Efficiency Reduction (ER) % by 21.0 %. Due to use of sprinkler irrigation system, the yield decreased by 10.2 %. Nevertheless , due to sprinkler irrigation system use the water use efficiency increased by 75%. The data show that by using sprinkler irrigation system the amount of water saved increased by 50.9%.
