FIELD: chemistry.
SUBSTANCE: invention relates to microbiological fertilisers for plants, specifically to a microbiological composition based on Rhizobium (symbiotic nitrogen fixer) legume bacteria. The composition contains Rhizobium lupini bacteria and associative nitrogen-fixing bacteria Flavobakterium, with components in weight ratio of 1.0-1.5:1.5-2.0. Due to synergetic interaction of the components, the composition has high physiological activity and has not phytotoxic effect on crop plants. The invention enables to efficiently increase plant biomass in mixed legume-grass seeds by approximately 7.1-7.8% compared to inoculation of seeds with legume bacteria, and by 8.9-9.9% compared to inoculation of seeds with associative bacteria. The degree of inhibition of crop plants or damage falls 1.4-8-fold compared to control crop plants.
EFFECT: microbiological composition increases accumulation of green material by 87-91 centner per hectare or 20-23% compared to control plants - yield in mixed lupine seeds and barley without inoculation of seeds with microbiological preparations.
