AbstractQuality of Euphrates water is one of the main factore which is important as well as quantity factore in distribution between countries of euphrates zone .In order to study this factor it choice six stations a long of Euphrates river (Der al zour in syria, al qaeem, haditha, ramadi, al semawh and al nasiryh in Iraq). Electrical conductivity, leaching requirement, consumptive use and the quantity of addition salts were calculated.
The results showed that the euphrates water salinity, leaching requirement and the irrigation requirement were increase from Der al zour in Syria to al nasiryh in Iraq at all levels of relative yield of Wheat crop, there for the quantity of salts which addition to the soil was also increase (19) itration with the same direction and the relative value of water unit was decrease with the direction of al nasiryh station in Iraq.
