ESTIMATION OF THE TECHNICAL EFFICIENCY OF WHEAT FARMS UNDER THE SUPPLEMENTARY IRRIGATION SYSTEM USING THE PROGRAM STOCHASTIC FRONTIER APPROACH (NINEVEH GOVERNORATE - AL-BAAJ DISTRICT AS A MODEL)
Mesopotamia Journal of Agriculture,
Wheat production in Iraq under permanent farming systems faced sharp seasonal fluctuations during the previous years resulting from the fluctuation of climatic conditions that affected yield and production, 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 analytical method The random borderline and using the superior logarithmic production function, based on field data for a random sample of 30 farms in the district of Al-Baaj, Nineveh Governorate. 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, and it was also found that there is a positive relationship between the number of irrigations, the quantity of pesticides, the area and the yield of wheat, while this output is related to an inverse relationship with agricultural work and the quantity of seeds And fertilizers, whereby an increase in the amount of fertilizers by 15% exceeds the need for the crop of wheat by 1%, which leads to a decrease in production by 0.15%, and this in turn led to Waste of resources and consequently low technical efficiency below the optimum level.
