Abstract
The Irrigation sector in different part of world including Iraq is a major water consumer to produce adequate food for increasing high population growth and meeting the MGD food goal. The challenges for the Iraq agriculture sector are to increase food production through effective management of the available and potential water sources including drainage and treated waste water and at the same time conserve and protect its environmental.(Ayers, R. S., and D. W. Westcot. (1985). In Iraq, the water users in different districts and policy makers are showing increasing interest in increasing the reuse drainage water as means of augmenting dwindling useable water supplies. Waterhowever its quality must meet crop tolerance to achieve optimal production and reduce environmental impact. To evaluate feasible option this study is concerned with assessing the suitability of drainage water of Al-Masab Al-Aamlocated for irrigation with or without treatment. Al-Masb Al-Aam drainage passes through the territory of governorate of ThiQar for part of the course covering 180 km out of the565 km and the discharge of the total 220 m3 / . The approach is to evaluate the chemical and physical properties of drainage water from the nearby irrigated field and and the water of Al Gharraf river in the Al-Fajr city northern of Nassiriyah, and the water of the Euphrates River south of Nassiriyah. The drainage water was to be blend fresh water of the nearest river through revaluating different ratios of blending starting with R1 which represents 90% drainage water blended with 10% river water, R2 ( with 80% drainage water and 20% river water andand followed by blending ration up (R3 - R9)to nine trials. Monthly water samples were taken from four locations: two from drainagewater and two from rivers over the period from June 2011, to July 2012.Physically and chemically analyzed for EC,TDS, PH, Ca++, Mg++, Na+ , K+ , Cl- , SO4, NO3 , Turb. , PO4 and T.Hwere carried out on 48 samples. The analyses indicated that the Sodium Adsorption Ratio (SAR) for drainage water was less than 12, which is acceptable for irrigation use. In terms of salinity, the drainage water of Al-Masab Al-Aam its acceptable for irrigation because the halophytes can be irrigated with EC) less than 8000 Micro Siemens/cm. The blending between the drainage water and the fresh water of Al Gharraf river showed showed god blending ratio (R7) having the EC) less than 3000 Micro Siemens/cm.
