The experimental data concerning the main nutrients content in millet straw and grain in depending on fertilizer system are presented. At cultivation of millet of grade Galink on sod podzolic sandy soils at organo-mineral system of fertilizer application with entering N60P40K90 on background of organic fertilizers (7,5-15,0 t/ha) productivity of grain at a level of 30-33 c/ha with a recoupment of 1 kg NPK up to 5,9 kg of grain is received. Inclusion of carbamide with a regulator of growth of plants hydrogumat or complex NPK fertilizers with a regulator of growth of plants phenomelan in millet fertilizer system provides an increase of grain from 1,6 up to 3,8 c/ha in comparison with standard forms of fertilizers. Carrying out of elements of a feed by a crop of millet at organo-mineral system of fertilizer makes: nitrogen - 56,9-72,9 kg/ha, phosphorus - 42,5-48,1, potassium 86,5-131,9, calcium - 10,7-13,0 and magnesium--12,7-15,3 kg/ha; in straw of millet collects, nitrogen--16,5-26,4 of kg/ha, phosphorus--13,9-21,6, potassium-72,7-122,1, calcium 4,2-6,3 and magnesium - 6,6-9,1 kg/ha which can be used by agricultural crops as fertilizer at straw ploughing. Data on specific carrying out of elements of a feed with a crop of millet are cited (carrying out with 10 c of basic product) can be used for calculation of dozes of fertilizers for a planned crop and make on the average: nitrogen - 20,1kg, phosphorus - 14,7, potassium - 32,8, calcium - 3,8, magnesium - 4,3 accordingly
