Abstract: This work aims to differentiate the rural land of Slovakia in view of the possibility of effective sunflower growing. The differentiation is based on pedo-climatic and production-economic parameters. Soil categorisation took into account the correlation between the site properties (soil and climatic conditions) and the biological and agrotechnical requirements of the crops. Sunflower requirements were included in yield databases using software filters such that a given site property excluded or limited sunflower growing, which was reflected in predicted production. The prediction was subsequently interpolated into four suitability categories: soils unsuitable for sunflower growing, less suitable soils, suitable soils and very suitable soils. A map of categories of soil suitability for sunflower growing was created using a Geographic Information System on the distribution of soil parameters in Slovakia. According to our calculation in Slovakia, 18.8% of farmland is very suitable for sunflower growing, 24.9% is suitable, 16.6% is less suitable, and 39.7% is unsuitable for sunflower growing. These categories are characterised and specified in detail in the paper in terms of geographical, soil, climatic, production and economic parameters. The analysis of the actual sowing of sunflowers between 2018 and 2021 showed that 51% of the areas were located in very suitable soils, 32% in suitable, 10% in less suitable soils and 7% in unsuitable soils for cultivation.
