Determination of Technical Efficiency in Seedless Raisin Production

In this study, technical efficiency scores of producing enterprises in Manisa, Izmir, and Denizli provinces, where almost all the seedless raisins are produced in Turkey, were determined. Efficiency calculation was made with the data envelopment method and data from 150 enterprises for the 2020 harvest year were used. The reason for the difference in productivity in the & Ccedil;al and Bekilli districts was explained with the metafrontier analysis approach, and efficiency analyses were carried out by grouping 33 enterprises in this region as the & Ccedil;al group and the others as Ova group. It was determined that the average efficiency score (crste) of the Ova group was 0.726, and the average efficiency score (crste) of the & Ccedil;al group was 0.815. The reason for the difference in productivity in the & Ccedil;al group is due to the difference in production technology. It has been determined that the enterprises in the Ova group represent the metafrontier (upper limit) technology. The enterprises in the & Ccedil;al group have a production technology that limits their production, and the maximum output they can produce is 56% of what they would achieve when they use the upper-limit production technology. In the plain group, 16 enterprises that achieved technical efficiency (crste) yielded 591.12 kg in one decare of production area, used 132.26 Turkish Liras fertilizer, 408.84 Turkish Liras pesticide, 6.89 male labor force, and 25.5 liters of diesel oil. In the & Ccedil;al group, 15 enterprises that reached technical efficiency (crste) yielded 127.88 kg in one decare of production area, used 73.51 Turkish Liras fertilizer, 91.90 Turkish Liras pesticide, 3.71 male labor force, and 16.0 liters of diesel oil.
