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 prov
ince. 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.
The aim of this research was to measure the technical efficiency of cotton farms
with surface irrigation system using Data Envelopment Analysis (DEA) in the field
school in Idleb governorate. Preliminary data was collected based on field surveys,
and random sampling. 34 farms in the villages of Meless and Segar were chosen
for the season 2014.
