The reaction of soybean (Glycine max (L.) Merr.) on inoculation with algal-rhizobial compositions based on Bradyrhizobium japonicum nodule bacteria and Nostoc punctiforme cyanobacteria was studied. It was shown that soybean seed inoculation with algal-rhizobial compositions promotes germination ability and influences positively on germ forming. Inclusion of cyanobacteria into inoculation suspension of rhizobia and their Tn5-mutants in some combination is able to stimulate soybean growth and development, accumulation of photosynthetic pigments in leaves and increase protein content in the seeds. However the algal-rhizobial compositions have no essential effect on nitrogen-fixing activity and plant productivity as well. The obtained data show that it needs to seek the efficient algal-rhizobial compositions for soybean inoculation by optimal selection of bacteria strains and corellation of inoculation agents. The algal-rhizobial compositions based on microorganisms with genetic modified properties are required for further investigation.

Key words: legume-rhizobial symbiosis, algalrhizobial compositions.
