The paper uses data envelopment analysis to compute overall technical and input-specific technical efficiency measures of conventional and organic raisin-producing households in Turkey. The questionnaires were applied to fourty-four organic and thirty-eight conventional producers determined by stratified random sampling. For each household group the average cost efficiency and technical efficiency coefficients are determined to be 0.712 and 0.862 for organic households, while 0.844 and 0.903 for the conventional group. According to the coefficients calculated for individual and different returns to scale, it can be stated that conventional households are on average more efficient relative to their own technology.

This study aims to identify the income level required for agricultural enterprises to achieve economic sustainability. The theory behind the equation used to calculate a sustainable income is explained. The ecological, technical, social and economic components of sustainability in agricultural enterprises have been identified and discussed and the importance of economic sustainability in terms of achieving total sustainability has been emphasised. Economic sustainability was divided into three components incorporating the income needed to meet the cost of living and to address depreciation and interest costs for the enterprise. Those enterprises that achieved this income level were determined to be economically sustainable. For this purpose, data was collected by using a face-to-face survey method with 181 agricultural enterprises operating in Konya and analysed in line with the purpose of the study. According to the results of our analysis, it was observed that more than 150 enterprises were not sustainable.
