Abstract
Abstract Studies in estimating the production and cost function are considered as important in agricultural sector. They have an important role in research and estimating the function in agricultural researches. The importance of the research revealed from its importance in estimating the production and cost function for the wheat crop in Nineveh Governorate. This method is one of important approaches, by which it can be easy to estimate the optimum amounts of production and cost. This research aims at estimating the production and cost function of wheat in the guaranteed, semi – guaranteed and non-guaranteed of rain fall regions during agriculture season 2005-2006. The research depended on the hypothesis that is the producers of wheat in Nineveh Governance lacking the optimum usage of producing resources according to the technical and pricing level, which affect the size of production and cost. In order to approve these hypotheses, econometrical model has been applied in many ways by using simple and multiple regressions with (OLS) method. The following results have been revealed that there is shortage in using land resource, labor and capital in the three rainfall areas. This has been proved through the shortage of the producers in these areas in achieving the optimum production of wheat. The applied section at the research showed that optimum volume of wheat production has been reached 1.157, 0.618, 0.117 ton/donum, whereas the cost of production has been reached 74485, 61165, 104145 Iraqi dinar per ton in the three types of rain full regions. .
