Abstract EN
A field experiment was conducted at Selate scheme at Khartoum north, to evaluate the performance of three center pivot sprinkler irrigation systems.
Speeds of these systems were calibrated with depths of water.
Irrigation uniformity and discharges for some nozzles through directly collecting outlet waters were evaluated as well.
Results show differences between values of distribution coefficient, uniformity coefficient and application efficiency in spite of the similarity center pivot system used in this study.
The distribution coefficient management19%, 35% for the system 2, and 3 respectively compared to system 1.
While the uniformity coefficient gave a variation on 5%, 15% for the system 2, and 3 respectively compared to system 1.
The application efficiency was increased by 26% ,51% for the system 2, and 3 respectively compared to system 1.
Difference in depth of water applied was observed as linked with water distribution uniformity coefficient.
In addition, differences in discharges for pivot irrigation systems were observed in spite of constantly operating pressure (30 psi) and percentage of systems speed (60%).
Besides, the delay in making continuous maintenance resulted in clogging some nozzles which affected uniformity coefficient, depths of water collected and nozzles discharges and affected negatively on distribution uniformity of such systems.
