Effect of Sprinkler Maintenance on the Performance of Center Pivot System

in the Kingdom of saudi Arabia 

Ahmed I. Al-Amoud and Hussein M. Abo-Ghobar

            Field experiments were conducted on six center pivot irrigation systems randomly selected, to evaluate their water distribution uniformity. Tests were made during two successive seasons. The first test was done before maintenance while the second was carried out after a thorough maintenance of all the six systems. Results of the second season (after maintenance ) have demonstrated the effectiveness of maintenance where the coefficient of uniformity (Cu) of all tested systems have improved. In view of the results obtained, some recommendations were suggested in order to increase the performance of center pivot systems.
