In our evaluation of three microirrigation systems used in greenhouse cut-flower production, the systems' ability to apply water uniformly varied widely. The most common irrigation system, the perimeter system, generally applied water less consistently than other tested systems. Center riser and drip irrigation systems generally applied water more uniformly than the perimeter system. And while many perimeter irrigation systems could be retrofitted to improve water distribution, all irrigation systems could be improved with a regular maintenance program consisting of flushing rust and other particulates from irrigation pipe, and chemically controlling biological growth in irrigation pipe.
