ESTIMATION OF TOMATO PRODUCTION FUNCTION IN BAGHDAD GOVERNORATE FOR THE SUMMER PRODUCTION SEASON (2020) *

Abstract

A questionnaire was prepared to collect data from the tomato producers in the Governorate of Baghdad, Data included the variables related to the suppliers of production (capital and labor), as well as data collected through summer season (2020), The amount of the capital resource per acre of the tomato crop was estimated in the unit (thousand dinars), As for the labor resource, it included human work, which included family work and wage work, and the percentage of wage work constituted (43%) of the total human work. As for family work, it constituted a rate of (57%). The family was great importance cultivation and service operations of the crop within the scope of the studied sample. The elasticities values for all levels of productivity are almost constant, and the elasticity of the variable productive resource work (L) was equal to its elasticity in the estimated function and its value (0.211), which confirms the validity of the results obtained, This means that the flexibility of response to the resources used is less than the correct one, which indicates an increase in production in decreasing rates, and thus it falls in the second stage of production .And the elasticity of the variable productive resource capital (k) was equal to its elasticity in the estimated function and its value (0.431), and the total production elasticity, which represents the sum of the elasticities of response to the resources used, which represents capacity returns, Its sum was less than one (0.641), which indicates that the increase in resources by a certain percentage is offset by an increase in production by a lower percentage, ie, the diminishing capacity. The optimum quantities of labor and capital were calculated at the optimum production volume, and the amount of work needed to achieve the optimum volume of the crop was (13.4) man/day. As for capital required to grow one acre of the crop (464,239.55), the optimal volume of production in the optimal combinations of (L.K) was (4823.77), and the total production costs amounted to (644,663) and these results are consistent with the logic of the economic theory.

Keywords: production function, production flexibility, production resource.
