Crop-based land suitability studies constitute an important component of precision and sustainable agricultural practices. In this study, a model was created to determine suitable lands for peach farming with the use of the analytic hierarchy process (AHP). The land suitability model was carried out in Derekolu region of Bayramiç town of Çanakkale province. Within the scope of the study, a total of 12 parameters, namely soil depth, soil texture, EC, pH, organic matter content, CaCO₃ content, nitrogen, phosphorus, potassium, elevation, aspect, and slope, were used. Present assessments revealed that of the assessed lands, 367.50 ha was highly suitable, 7085.25 ha moderately suitable, 6341.25 ha marginally suitable, and 378.50 ha not suitable for peach cultivation. Texture, slope, and CaCO₃ content were respectively identified as the most effective factors in peach cultivation. The combined use of AHP and GIS techniques in the identification of suitable lands for peach farming facilitated assessments and provided significant advantages in terms of time and economic aspects. Further research is recommended to test the validity of the present model for different geographies under different climate and soil conditions.
