Determining the optimal size of production and measuring the specialized efficiency in grape production farms in Diyala Governorate - Iraq for the season 2021

Abstract

Abstract:In this research, an economic analysis it conducted for a sample of orchards producing grapes in Diyala Governorate - Iraq for the production season 2020-2021. Through a questionnaire conducted with (141) producers, the multivariate production function was estimated. Including quantities of chemical fertilizers, organic fertilizers, the amount of control pesticide, the number of labor hours per dunum, the number of irrigation hours per dunum, as well as the number of regenerated trees during the productive season are independent factors. While productivity is a dependent factor. The optimal quantities of the productive factors included in the estimated model it reached. Including the optimal size of the productivity of a dunum, which amounted to (4734.5) K. g. Which it achieved by approving the budget constraint of (553) thousand dinars / dunum, the specialized efficiency of the productive factors it also measured, and the amount of surplus and the amount of deficit it measured for each productive factor included in the estimated model. It recommended applying the optimal combination of the productive factors to achieve the optimal size of dunum productivity, as well as to educate the producers in order to achieve the specialized efficiency of the productive factors.
