The Effect of Irrigation with Sulfuric Saline Water on Some Majer Soil Properties and Productivity of Maize Crop

دراسة تأثير الري بالمياه المالحة الكبريتية في بعض خصائص التربة الأساسية وإنتاج الذرة الصفراء وذلك باستخدام طريقة الري بالخطوط لأربع معاملات : معاملة شاهد تمَّ ريُّها بمياه عذبة, معاملة (1) تمَّ ريُّها بمياه مالحة كبريتية وفق مقنن ري الذرة الصفراء, ومعاملة (2) رُويَت بمياه مالحة كبريتية وفق المقنن المائي + نسبة غسيل 20%, ومعاملة (3) تمَّ ريُّها بمياه مالحة كبريتية وفق المقنَّن المائي+ نسبة غسيل 30%,وأظهرت النتائج تفوق المعاملة 3 (نسبة غسيل 30%) على معاملة الشاهد والمعاملة1 (من دون غسيل) والمعاملة 2 (نسبة غسيل 20% ) من حيث التأثير في نسبة الإنبات والإنتاجية(غلة العرانيس الطازجة مع الأغلفة طن /ه) , في حين حققت المعاملة (2) المروية من دون استخدام معدل غسيل أدنى نسبة إنبات وإنتاجية إذ كانت القراءات كما يلي : نسبة إنبات الشاهد 95% و المعاملة (1) 90% و المعاملة (2) 95% و المعاملة (3) 97% أما إنتاجية الشاهد فكانت 32.4 طن /ه و المعاملة (1) 30.25 طن /ه و المعاملة (2) 33.6 طن /ه و المعاملة (3) 39.037 طن /ه . وهذا يدلّ على أن الري بمياه مالحة كبريتية وفق (المقنن المائي للذرة الصفراء + غسيل 30%) حقق أفضل النتائج من خلال الحصول على إنتاج جيد وتوفير المياه العذبة والمحافظة على الخصائص الأساسية للتربة.

The research was conducted in order to study the effect of irrigation with sulfuric saline water on some major soil properties and maize production The flood irrigation process was carried out with four treatments: Treatment of witness was irrigated with fresh water, treatment No. (1) was irrigated with sulfuric saline water according to the standardized maize irrigation, and treatment No. (2) was also irrigated with salty sulfur water standardized for maize irrigation + 20% washing rate, and treatment No. (3) was irrigated with water Sulfur saline according to maize irrigation standard + 30% washing rate,The results of the study showed that there was a slight significant difference between the four treatments in terms of the apparent and real density, while there were clear significant differences between the treatments in terms of ESP%, EC and carbonates with depth, and this was the result of washing salts with the excess amount of irrigation water used for washing. The results also show that treatment No. (3) was the best of germination percentage and productivity, while treatment No. (1) achieved the lowest germination and productivity(Fresh maize cobs yield with wrappers) , as the readings were as follows: The percentage of germination in the witness was 95%, in treatment (1) 90%, and in treatment (2) 95% and in treatment (3) 97%, while the productivity was in the witness 32.4 tons / ha and in treatment (1) 30.25 tons / ha and in treatment (2) 33.6 tons / ha and in treatment (3) 39.037 tons / ha. This indicates that irrigation with sulfuric saline water according to (water ration for maize + 30% washing) achieved the best results, as the economic feasibility of using sulfuric saline water was achieved by obtaining good production, providing fresh water and preserving the major properties of the soil.
