| Abstract | ||
| This study was conducted in the fields of Agriculture and Forestry collage in March 2005 to investigate the effect of a sprinkler spray nozzle heights (30 and 90 cm), spray nozzle diameter (3.1 4, 3.1 5 and 3.1 6 mm) soil surface level (sloped 20 %) and leveled and the interaction effect of the three previous factors on the water distribution uniformity. The randomized block design and Duncan's multiple range test for comparison between the means were used. Results showed that there was no significant differences between the water distribution uniformity of the soil surface levels. However, the spray nozzle height of 90 cm gave the highest water distribution (58.05%) and it was significantly differ from other height (30cm) the spray nozzle diameter of 3.1 6 mm gave the highest water distribution (58.627%) compared with other diameter. The interaction between spray nozzle height of 90 cm and diameter of 3.1 6 mm with level soil surface gave the best water distribution of 72.51% while the same spray nozzle height and diameter and sloped surface (20%) the second best water distribution (69.14%). | ||
