The role of rhizospheric bacteria in the formation of photosynthetic apparatus and productivity of winter wheat in the conditions of the Left Bank of the Saratov region
The article discusses the ability of strains of plant-stimulating rhizobacteria (plant-growth-promoting rhizobacteria, PGPR) Azospirillum baldaniorum Sp245, Azospirillum brasilense Sp7, Azospirillum brasilense SR80, Azospirillum brasilense SR88, Azospirillum brasilense Cd, Ochrobactrum cytisi IPA7.2 and Enterobacter ludwigii K7 to stimulate the growth of the assimilation apparatus and productivity of winter soft wheat of the Novoershovskaya variety in the conditions of the Left Bank of the Saratov region. The bacteria stimulated the growth of the assimilation apparatus of plants, in addition, the bacteria of the genus Azospirillum as a whole more significantly increased the net productivity of photosynthesis. As a result, bacterization significantly increased the yield of winter soft wheat by 11-27,7%.
