Evaluation of Center Pivot Sprinkler irrigation System (Lindsay type)

Abstract

The experiment was conducted in Al-anbar governorate-Al-saqlawla during (Autuman season 2002), to evaluate Center pivot sprinkler irrigation system (Lindsay type).The system speed was calibrated with water depth achieved from that speed. The relationship between speed percentage for system, and the irrigation uniformity, also the operation pressure and irrigation uniformity has been studied. The operation of the system under pressure nearly 30 psi gave high irrigation uniformity cofficient reached 89%.
