دراسة اقتصادية لأثر اختلاف مصدر الري على إنتاجية محصول القمح بمحافظة الغربية

الملخص EN

The Wheat crop is considered one of the most important crops in Egypt as it is a food and industrial crop that underpins many food industries.

This study aimed to studying the economic efficiency of using the available water resources in Wheat producing and trying to reach the maximum possible return with available resources in the presence of a clear waste in the use of irrigation water in Egypt in general and in the middle of the delta in particular as a result of adopting the method of flooding irrigation.

which leads to a high level Ground water.

blockage of drains.

and loss of fertilizer residual crops with wastewater.

leading to deterioration of acre productivity.

as well as a decrease in per capita food share.

By studying the current situation of water resources and the efficiency of irrigation water management according to the different irrigation sources in Gharbia Governorate.

The results showed that Al-Gharbia governorate’s share of fresh water decreased from about 2.09 billion cubic meters in 2010 to about 1.08 billion cubic meters in 2018.

with a decrease of about 48.33%.

which is a substantial percentage.

The total return to the total costs in the wheat crop irrigated using canal water at the Mahalla al-Kubra center reached its highest value compared to other irrigation sources.

reaching 1.65.

And the return of the pound invested in the production of wheat acre.

which was irrigated using canal water.

reached the highest value of about 0.65 pounds.

The return of the pound invested in the production of wheat acre.

which was irrigated using canal water.

reached the highest value of about 0.71 pounds.

By studying the Production function between the amount of the output of wheat crop irrigated with canal water as a dependent variable.

and some productive factors as interpreted variables show that the most important factors with a positive effect on the amount of wheat output are the factor in the number of human work hours.

and the amount of seed used.

while the effect was The water component is negative.

which indicates a great extravagance in this resource.

By studying the Production function between the amount of the output of wheat crop irrigated with groundwater as a dependent variable.

It show that the most important factors with a positive effect on the amount of wheat output are the element of the number of human work hours.

and the amount of seeds used.

while the effect was The element of water is negative.

which indicates that there is a water waste.

By studying the Production function between the quantity of the output of the wheat crop that was irrigated with the mixture water.

as it was found that the most important factors that have a positive effect are the number of hours of the human element.

and the amount of phosphate fertilizer.

while the effect of the water element was negative.

which indicates that there is a water waste.

By studying the most important reasons for farmers resorting to using irrigation with ground water and mixed water.

it became clear that draining of canals and water shortages in the governorates was indicated by about 19.48% of the respondents in the sample.

From above results.

the following recommendations could be stated: 1- Working to change irrigation systems from flood irrigation to sprinkler irrigation in field crops.

2- Awareness of the need to rationalize irrigation water consumption.

3- Developing new varieties of crops that consume less water 4- Recycling and using the wastewater in agricultural.
