英文摘要	Tunisia is being faced with severe challenges in increasing wheat production in order to enhance the self-sufficiency ratio for wheat production. Using Data Envelopment Analysis (DEA), this paper provides an evaluation of the performance of a sample of rainy Durum Wheat producers in the region of Zaghouan (center of Tunisia) in upper semi-arid by means of overall technical, pure technical and scale efficiency and the performance of the average production unit. The factors which influence the efficiency scores in rainy wheat production, have been also determined using a Tobit model. Data were collected from 105 farms in 2015-2016. Results of study revealed that technical rather than scale inefficiency is the main source of productive inefficiency. The average overall technical, pure technical and scale efficiencies are 58%, 73% and 81% respectively, indicating that production efficiency can be improved by 42% without having to increase their input's utilization. Most farms, 74.3% operate in increasing return to scale while 12.4 of them have decreasing returns to scale and only 13.3% are scale efficient. Hence, the farmers need some adjustments in their use of production inputs in order to operate on the optimal level. Results of Tobit model analysis showed a positive effect of the education level of farmers, farm size, main occupation, and technical package set including variety, nitrogen use, herbicides, pesticides and previous crops which are important policy variables and determinants of efficiency which can be integrated into the agricultural policy in Tunisia in order to raise the current level of productivity, food security and hence the sustainability development.
