Results of researches have shown, that the greatest productivity of grain of barley (35,3-46,3 c/ha) and oats (35,2-46,4 c/ha) is received at entering mineral fertilizers application in doze N90P60K120 on all soil types. Advantages has not been revealed at fractional entering of nitric fertilizers application in doze N60+30. Probably, it has been connected with insufficient provision with moisture supplying during top dressing (tillering - an output in a tube). At fertilizers application under lupinus angustifolius of Edelweiss variety in doze P40K80 the increase of a grain crops on sod-gleyey soil has made 6,1 c/ha, on sod-podzolic soil - 4,7 c/ha. The increase in doze of phosphorus and potassium (Р60К100) has led to increase of a grain yield on sod-gleyey soil on 7,7 c/ha, on sod-podzolic soil on 9,3 c/ha. Application of a starting doze of nitrogen (N15) has not rendered essential influence on productivity of grain on all soil types. Both mineral, and organic fertilizers (P60K120N80P60K120, N80P60K120 + 50 t/ha manure) were brought under crops of corn hybrid Bemo 182 СВ). The greatest crop of green weight is received at combined organic and mineral fertilizers application on peat-gleyey (667,0 c/ha), sod-gleyey 494 c/ha and sod-podzolic (550,4 c/ha). The greatest effect from application P60K120 application was observed on peat-gleyey soil - 594,2 c/ha (the control - 480,8 c/ha)
