ECONOMICS AND PRODUCTIVITY EFFICIENCY FOR THE COTTON FARMERS IN THE ASSIUT GOVERNORATE

The cotton crop is the important strategical crop in the Egyptian agricultural and its act main resource of raw material for many Egyptian industries added to its of exported crops. So the aim of this research is studying the production and costs of cotton crop, added to this studying the most important factors affecting the production and the net return of cotton crop at Assiut governorate. The results of research has shown that the cotton area of Egypt and Assiut is taked statistically significant shortly trend reached about 0.033 0.71% respectively, and the analysis variance improved that finding significant difference between averages of the affected factors on the cotton production type among sample categories. As the research has shown that also production functions of cotton crop agree with the statistically and economics Logic and that increasing cultivated area of cotton and amount of machinery labor by rate 1% leads to increasing in the cotton production in this category about 1.16%. And the results of research has shown that the production function for cotton in the third category in the farms of sample also agree with the statistical, and economical logic, added to this they were agree with most important factors affecting the cotton production as : quantity of human labor and machinery labor the total elasticity pointed to increasing this factors by ratio 1% lead to increasing of cotton production in this category 1.09%, as the research showed that the production function at the sample total level were agree with the statistical and economical logic and that the increasing production resources affected in the cotton production as cultivated area with ratio 1% lead 0 increasing in the cotton production with ratio 1.05% . The study showed that the optimum production size in the one ownership category level and total sample are reached about 180.? quainter and the maximum value of net farm returne of feddan was estimated by current price at the ownership categories level in 2005 about 2146.3 LE 1 Farm and the minimum of the farm production which cost 1.6.? quainter farm and the minimum current price covering variable cost of quainter is reached about 396.2 L.E I quainter and the net return of product unit is reached about ?3.8 L.E (quainter.
