التحليل الاقتصادي لتكاليف إنتاج الذرة الصفراء في قرية المصلحية : دارسة ميدانية 2010

Abstract EN

The research aims to identify the structure of the production costs of maize Zea mays L.

to a village self-interest, depending on the data field for farmers in the crop in the village of self-interest in the district of Tarmiyah.

The study included 25 farmers for the season (2010) grew 100.5 hectares produced 491.4 tons, which represents all the farmers who grow the crop in the village of self-interest of to spend Tarmiyah.

Was adopted by the Economic and statistical analysis and standardization of data Alaolipohart results show that fixed costs were 0.234% of the total overall costs and the costs of family work is the highest proportion of costs at all as they hit 86% of the total fixed college.

Aohma reflects the importance of the family business as a parameter for the production of this crop.

Were estimated as a function of the total costs and were in accordance with the logic of economic theory, where the specimen is a cube Alaktramlaimp of the relationship adopted in the research and for compatibility with the statistical tests, standard and economic development.

Has proved to be significant function at the level of probability 1% was the value of F calculated is equal to (300) and proved to be significant parameters estimated and the signal parameters were identical with the concept of economic theory.

Show that the high proportion of the interpreter to 98% according to the coefficient of determination (R2) was confirmed not there is a problem autocorrelation between the values of residuals of a specimen according to Durbin Watson test.

Also overcome the problem of instability of the specimen variation depending on the park and test this function was derived function Alclepwalklvp marginal average cost to calculate the optimum size.

Show that the optimal size of production, which maximizes the profit is 79.5 tons, while the actual production of the sample is 19.66 tons.

Was also reached to the space that best achieve optimum production and found to be of 16.25 hectares of the research sample, while the real rate of the cultivated area of 4.02 hectares already so it must expand in the area planted to this crop to expand production optimization.

Calculated the lowest possible price to offer the product in his product from the calculation of the average total cost estimated in the long term which is (104.67) one thousand dinars per ton.

Function was derived in the long term supply and economies of scale achieved the expense of flexibility and cost and price elasticity, which has been weak due to the weak response of farmers to change any prices that are facing great difficulty in controlling production in the case of price change.
