الملخص EN

The research aimed to measure the economic and technical efficiency using analysis of the random border production function (Stochastic Frontier Analysis) for cotton farms irrigated by surface immersion way in Qamishli district in Al Hassakah province.

Preliminary data for 89 farms spread over 12 villages were collected on the basis of field survey using the stratified random sample in selection the research sample.

Results showed that the value of the gross margin per unit area amounted to about 10308.4 SP /dunums and the value of the gross margin per unit was 0.63 SP.

It was found that the variable costs were responsible significantly for 38% of the change in the return and farms are still in the phase of yields increased.

This indicated that cotton farms had reached the stage of diminishing returns and the yield size was negative.

Thus, it is not anymore recommended to increase the cotton production irrigated by surface way.

It was also found that the average value of the technical efficiency of farms amounted 88.58% and the largest number of farms had achieved a technical efficiency higher than the average in the studied sample.
