Estimation technical efficiency of vegetable production farms in lattakia governorate by using maximum likelihood function

The vegetables constitutes one of the main components of plant production, main resources of food security in Syria. The effective of use resources can lower productivity resulting from inefficient use of resources. This research aimed to estimate the technical efficiency of farm and analyze some economic and social factors which effect on technical efficiency of vegetables farms in Lattakia governorate , we used the maximum likelihood stochastic frontier function to estimate the technical efficiency, the model was applied on random sample consist of 50 farms from 10 villages in governorate in 2016. The results shown that there is inversely associated with amount of fertilizer, pesticides, seeds and age of farmer which refers to waste of using this resources, while the associated with size of farm, manual and mechanical labor was proportional .the average of technical efficiency was 66% this result indicate that the farmers can increase their production 34% more by using the same amount of resources and reach to technical efficiency.
