CENTER PIVOT IRRIGATION ATTACHED SPRAYER

Sprayers were designed and installed on a four-tower and a single-tower center pivot irrigation system. The center pivot-attached sprayer systems use micro-irrigation equipment to reduce investment costs and provide ease of installation. Water application uniformity was determined with a computer simulation model and an aircraft spray pattern sampling analysis system. Micro-irrigation sprinklers spaced 3 to 3.6 m (10 to 12 ft) apart on a separate pivot mounted sprayer manifold with drop tubes 2 m (6 ft) above the ground resulted in 87 to 95 coefficient of uniformity.
