The influence of chemicals on productivity and quality of potato tubers cv. Kurazh cultivated on sod-podzolic sandy soils under radioactive contamination was studied in the south-west of the central Non-Black Soil Zone of the Russian Federation. Organo-mineral system (manure, 40 t/ha + N75P30K90) applied in complex with chemicals and biological agent Gumistim turned to be the most effective fertilizer system providing the maximum potato yields during the experiment. Moreover, complex application of the chemicals increased protein level and decreased starch content in tubers, it also improved amino acid composition; concentration of heavy metals and specific activity of cesium-137 did not exceed sanitary and hygienic standards (SanPiN 2.3.3 1078-01).
