Abstract
The irrigation and production costs 0 f irrigated citrus farms by four different irrigation systems (drip, low head bubbler, gated pipes and traditional surface irrigation) were evaluated. The results indicated that the capital and total annual costs of traditional surface irrigation (280 and 142.1LEIFed respectively)are considerably cheaper than that of the other irrigation systems, while drip irrigation has the highest capital and total annual costs (2230 and 533.4 LEIFed) for citrus. Irrigation water requirements for citrus irrigating were reduced by 44.4%, 37.5% and 23.1% when using drip, bubbler and gated pipes irrigation systems respectively compared to the traditional surface irrigation. On the other hand, the citrus yield reduced by 13.8%, 8.2% and 3.7% under drip, bubbler and gated pipes irrigation systems respectively compared to traditional surface irrigation in the first season, while, the yield increased by 37%, 20.5% and 6.8% under drip, bubbler and gated pipes irrigation systems respectively in the third season. This increase in yield under drip and low head bubbler irrigation systems helped in covering the initial cost of these systems. The highest net profit (2746.6 LEIFed) for citrus was obtained by using drip system, followed by low head bubbler (2375.6 LEIFed), while the lowest net profit was (1902.9LE/(ed) by using traditional surface irrigation.
