Abstract

The research aimed to estimate the wheat crop production function to determine the relationship between the optimal combination of using productive resources (labor and capital), in order to reach the optimal production level. A random sample of (70) pivot sprinklers of (60) dunums was selected. The Cobb-Douglas function was estimated for the wheat crop irrigated by spraying in Salah al-Din Governorate using (SPSS23) program. It turns out that the average amount of work, which is (9.1) workers/day, is greater than the optimal amount of work in the sample, which is (6.314) workers/day. As for the amount of capital resource at its average in the research sample, it reached (264.041.34 thousand dinars), which is greater than the optimal quantity of capital resource, which amounts to (237.579) thousand dinars. Therefore, if the farmer wants to achieve optimal production, he must reduce the amount of work and capital used to achieve to the optimal amount of production. The optimal production in the sample was (905.39) kg, while the average production was (1028.6) kg. This means that the amounts of work and capital used must be reduced, to achieve economic efficiency and then raise production to the optimal level. The net profit is 357.235 thousand dinars. This means that the farmers obtained a higher net profit from using the optimal quantities of the labor and capital components compared to the quantities used by the sample farmers.
