Abstract

The potato (Solanum tuberosum) used as a versatile agricultural product and grown around the world under a wide range of climatic and soil conditions is one of the most important staple food crops in Turkey for local consumption, processing and export. Although its alternative usage fields increased significantly, potato production has continuously decreased in the last years since there are major problems stemming from the lack of the effective usage of the production factors. In order to solve these problems, the production factors should be analyzed. The aim of this study is to analyze economic effectiveness for potato farms in Pasinler district, Erzurum by considering the relationship between both input and output. To this end, data collected from a face-to-face questionnaire carried out in 135 potato farms in Pasinler was used for multiple regression and marginal analyses in SHAZAM statistical program. The results of this study showed that the potato growers should increase all production factors (except for the LP and HP) at an increasing rate so that they could achieve a profitable and effective production, and provide the increasing return to scale by considering the marginal analyses and the effective coefficients of the factors in potato production. 

Key words: Efficient coefficients, farm, marginal analyses, multiple regression analysis, potato.
