In a field experiment on sod-podzolic sandy radioactively contaminated soil, the effect of mineral fertilizers of various degrees of saturation and non-root treatment with the growth stimulant Albit on the yield and quality of millet grain of the Quartet variety was studied. The positive effect of increasing doses of nitrogen and potash fertilizers in the composition of NPK on the yield, biological and technological indicators of the quality of millet grain has been established. The maximum yield of 4.61 t/ha and the collection of crude protein of 0.622 t/g were obtained from the background of N120P60K120 in combination with the growth stimulator Albit. The applied fertilizer systems contributed to an increase in the crude protein content from 11.0% in the control to 13.5% according to the experimental variants and an increase in the total amount of amino acids in millet grain. The largest grain size is 781 g/l, the mass of 1000 grains is 7.9 g, the yield of cereals is 86% and the lowest film content is 11.2% were obtained using the N120P60K120 variant in combination with the growth stimulator Albit. The concentration of residual nitrates in millet grain did not exceed the MPC. The specific activity of 137Cs in millet grain under the influence of the studied chemicalization agents decreased by 1.1 - 3.3 times.
