Purpose: The main purpose of this research is to reveal the preferences of farmers for input supply and sales of agricultural products, interpreting the differences in this field and suggesting solutions.Design/Methodology/Approach: The main material of the research is the survey study conducted with the producers in the research area. Apart from the survey data, the Farmer Registration System (ÇKS) data recorded by the Ministry of Agriculture and Forestry in the field of crop production was used. The records of the producers surveyed from the data of the National Milk Registration System were determined and included in the data set. Results were evaluated with descriptive statistics and Likert scale.Findings: It has been determined that farmers prefer agricultural credit cooperatives and dealers for input supply, whereas they work with traders in the sale of agricultural products. In addition, it is observed that the agricultural sales or agricultural development cooperatives established to provide cheap input to the farmers are insufficient in this area.Originality/Value: For farmers to have cheap inputs and low financing costs, the cooperatives operating in this field should be more institutionalized. In order to ensure the preference of cooperatives in terms of product sales, both information activities and strict controls of the state should be expanded.
