The aim of this research was to estimate production costs, and to compare technical efficiency levels and production gap of wheat, barley and lentil in the area within the project of enhancing food security in Arab Countries/Syria-Second Phase. The search conducted at Jabal Samaan region based upon 150 Questionnaires. The technical efficiency estimated by stochastic frontier analysis using Front 4.1 software. The results indicated an increase in the variable cost percentage of the total costs. The net profits were 650128, 458686 and 320021 S.P/ha for lentil, barley and wheat respectively. Averages technical efficiency were 81.5%, 67.3% and 82.9% for wheat, barley and lentil farmers respectively. Also, high significantly differences were found between actual and potential yield. Besides, lowest production gap was 340.3 (kg/ha) for lentil farmers, followed by wheat farmers (785.1 kg/ha), and finally barley farmers (1611 kg/ha).

Key Words: Production costs, Technical efficiency, Stochastic frontier analysis, Jabal Samaan.

The aim of this research is to estimate the technical efficiency levels, wheat production, and cost functions in the work area of “Enhancing Food Security in Arab Countries/Syria” Project. The research was conducted at Al-Bab region depending on 123 Questionnaires. The results revealed that variable costs represented about 67.49% and 65.45% of the total costs for both irrigated and rainfed wheat, respectively. The variable costs are also responsible for the variation the irrigated wheat yield by about 73.7% according to the stochastic frontier production function. The technical efficiency was (92.7%) for irrigated wheat and (79.7%) for rainfed wheat. In general, the technical efficiency of the sample was high, and this is an indication of the experience of the farmers in growing wheat crop. According to the estimates of cost functions, the optimum production accompanied with the lowest costs was 6946.4 kg/ha for irrigated wheat and 2422.2 kg/ha for rainfed wheat.

Key Words: Technical efficiency, Stochastic frontier analysis, Variable cost, Cost functions, Wheat, Syria.
