دور متطلبات الغسل و عمق الحراثة في خفض تأثير ملوحة ماء الري و تحسين بعض خصائص التربة في نمو نبات الحنطة Triticum Aestivum L. I- بعض الخصائص الفيزيائية للتربة و الحاصل الكلي للحبوب

Abstract EN

Field experiment was conduction in agriculture college researches station/ Basrah university on silty clay soil for planting of wheat crop(Triticum aestivum L.

).

The experiment was included, effect of 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 bulk density, total porosity and soil moisture to both depth of sample collection(0-15) and(15-30)cm.

also total grain product.

Result showed, irrigation water salinity 2 dS m-1 caused stitical decrease for bulk density comparision with treatments 4 and 8 dS m-1, 0, 10% leaching requirement comparision with another ratio and tillage depth (0-50)cm.

comparision with (0-25)cm.

However, moisture content of the soil, the salinity of irrigation water 8 dS m-1 gave the highest values compared to other salinity levels and 30 % leaching requirement compared to other ratios, and the tillage depth was 0-50 cm.

the total porosity of the soil and the leaching requirement 0% compared to the other ratios, and the tillage depth 0-50 cm compared to the 0-25 cm.

while the salinity of irrigation water 2 dS m-1, the leaching requirement 20% and tillage depth 0-50cm were statical increased in the total grain product.
