In research spent on sod-podzolic light loam soils influence of mineral fertilizers and physiologically active substances on change of an index of a leaf surface, accumulation of biomass and formation of the yield of roots of sugar beet has been studied. Application of mineral fertilizers increased the area of leaves by 78%, jointly with physiologically active substances on - 96-114%. The quantity of biomass under the influence of mineral fertilizers has increased up to 34,7 c/ha. Application of physiologically active substances has allowed to generate in addition 12,1-14,9 c/ha. Use of various levels of a mineral nutrition has promoted increase in productivity of root crops on 15-25%. The additional increase in productivity of root crops from action of physiologically active substances has made 6-41 c/ha. Entering of preparation Novosil in inhibitor dose 500 ml/ha has increased in productivity of root crops of sugar beet on 22-31%
