The growth-regulatory activity of the complex algae extract from Spirogira sp. at pre-so wing treatment of soybean seeds was studied in green-house and field experiments. It was shown that phytoextract has stimulated seeds germination on 12%, plants growth on 11?37%, soybean productivity increased on 6?27% as well as activated the development and functional ability of rhizospheric nitrogen-fixing microorganisms. The quantity of oligoazotrophes increased in 1,5?6,3 times, nitrogenase activity in 1,5?1,7 times. The possibility aspects of growth-regulatory activity of the algae extract in both plants and rhizospheric microorganisms is under discussion. Our results have confirmed the perspectives of practical use of the biological activity substances from the algae at soybean growing in order to increase plants productivity and improve microbiological indexes of soil.
