During the field experiment, the effect of potash fertilizers on the yield and quality indicators of the green mass of millet was studied. It was found that the highest yield of green mass (13.4 t/ha) and grain bearing (12.3 t/ha) on average over three years of research was provided by a dose of potassium fertilizer 240 kg/ha. The maximum volume of crude protein (0.27 t/ha), dry matter (3.1 t/ha) and metabolic energy (26.3 GJ/ha) were also obtained with the addition of K240. The specific activity of 137Cs in the products obtained in the experiment did not exceed the sanitary and hygienic standard (400 Bq/kg). Potash fertilizers reduced the intake of radionuclide into the crop. The minimum value of this indicator was noted in the variant with the addition of potassium at a dose of 240 kg/ha of active substance.
