Usage of Eastern Euphrates drainage water in irrigation of Olerace (Spinacia oleracea)

Abstract

Climate change effect many countries and Iraq is one of them, which affects water resources. Olerace(
Spinacia oleracea) was grown well when using water of drainage by increasing content of MDA, GSH, ROS
and proline as a biochemical adaptation, their concentrations increased to : 18.08 (mmol/l), 4.59 (µmol/l).,12.05
µg/g and 4.14, respectively.The concentrations of Zn , Fe and Cu in eastern daring water were : 0.001, 0.001
and o.111 Mg/L, respectively Although it was having higher amounts of total hardness, drainage water was
within irrigated water's limitations. The results of current study showed possibility utilize the drainage water
from the eastern Euphrates which is not polluted with studied heavy metals and not saline and it is suitable for
irrigation of plants.
