Relevance. Chicory root (Cichorium intybus) is a very valuable technical, vegetable and medicinal crop. The development and improvement of a scientifically based fertilizer system is one of the most important issues in agricultural production, since it determines not only the level of crop yield, but also the direction of changing, increasing and preserving soil fertility in general.Material and Methods. The aim of the research was to identify the most effective doses of mineral fertilizers and methods of their application (basic and top dressing) to ensure maximum yields of root chicory root crops. The research was carried out in 2021-2022 in the field of the Rostov Vegetable experimental station on chicory – Branсh of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center. Chicory seeds of the Petrovsky root variety were used for sowing. Mineral fertilizers were applied in the form of azophosphate and potassium sulfate.Results. On sod-podzolic soils, the use of mineral fertilizers had a positive effect on the yield of chicory root crops. The more developed the leaf rosette of plants, the higher the yield of root chicory.Conclusion. In the soil and climatic conditions of the Non-Chernozem zone of the Russian Federation, the greatest effect from the use of mineral fertilizers on root chicory is observed with a mineral nutrition system that includes the main application at a dose of N60P60K60 and top dressing at a dose of N60P60K60.
