In: Misr Journal of Agricultural Engineering 2002.v.19(2)Summary: This investigation dealt with small center-pivot sprinkler "CPS" (90m boom, 50-100 m3/h, and 9.7 fed coverage) in new lands. The "coefficient of uniformity" and "distribution uniformity" were 83 and 72 % respectively for the low-discharge CPS (50 m3/h), which are less (by 13-18 %) than reported in other literature. Values were even less with the high-discharge CPS (100 m3/h). More attention should be paid, in future work, to lower-discharge CPS systems with improved uniformity. Kev Words : Center-pivot sprinkler sprinkling, sprinkler irrigation, sprinkler system emission uniformity (EU), Coefficient uniformity (CU).
