The optimal size of wheat farms irrigated by supplementary irrigation of pivot sprinklers is 60 dunums in Salah al-Din Governorate / Tikrit district for the production season 2021/2022.

Abstract

      The research aims to study the reality of the costs of producing the wheat crop in Salah al-Din Governorate / Tikrit District using pivot sprinklers of 60 donum.. The cost function was estimated in the long run by introducing land area as an independent variable in the function in addition to production. The results showed that the optimal area of wheat that achieves economic efficiency and optimal production volumes for the sprinklers under study is (54,655) donum, in contrast, the optimum production was (1076.23) kg / donum. And the average cost per donum (284.405) thousand dinars / donum. Sprinklers also achieved economic efficiency (90%), while the maximum profit production reached (1006.868) kg /donum. Therefore, the study recommends using the optimal quantities of inputs in order to obtain the best production.
