An experiment to compare the performance of different solid-
set sprinkler patterns was carried out during March and April 2004 in the
Demonstration Farm of the Faculty of Agriculture, University of
Khartoum at Shambat. The experiment consisted of testing the effect of
square, rectangular and triangular sprinkler patterns on Christiansen's
coefficient of uniformity (CU%), uniformity of distribution (DU%) and
water loss (%) using the completely randomized design. The triangular
pattern recorded the highest uniformity coefficient and uniformity of
distribution and the lowest water loss. Water distribution uniformity
(CU% and DU%) and water loss (%) were not significantly affected by
sprinkler patterns. However, mean CU% and DU% had the following
decending order: triangular pattern > square pattern > rectangular pattern,
while mean values of water loss (%) was as follows: rectangular pattern
> square pattern > triangular pattern.
