DOI : 10.21566/tarbitderg.437180 - The suitable lands for double crop soybean cultivation were determined by means of this study to shape the optimal use of the agricultural lands and crop planning to cultivate more than one crop from a unit of land. Most important factor governing the distribution of potentially suitable lands in a region was determined the weighted ratios of inter effects of ecological criteria required in crop production. GISbased Analytical Hierarchy Process (AHP) technique was applied to determine the weighted effects of the main criteria (i.e., climate, topography and soil) and their subcriteria (vegetation period, total effective temperature, average temperature of July and August, elevation, soil depth, land use capability classes) and potential suitablity classes were identified, in this research. According to the research results, 7.65% (5 968 013.35 hectare) of the study area is found to be highly suitable, 4.70 % (3 666 170.55 hectare) to be modarete suitable, 8.43 % (6 584 410.16 hectare) to be less suitable, and 79.22 % (61 839 407.74 hectare) is not suitable for double crop soybean cultivation.
