In today's world we are all more aware of the need to conserve fresh water. Competion for fresh water among different water-use sectors in several arid and semi-arid regions is expected to increase and consequently it allocation to irrigation is expected to decreas. It makes sense to try to use non-conventoinal water resources, such as saline drainage water for crop production. A 3-year irrigation experment was conducted in Al-Hassa region of Saudi Arabia to evaluate different irrigation strateges for using saline drainage water to irrigate date palm (Phoenix dactylitera L.)on loamy sand soil (EC=2.9-3.6dS/m,pH=7.5-7.7,SAR adj=6.3-7.4,infiltration rate=0.623-0.920cm/hr).The treatments were:1.Irrigation with well water (WW). 2.Irrigation with drainage saline water(DW)(EC=11.2 dS/m,pH=7.5,SAR adj=31.6),3.Cyclic use of well and drainge water through alternate irrigaions (WW-DW). at the end of experiment,it was observed that there was an increase of soil EC up to the depth of 150 cm as irrigation water salinity increased with ions of highly soluble salt (especially NaCl)contributed to soil EC.Drainage water leads to considerable increase in soil salinity even over a short period of growth. The percentage of exchangeable sodium (ESP) increased with the use of drainge water.Both EC and ESP gradually decreased with depth.Drainge water adversely affected soil physical traits (Bulk density and infiltraion rate) by affecting the aggregate stability index in water.
