The effect of microbiological preparations on straw destruction and sugar beet yield under the conditions of chernozem soils in kursk region

The effect of microbiological preparations Gribophyt and Imunazot on microbiological activity of typical chernozem, winter wheat straw destruction and the yield of the succeeding crop of the crop rotation, i.e. sugar beet, was studied. It is found out that the treatment of straw with a bacterial-fungi complex (Gribophyt, 7 L/ha+Imunazot, 3 L/ha) after 90 days of exposing (August-October) increased microbiological activity of the soil by 16.4 %, facilitated 30.6 % of wheat straw destruction, or by 9.8 % higher than that in the control variant. The application of the bacterial-fungi complex (Gribophyt, 7 L/ha+Imunazot, 3 L/ha) for the straw treatment, and also for two-fold treatment of sugar beet in the phase of filling rows and in the phase of filling interrow spaces (Gribophyt, 3 L/ha+Imunazot, 3 L/ha) increased sugar beet yield by 4.3 t/ha in comparison with the yield in the control variant equal to 51.6 t/ha. The application of the bacterial-fungi complex Gribophyt+Imunazot when treating winter wheat straw and two-fold sugar beet treating was economically profitable and ecologically reasonable.
