The purpose of the study is to determine the efficiency of greenhouse strawberry production in the province of Aydın, which has an important position in Turkey’s strawberry production. The main material of the study consists of the primary data collected via the survey method from 59 greenhouse strawberry producers in Aydın province. Neyman Method, one of the stratified sampling methods, was employed to determine the number of surveyed producers. The data was collected through face-to-face interviews with the producers. In the study, input-oriented Data Envelopment Analysis (DEA) was conducted to establish the technical efficiency of the producers. The relationship between some selected socio-economic variables and producers’ efficiency scores was also investigated by Tobit Regression analysis to identify the factors causing inefficiency. According to the research results, the mean efficiency of the producers was 0.62 for constant return to scale, 0.98 for variable return to scale, and 0.63 for scale efficiency. Mean efficiency levels of the producers were found to be high under the assumption of the variable return to scale. It was also determined that they were able to evaluate the inputs they used at a rate of 98%. In this case, the producers will be able to reduce their inputs by 2% without changing the output amount. It was seen that there was a positive relationship between efficiency and strawberry yield and certified seedling use (P<0.05); and a negative relationship between efficiency and producers’ age and labour use (P<0.10). These relationships were statistically significant. Finally, a negative relationship was found between fertiliser use and efficiency, but it was not statistically significant (P>0.10).
