The main objective of this research is to determine profit efficiency of greenhouse tomato farms in Antalya province. In the scope of this research, socio-economic characteristics of farms, physical input usage in the greenhouse tomato production, revenue levels and gross and net profits attained towards production activities were determined. In order to analyse efficiency of greenhouse tomato production a "stochastic profit frontier" model was used in the study. The level of inefficiency for fall, spring double crop and winter single crop production periods was estimated with the stochastic translog profit function. According to the economical analysis results, single crop tomato production was found more profitable than double crop tomato production. According to the model estimation results, the profit inefficiency rates for fall, spring and winter production periods were calculated as 0.158, 0.210 and 0.169 respectively. There are significant differences among greenhouse holdings in terms of technical and distributive efficiency.
