دراسة اقتصادية لترشيد استخدام مياه الري الحقلي

الملخص EN

This study examines the rationalization of field irrigation water use through a questionnaire from some farmers who applied developed irrigation systems and comparing the results with regular field irrigation methods in order to generalize the developed field irrigation method in most of the delta lands.

The research was based on cross - sectional data collected from farmers in Kafr El - Sheikh Governorate.

The economic indicators of crops were wheat.

sugar beet.

alfalfa.

cotton.

maize and rice for both traditional irrigation systems and developed irrigation systems in terms of irrigation costs.

total costs.

productivity.

total yield.

and net return.

The results showed an increase in the productivity per feddan of the study crops as a result of the developed irrigation by 11.8%.

22.2%.

10.5%.

15.4%.

12.5%.

6.25% for wheat.

beets.

alfalfa.

cotton.

maize.

rice.

respectively.

and the net return increased for Cotton by three times more than it's in the regular field irrigation.

also the net return for sugar beet and maize crops increased to double compared to that of regular field irrigation.

as the study showed that the developed irrigation systems led to an increase in net return by 85.8%.

21.7%.

17% for wheat.

alfalfa and rice respectively.

In the context of these results.

the study recommends further experiments and researches based on the generalization of developed irrigation methods for the rest of the crops to help decision makers in taking appropriate production policies that will increase the production of agricultural commodities and reduce the imports.
