Summary. On average for three years grain yield increased from 1.16 to 1.60 t/ha, or 1.4 times, reaching 2-2.1 t/ha in favorable on weather conditions years, on sod-podzol soil. It was due to the application of chemical and biological means. The application of P60K60 is effective without use of the biological preparations; the increases due to rizotorfin usage were registered against the backgrounds without fertilizers and of P60K60, due to mikofil and binary inoculation of seeds–without fertilizers and with N60K60P60. With the use of the biological preparation it was a tendency to an increase in thousand grain weight (by 7-9%). The content of crude protein in lupine grain increased from 31 to 32-33% due to the grain inoculation with lupine cultivation against the background of P60K60. In the case of full mineral fertilizer the biological preparations do not have any effect. The yield of crude protein increases due to the full mineral fertilizer by 37%, due to the biological preparations application–by 14-19%. At the inoculation of seeds by rizotorfin the increase is 36% against the background of P60K60. The maximal yield of crude protein (524 kg/ha, 44% compared to the control) was registered at binary inoculation of seeds and application of N60K60P60. Under the influence of fertilizers and biological preparations in the yield (grain and straw) it is increased the accumulation of nitrogen 1.5 times, phosphorus–1.3 times, potassium–1.4 times. The accumulation of biological nitrogen in the yield (grain and straw) grows due to the biological preparations without fertilizer application 1.34 times, against the background of P60K60–1.14 times, of N60K60P60–1.21 times. After lupine cultivation it is accumulated from 38 to 67 kg/ha of biological nitrogen in the soil, because of biological preparations its amount increases by 26%, binary inoculation of seeds is more effective.
