The method of irrigation sprinklers topical small (misty sprinkler) of modern irrigation methods that are recommended to follow them Cree complementary in specific cases. To assess the performance of the sprinkler system in terms of the Misty distribution of water to the irrigated area must adopt standards regulate irregular irrigation. I've been in this research study of sprinklers operating pressure of 1 bar to 5 bar and found that the appropriate operating pressure 3.5 bar And has been studied the distribution of water for watering Single (mm height of the water column) without the wind, but in terms of knowledge of the impact of rising holder Sprinkler were selected for the three heights holder Sprinkler (0,4 m and 0.5 and 0.6), and the order of sprinklers has been selected three arrangements sprinklers for women with square shape and rectangle and triangle,And three of the wind speed (3-1-0 m / s) was used two types of topical sprinklers available in the local market, in each of the coefficient (Cu) and (Du).The results showed the superiority Sprinkler Type II (larger diameter nozzle) on the Sprinkler type I (smaller diameter nozzle), and the superiority of the order form for a square arrangement of the rectangle and triangle arrangement Finally, it gave the highest ranking square shape values for Cu% 94,53% and 91.76 Du to the Sprinkler nozzle is larger while he gave for Cu 82,05% and Du 79,84% of the Sprinkler nozzle is smaller.It turned out that he increase the height of Sprinkler holder (0.4, 0.5, 0.6 m) decreased values of each of (Cu) and (Du) the existence of high winds as it gave the Sprinkler stand 0.4 meters higher values for Cu% 93,07 and 89,00% Du to the Sprinkler nozzle is larger while he gave for Cu 80,18% and Du 77,7% of the Sprinkler nozzle is smaller, but without the presence of the winds increased the values of each of (Cu) and (Du) as given the height of Sprinkler holder 0,6 mhigher values for Cu 96,42% and Du 95,11% a Sprinkler with a nozzle while the largest given for Cu 86,23% and Du 83,41% of the Sprinkler nozzle is smaller.And found that an increase of wind speed (3-1-0 m / sec) values of Cu decreased from 95.95% to 91.89% and the values of Du from 94.47% to 87.40% for the Sprinkler with a nozzle while the larger values of Cu decreased from 84.54% to 78.17% and the values of Du from 82.29% to 75.03% for the Sprinkler nozzle is smaller
