Abstract. Variable rate irrigation (VRI) sprinklers on mechanical move irrigation systems (center pivot or lateral move) have been commercially available since 2004. Although the number of VRI, zone or individual sprinkler, systems adopted to date is lower than expected there is a continued interest to harness this technology, especially when climate variability, regulatory nutrient management, water conservation policies, and declining water for agriculture compound the challenges involved for irrigated crop production. This article reviews the potential advantages and potential disadvantages

The specific focus of this work is conserving irrigation water in Iraq. Agriculture is the main sector that consumes fresh water globally, mostly for irrigation, and it will be the sector most affected by increasing water scarcity. Nowadays, the low-pressure sprinkler has been widely used to replace highpressure impact sprinklers in linear-move sprinkler irrigation systems due to its low operating cost and high efficiency. However, the hazard of increased surface runoff represents the biggest obstacle for low-pressure sprinkler systems. Variable-rate irrigation (VRI) techniques have been used
