تأثير إضافة محسنات التربة في ثباتية التجمعات باستخدام طريقتي الري بالتنقيط و الري السيحي في التربة الطينية و نمو نبات الذرة الصفراء (Zeamays L.)‎

Abstract EN

An experiment was conducted in the field of the college of Agriculture of Basrah University at Garmat Ali site during spring 2011-2012 .

in clay soil texture, to study the effect of adding soil conditioners, which include bitumen emulsion (0.5%) and organic residuals (2%) on the physical properties of the soil and the efficiency of both irrigation systems, drip and Surface irrigation Which included %100EP ، %75 EPand %50 EP.

Maize (Zea mays L.) Class 106 Behoth was used as an indicator of the growth.

The results showed that the addition of conditioners lead to improvement in the mean weight diameter was going up significantly.

The level irrigation the %75 EP showed improvement in some physical properties of the soil, as it lead to significant increase in values of the mean weight diameter compared with levels 50% EP and 100% EP.

Results also showed that the use of drip irrigation maintained the soil structure as a result of significant increase in values of the mean weight diameter compared with surface irrigation.
