In recent decades, various sprinkler irrigation methods and installations have been developed to meet the needs of farmers, particularly smallholders. Hand-move sprinkler irrigation is the most widely adopted and least expensive system operated with pressure ranges from 2.0'3.5 bars. The sprinklers are mounted on lateral pipelines temporarily laid across a field. To reduce labor requirements, this system was modified to hose-move sprinkler irrigation. In this modified system, lateral pipelines are placed permanently, and the sprinklers, mounted on tripod stands, are not fitted directly to the lateral pipelines but are connected to them via flexible hoses. The hoses and sprinklers can be moved laterally on either side to cover a number of lateral positions.
