AbstractA field experiment was achieved at Al-Saqlawia Discreet / Al-anbar Province to study the effect of operation pressure and emitters' discharge on each of discharge variations, uniformity coefficient, and emission uniformity.
Turbo type of emitters was chosen with two designed discharges , namely; 4 and 8 L.hr ˉ ¹. While the irrigation system was operated with three operation pressures , namely; 30, 40 and 50 Kpa. Actual discharge of emitters was measured, which discharge rates, discharge variation, uniformity coefficient and emission uniformity were calculated.
The results showed that 50 Kpa operation pressure gave a nearest values for design discharge of emitters reached to 3.94 and 7.88L.hr ˉ ¹. Also, uniformity coefficient, emission uniformity and discharge variation values were the best values 96.77, 95.69, 9.64% and 96.21, 95.81, 9.58% which used, respectively.
