Abstract
This research aims to study and estimation of quantities optimum (labor and capital) used by farmers crop in the province to achieve levels of various production and how close these quantities with quantities sizes actual farmers crop, urged farmers to adopt these quantities and of the study in order to achieve better profits resources available to farmers, and sizes through the use of Cobb Doclas and derivatives economic reached us that the of sizes production at the break-even point is 1764.43 kg / don and the amount of work that achieved is 9.86 man / day and the capital needed for this size is 120,676.54 dinars, while the actual size for the production of sample 2367 kg / don and the amount of work that achieved amounted to 25.5 man / day and the capital needed for that reached 733,146 dinars, while the optimal size of the production, which minimization costs amounted to 2956 kg / don and quantitative optimumof labor that necessary to achieve reached 17.38 man / day and the amount of capital optimization necessary to achieve was 514,059 dinars, while the size of production maximization profit amounted to 2569 kg / don which is less than the size of production optimization because the lack of response price levels to expand production and the fact that farmers working in the short run, while quantitative optimization of work that maximizes profit amounted to 26.82 man / day and this confirms properties in the short run, and quantitative optimization of capital that maximizes profit amounted to 205,569 dinars and this confirmation that the farmers were producing in the short run because of the lack of response of capital to expand production, and where the response was only in work resource and this is confirmed by economic theory, and show that the greatest net grossing farms if the produced when the optimal size only reached in the study 542,275 dinars, while the when-sized maximization profit 125,700 dinars, and he was the size of the production sample 37,997 dinars, and the results achieved net profit shows us that the amount of profit increases with the level of production but more than the net profit at the optimum size of production and this is due to the fact that the total costs when the optimal size is the lowest possible, and noted the decline in production and net profit at size maximization profit and the reason is attributed to the production has been in the short run, it did not exceed the production optimum size added to the escalating costs of production after the optimal size and the lack of response output prices to expand production, which led to a decline in net profit at size maximization of profit achieved in this study, but values the marginal rate technical(substation) stood at breakeven point 16018.33 and when the size of the production sample amounted to 9092.10 and when the maximization optimal size of production amounted 6196.89 while the maximization profit 5891.90, and demonstrate the value that it is positive and decreases whenever expansion of production and this shows that the production in the second stage, and also study proved that outputs marginal both labor and capital equal to efficiency variable element at constant other element when the average arithmetic and also enunciated tables (1.2), and also proved that all values averages labor and capital is the largest of the values of outputs marginal both elements in tables (1.2), while the levels productivity was 602.57 kg between breakeven point and the size of the production sample and long productive between The production of the sample and the optimal size of production has reached 589 kg, while the - 387 kg between optimal size of production and size maximization profit, which underlines the lack of response to the expansion of production due to curb price levels outputs well as high production costs and the fact that production has been in the short run, it was worth less of the value of the optimal size of the production
