In research on sod - podzol loam sandy soil it is established, that optimum of fertilizer is the application N90P40K90 and foliar treatment by microelements (Cu + Mn) in a phase of bushing out in a dose 25 g/ha active substance, which have ensured of productivity 46,3 c/ha of millet grain. The increase due to complete mineral fertilizer application in this variant has made 18,5 c/ha, at recoupment of 1 kg of fertilizers of 8,4 kg grain, at application of microelements (Cu+Mn) on a background of application N90P40K90 the productivity has increased at a level 4,0 c/ha. The given system of fertilization provides grain reception with weight 1000 grains - 6,54 g, and the contents of crude protein makes 11,1%, at the contents of critical and irreplaceable aminoacids 5,45 and 32,19 g/kg of grain accordingly. In an optimum variant on productivity with system of fertilization N90P40K90 + Cu + Mn the sum of critical and irreplaceable amino acids in comparison with a variant without fertilizers has increased on 0,63 g/kg and 6,56 g/kg of grain accordingly. In research the indicator of gathering of protein which is defined by the protein content in grain and productivity was in range from 2,3 c/ha in a variant without fertilizers to 4,5 c/ha in a variant with N90P40K90+Cu+Mn application
