Some ecological impacts of eastern Euphrates drainage water on basil (Ocimum basilicum)

Abstract

Abstract Iraq is one of counters that effected with climate change which meagre its effects is reduce water resource. Study the ability of using eastern Euphrates drainage water as a alternative water resource in the irrigation. Basil was used as an example to sensitive plants. it given a good growth under using drainage water by several biochemical adaptations including increased each of MDA, TAA, proline, GSH and ROS levels. The drainage water was not polluted with Zn, Cd, Fe, Cu and Pb which their concentrations were 0.001, 0.1837, 0.001, 0.1112 and, 0.0035 ppm respectively, and these concentrations are within Iraqi limits of irrigation, but with elevated concentrations of total hardness about 880 Mg/L. The current study explained that eastern Euphrates drainage water is not saline and can used in the irrigation of crops and it was not polluted with heavy metals.
