Özet
In Turkey, which ranks the 10th country worldwide in the sunflower (Helianthus annuus L.) production, 55% of the production is carried out in Thrace Region. Therefore, agricultural enterprises in Thrace Region, situated in the European part of Turkey have specialized in producing sunflower, and have become the centre of vegetable oil industry in the region in terms of produced raw material. This research was conducted in 182 agricultural enterprises in 3 provinces of Thrace Region in Turkey and its objective was to determine input/output relations in sunflower production. The study indicates that the determination coefficient (r(2)) derived from Cobb-Douglas production function was significant at 0.01 level and the elasticity coefficients of the variables (except chemical fertilizer) were found (beta(i)) positive in derived equation. It was determined that the variable of herbicide cost had the highest value of the marginal effectiveness coefficients and none of the variables was used at economically optimal level in the study area. When the Marginal Technical Substitution and the Price Rates were taken into consideration, it was noted that only the seed cost/hoeing cost was closest to economically optimum level (1.10). According to stepwise analysis the Land Renting Value was determined as the most important variable in sunflower production.
