Abstract
This study was conducted in the fields of Agriculture and forestry collage at the June of 9002 to find the effect of three factors, which are two types of spray head (Spanish, Italian), pressure at two levels (5.1,
3) bar and wind speed at two levels, low (3-7) km/h and moderate (50-51) km/h and its interactions on the uniformity coefficient and the distribution uniformity of water. It was using the design RCBD by Spilt - spilt plot system, the spray heads were in the main plots and pressure was in the secondary plots and sub plots take wind speed. The comparison of means values were tested by using the Duncan multiple range test and the results are show the significant differences for each three factors, where the best significant value
72.21٪ at the triangular overlapping of uniformity coefficient with Spanish spray head and the pressure 3
bar with the low speed wind. While the best significant value for the distribution uniformity of water was 75.053٪ when use Italian spray head and 3 bar pressure with the low speed wind.
