Abstract EN

Cotton's crop is considered to be one of the strategic crops in Iraq, it is an important sources for fibers which are used in textiles as will as using its seeds in vegetable oil industry.

It is one of the important irrigated crops in Nineveh province.

Due to the cost increase and decrease in production size and the remot production than the optimum size.

these all affected the acre yield .

thus,we tried to understand to what extent can the farmens achieve size economies through field data which included (30) farmers representing 8.57% from the contracted farmers with the national program to develop cottons agriculture for the season 2005 .

It is clear from studying productive situation for the period (1988-2004) that there is an expansion in cultivated area production and productivity with the positive annual growth rate about (0.01,0.06,0.07) respectively .The statistical analysis for the applied example has shown that there is an opposite relationship between farms size and productivity and also the function of costs was cubic and the best size for production in long – run is 12.39ton .

is for the optimum area it can be exploition it form cottons farmers is 25.52 acre .

Therefore, it is necessary to use modern technologies in production which contribute in increasing the yield in order to fill apart of the country's need from this crop .
