A Comparative Study of Standard Center Pivot and Growers-Based Modified Center Pivot for Evaluating Uniformity Coefficient and Water Distribution

The center pivot irrigation system is a type of technology used to apply water effectively and uniformly over wide variety areas topographies. These systems’ uniformity application greatly affects use, energy consumption, crop production. Performance tests the standard lateral galvanized modified polyethylene plastic pipes in systems were conducted different regions Saudi Arabia. Water distribution depths along laterals, coefficient (CU), low quarter (DU) determined. results revealed that profiles ranged from 4 14 mm for standard-center systems, while those modified-center 6.5 50 mm. Standard-center CU values 74 90%, with an average 86%. In comparison, 62 83%, 78%. DU 60 82% overall 77%. For values, contrast, 31 75%, 65%. Thus, accuracy are superior have been modified. Additionally, statistical model was developed investigate relationship between losses main climatic factors under field operating conditions. Therefore, study expected draw attention pipes’ value on one hand demonstrate detrimental consequences growers’ incorrect practices motivating them take strong action against these activities, other hand.
