Abstract

The aim of this investigation is to evaluate the consumed energy under surface and subsurface drip irrigation techniques in hyper arid condition of Siwa Oasis with using low quality water. Experimental treatments were done at Siwa Oasis – Matruh Governorate. The experimental results showed that energy applied efficiency (EAE, 1.75 kg/MJ), and without escalation (with escalation) benefit/cost ratio 6.16 (5.60) were obtained from with underneath PE sheet, at 10 cm dripline depth, 0.9 – 1.2 m dripline spacing, and VSL (two Vertically Spaced Line) arrangement.
