According to research results is established that the fertilizer system including the application N90P40Kg0+Cu+Mn has ensured the maximal size of weight 1000 grains - 6,43 g, at the contents of a crude protein 10,4%. The harvesting of crude protein was in limits from 224 kg/ha in variant without mineral fertilizers up to 338 kg/ha in variant N90P40K90+Cu+Mn. The mineral fertilizer application promoted increasing of the irreplaceable amino acids contents on 11,7%. The sum of critical and irreplaceable amino acids in comparison with variant without fertilizers has increased on 0,74 g/kg and 6,3 g/kg. Entering P80 into preseeding cultivation has led to decrease in the irreplaceable amino acids content in comparison with application P40 and P60. Entering of microfertilizers has promoted increase in the maintenance of amino acids at 1,0%-7,3% in comparison with variants without microfertilizers application. The maximal content of sum of critical amino acids is received in a variant with system of fertilizer N90P40K90+Cu+Mn - 6,50 g/kg of grain. The increase of dozes NPK application does not reduce biological value (amino acid scor, chemical number) of millet grain, and on irreplaceable amino acids the biological value (amino acid scor) of millet grain there is above than norms recommended by FAO/WHO
