TECHNICAL EFFICIENCY IN GRAPE PRODUCTION: A CASE STUDY OF DENIZLI, TURKEY

WOS: 000454318300030In many parts of the world, viticulture has become primary agricultural importance throughout history. The main reason for this is that it is economically productive with an assessment of grapes as fresh wine, dried fruit, fruit juice and other manufactured products. The aim of this was to determine the resource utilisation success of vineyard in Denizli province, which has an important share in Turkeys grape production. The primary material of the study was the data obtained from the grape producers in selected villages in Civril, Cal and Buldan Districts of Denizli Province. The sample size was calculated by using proportional sampling method. Sample volume was found 96 farmers in 95% confidence interval and the 10% margin of error. Data envelopment method (DEA) was used in the research to measure technical efficiency in grape production. Data Envelopment Method is used to evaluate the efficiency of a certain number of production units. The technical efficiency, scale efficiency and pure technical efficiency calculated according to input and the results were calculated and compared to irrigated and non-irrigated vineyards. Interviewed producers were 49 years old, educated seven years, and their agricultural experience was 26 years. According to the findings, respondents were asked how much they could reduce their input on the efficiency limit, and some suggestions were made for inefficient vineyards
