ESTIMATION OF THE TECHNICAL EFFICIENCY OF WHEAT FARMS UNDER THE SUPPLEMENTARY IRRIGATION SYSTEM USING THE STOCHASTIC FRONTIER APPROACH (NINEVEH GOVERNORATE- ALBAAJ DISTRICT AS A MODEL)

Abstract

Wheat production in Iraq under permanent farming systems faced sharp seasonal fluctuations during the previous years resulting from Climate fluctuations that affected the output , and for the rational use of scarce water resources, an effective system to improve irrigation, and the research aimed To estimate the technical efficiency of wheat farms by means of random correlation analysis using the logarithmic production function, based on field data for a random sample of 30 farms in the district of Al-Baaj Nineveh Governorate for the agricultural season 2020-2021. The results of estimating the technical efficiency showed that the research sample achieved a technical efficiency of 94%, which means that a waste of resources was 6%, so it is the responsibility of this sample to produce the same amount of wheat using only 94% or less of the inputs to reach the optimum efficiency. Also, there is a positive relationship between the number of irrigations, the amount of pesticides, the area, and the yield of wheat, while this output is associated with an inverse relationship with agricultural work, the amount of seeds and fertilizers, as an increase in the amount of fertilizers, the quantity of seeds, and agricultural work by 1% leads to a decrease in wheat production by 0.261% and 0 723% and 0.159%, respectively. This may be attributed to the use of these resources at a rate that exceeds the plant’s need for these resources, and this in turn led to waste in resources and thus a decrease in technical efficiency below the optimal level.
