Physiological and biochemical parameters of alfalfa plants (Medicago sativa L.) that were inoculated with mono- and binary compositions of nitrogen-fixing microorganisms were studied in the pot experiment. It is shown that the use of microbial consortium Sinorhizobium meliloti T17 together with Nostoc PTV was more efficient than use of the single rhizobium strain inoculation. This treatment provided an intensification of the processes of nitrogen fixation, photosynthesis and stimulated growth of aboveground plant mass and rhizogenesis, that increased productivity of alfalfa, promoted enlargement of protein content in leaves and improvement of its quality.

Keywords: Medicago sativa L., Sinorhizobium meliloti, Nostoc PTV, alfalfa, nitrogen fixation, photosynthesis, productivity
