A field experiment was conducted in the n agriculture college researches station /Basrah University on silty clay soil for the planting of wheat crop (Triticum aestivum L.). The experiment was included the effect of different irrigation water salinity levels (2,4 and 8) ds m-1, leaching requirement (0, 10, 20, and 30) % and tillage depth (0-25) and (0-50) cm.  and their interaction on electric conductivity (ECe) for both depth of sample collection (0-15) and (15-30) cm. also dry shoot matter weight, leave the content of nitrogen, phosphor, potassium and total grain production. The result showed statistical superiority of irrigation water salinity of 2 ds m-1 over other treatments of 4 and 8 ds m-1, 30% leaching requirement over the other portion, in addition, the tillage depth (0-50) cm. over (0-25) cm. Regarding dry matter leaving the content of nitrogen, phosphor, potassium, and total grain product, the result showed the same behavior as irrigation water salinity and tillage depth effect on soil salinity. While nitrogen and phosphor leave content with a 10% leaching requirement was statistically superior over the other, however, a 20% leaching requirement caused a statistical increase in dry matter weight, potassium leave content, and total grain product.
