Evaluation of central pivot irrigation system under different soil and climatic conditions

Abstract

The centre pivot irrigation system is increasingly becoming popular among farmers around the world on account of the benefits the system can offer compared to other methods. Due to the low irrigation efficiencies and high water losses of surface irrigation and rise of water management and operation costs, the general trend in most of the country is to adopt modern pressurized irrigation systems. Subsequently, large numbers of center pivot systems have been introduced. The efficiency of a center pivot is solely dependent upon the operating parameters and the hydraulic design of the system. Uniformity coefficient from center pivot irrigation should exceed 90%. Recent developments in the center pivot industry have led to contractual relationships between after-market suppliers and irrigation system manufacturers that should support further development of site-specific application of water, nutrients and pesticides in the future. This review article highlights installation and evaluation of Central Pivot irrigation system in different type of soil and climatic conditions and gives an insight of their valuable application in increase in water user efficiency.
