Abstract

In this study the samples of southern drainage water and Euphrates river water were taken from the north region of Al- Manadhra city [Najaf province-Iraq].Those samples were mixed with different ratios by adding drainage water to river water to get a new solution containing different salt. To find a standard indicator of water quality that sodium adsorption ratio (SAR) as well as examine electrical conductivity (E.C.).The results were (3.15, 3.9, 4.2, 4.8, 5, 5.2, 5.3, 5.4, 5.5, 5.6, 5.8) for (SAR), (1.58, 2.3, 3.06, 3.75, 4.35, 5.11, 5.85, 6.33, 7.2, 7.63, 8.2) for (E.C.) respectively.
Then, examine those samples of salt water where used as an irrigation water supplied to several types from of Oryza satival seeds (Al-forat class, Yassmin class, Amber Baraka class) to test germination of seeds. The results of germination of seeds with those samples of irrigation water at mixing drainage water ratios (0-100)% equal to (100-5)% for Al-forat class, (90-0)% for Yassmin and Amber Baraka class respectively
