This research aims to measure the efficiency in agricultural enterprises producing sunflower oil in
Thrace Region and also to determine the causes of inefficiency. The data of the study have been
obtained from 571 agricultural enterprises, which have been determined by using the Stratified
Sampling Method, producing sunflower on an area of approximately 5400 hectares. Stochastic
Frontier Analysis method has been used to measure the technical efficiency scores of the enterprises
examined in the study. Data regarding five inputs is used in the function for Stochastic Frontier
Analysis. Also five variables have been included in the technical inefficiency model. According to the
results of the analysis, the efficiency scores of the examined enterprises ranged between 0.29 and 0.96,
while the average efficiency score has been obtained as 0.80. According to these findings, an average
enterprise predicts that sunflower yield can be increased by 17% without making a change in the
amount of input it uses. However, it has been calculated that the enterprises operating at a minimum
level can increase the sunflower yield by 70%. In the recent study, it has been determined that the
sunflower yield per unit area is positively related to the use of seeds, labor and fuel, whereas it is
negatively related to the use of fertilizers and pesticides. Findings, which have been obtained in the
study, state that increasing the amount of seeds, labor and fuel will raise the amount of sunflower
produced, while increasing the amount of fertilizer and pesticides used will cause a decrease in the
amount of sunflower obtained. In the study, according to the γ parameter calculated for the
inefficiency model in oil sunflower production, it has been concluded that 91% of the variation in
sunflower yield is caused by technical inefficiency. The coefficients of age, education and number of
parcels in the inefficiency model are negative. This situation indicates that those enterprise owners
who are older, have a higher education level, and have more parcels are more effective. However, the
results of the research have revealed that the coefficient of the sunflower cultivation area variable has
a positive sign and the inefficiency increases as the cultivation area raises in the examined enterprises.
