Abstract
The aim of this investigation is to evaluate the behavior of salt concentration distribution under surface and subsurface drip irrigation technique in Siwa Oasis hyper arid condition with using low quality water. The experimental results showed that salt moving from surface to the root zone in Adjacent Lines (AL) was more than Vertically Spaced Lines (VSL) and increasing dripline depth decreased the accumulated salt. In case of without Poly-ethylene (PE) foil, the best WUE for onion reached 0.5 kg/m3 in the case of VSL with 0.8 – 1.0 m spacing and 10 cm depth and the highest onion (2.42 t/fed) yield under VSL arrangement was obtained from 10 cm dripline depth and dripline spacing range 0.4 – 0.6 m. In case with PE foil, the highest onion yield under VSL arrangement (2.9 t/fed) was obtained from 25 cm dripline depth and dripline spacing range 0.3 – 0.6 m.
