Abstract
The relevance of the study is conditioned by the need to develop more environmentally friendly farming methods with a simultaneous increase in crop productivity. Thus, the purpose of the study was to screen microorganisms for their positive effect on the germination of wheat seeds with the further formation of consortia to achieve the most favourable effect on plant growth. To form a consortium of microorganisms, screening of microorganisms isolated from the rhizosphere of wheat soil was carried out. At the second stage, the influence of culture liquids of isolates and collection strains of microorganisms on wheat growth rates was studied, based on which consortia of microorganisms were formed to achieve an additive effect. As a result, microorganisms with the most significant effect on wheat growth indicators were selected from 35 collection strains and 16 isolates, of which 3 consortia were formed. A study of the impact on wheat growth activity was conducted for consortia and, according to the results, consortia No. 1 and No. 2 were selected as the most actively influencing growth indicators. The need to develop sustainable farming is a current trend in the development of agriculture. The use of biological products based on microorganisms is a safer way to increase crop productivity. Therefore, one of the important tools is the screening of the most effective and favourable microorganisms for the further formation of consortia. In this study, work was carried out on screening of soil microorganisms, as a result of which 3 consortia were formed and investigated, 2 of which showed a significant positive effect on the growth activity of wheat plants. Thus, the results obtained can be used in agriculture as an alternative to conventional fertilisers and an extension of "green" agriculture.
