Influence of pre-sowing seed treatment with nanostructured bentonite on qualitative and quantitative green biomass indicators of alfalfa

There were revealed effectiveness of nanostructured bentonite as a means for pre-sowing treatment of alfalfa seeds during field experiments on the gray forest soil of the Tatarstan Republic. An increase the parameters of germination of seeds, an acceleration of the phenological development of plants, an increase in the yield and quality of green mass of alfalfa in terms of the content of crude protein, fiber and basic macroelements have been established.
