Summary:

In this study, it was aimed to compare the economic aspect of different applications of composts obtained from solid wastes of rose oil processing (RC) applications in organic apple production. The data used in the study were obtained from the experiments carried out in Egirdir Fruit Research Institute of Food, Agriculture and Livestock Ministry, Turkey. The trial was carried out with a total of 6 applications consisting of 5 different nutritional applications (RC, ERC (50%) (half dosage of the enriched RC, ERC (100%) (full dosage of the enriched RC, AB (azotobacter), and ST (standard application: 50% commercial solid organic manure +50% commercial liquid manure)) and 1 control (no nutrients applications). According to the results of the research, it was determined that apple production in all treatments was higher than control application. The result showed that the highest yield was determined for ERC (100%). The production costs per decare of the organic production in all treatments were found to be higher than the control application. Production cost was 854.97 USD da-1 in control application, while it varied between 914.61 USD da-1 and 984.79 USD da-1 in all treatments. When a comparison was made in terms of net profit, it was determined that the most advantageous application was ERC (100%). The net profit per decare for the ERC (100%) application was determined as 214.35 USD. In the control application, net profit per decare was determined as 130.42 USD.
