AbstractDue to the scarcity of water quality degradation in recent years in Iraq in general and specially in Basra province Particular study carried out by selecting two source of irrigation water ,one of them was a branch of Shatt Al-Arab at the site of the University of Basra / Garmat Ali , and the other was wastewater of University of Basra / Garmat Ali . Wastewater was treated in the field using sand filter and used as a third source of irrigation, in addition to tap water as control treatment for field experiment . Irrigation water samples were collected through three seasons. Chemical and physical properties of irrigation water were identified ,and evaluated the suitability of irrigation water for irrigation according to American salinity laboratory 1954, Ayers and Westcot 1985 , American Environmental Protection Agency, and FAO Food and Agriculture Organization . Results of chemical and physical analysis for four irrigation water during the studied seasons showed that the average values of electrical conductivity, pH, Calcium ,Magnesium, Sodium, Sulfate ,Chloride concentration were [1.53-10.53 dsm-1],[7.4-7.9],[130.66-672 mg L-1],[29.16-327.04 mg L-1],[311.8-914.23mgL-1],[275.46-859.41 mg L-1],[521.2-1806 mg L-1] respectively and heavy metals[Cd,Cu,Pb,Zn,B] were[0.052-0.88 mg L-1],[0.026-0.67 mg L-1],[0.03-0.26 mg L-1],[0.021-0. mg L-1 ],[1.17-3.5 mg L-1] and physical properties[TSS and TDS]were [159.33-3235 mg L-1],[981.33-6233.33 mg L-1] and biological properties[COD and BOD]were[1.31-564 mg L-1],[1.02-75.85 mg L-1]. The results of statistical analysis showed the presence of a significant difference between the types of used water for some chemical properties. The irrigation water quality was with very high salinity for for Shatt Al-Arab river American salinity laboratory 1954 and intermediate to high salinity according to Ayers and Westcot 1985 and has effect on planted crops.
