Three Operating Pressure Levels for fixed irrigation system included: 1, 1.5 and 2 bar. The following characters were studied, which are the amount of water used during the season, sprinkler service area, plant height and maize yield. A randomized complete block design (RCBD) was used with three replications, and the least significant difference under probability (LSD= <sub>0.05</sub>) was used to compare the averages of the transactions. The results showed the following: The superiority of the operational pressure of 1 bar in the amount of water used during the season (81 m<sup>3</sup>. Season<sup>-1</sup>), superiority of the operating pressure of 2 bar in obtaining the the highest value of the sprinkler service area was 367.71 m<sup>2</sup>, the highest plant height was 190.11 cm, and the highest yield of the crop was 6.46 tons. ha<sup>-1</sup> comparing with other treatments.</p><p><strong> </strong></p> ER -
