Estimating Function of Supply for Barley Crop in Iraq for the Period (1990-2014).

Abstract

Supply is important because it links the quantities of goods produced with the corresponding prices the purpose of the research to estimate the function of barley supply in Iraq for the period 1990-2014. The function was estimated using the Evewis program. The production of barley was a variable and independent variables included mechanization , the amount of fertilizer, the cultivated area, the water, the price of the crop by the use of the OLS method. The linear formula is the most suitable function to pass the statistical and standard tests, and the barley width is increased by 0.79 as the mechanization increased by one unit, while the amount of barley increased by 0.14 as fertilizers increased by one unit. The research concluded that the supply of barley depends on the determinants of the most important prices, but there are other factors that help increase the supply of the crop, including the development of livestock.
