Performance Characteristics of Micro-sprinkler Irrigating
Greenhouses in Saudi Arabia
Hussein M. Abo-Ghobar and Ahmed I. Al-Amoud
Six types of micro-sprinklers were tested under controlled conditions inside a greenhouse at three operating pressure level; 100, 150, 200 k Pa (1, 1.5, 2 bars). The performance characteristics including uniformity. Water application rate and water distribution patterns were studied. A comparison between the actual measured data and the data reported by the manufacturer showed that there were some variations possibly due to inaccuracy in nozzle designs. The results of this study may assist the agricultural and system designers to select proper irrigation nozzles locally available for efficient water use and some recommendations were suggested.
