An econometric analysis of table grape in Turkey

摘要

Grape is an important fruit crop among the agricultural products exported in Turkey. The demand for agricultural products, which are the feedstocks of vital food is rising in domestic and foreign markets due to the increase in population. The increasing demand for food can be met by increasing the yield per unit area in agricultural lands. Total cost of the product obtained per unit area needs to be calculated by revealing the elements of production cost to determine the factors affecting the yield. In this study, socio-economic characteristics and cost items of table grape producers in Tokat province, known for the vineyards and grape leaves in Turkey, were determined, and the factors affecting the production cost, profitability and productivity were analyzed. The data were obtained by a survey performed with 130 producers, who were determined using simple random sampling method. Cobb-Douglas production model was used to analyze the factors affecting the table grape productivity in Tokat province. The results revealed that net profit of producers with a production cost of 386.04 dollars per unit land (per decare) is 241.24 dollars per decare. Fertilizer and pesticide costs had the highest share in the cost items and positively affected the product obtained from per unit area. The results demonstrated that land size owned by the producers have a positively effect on the productivity, while the fragmentation of lands has a negative effect.
