Aim - to identify the peculiarities of useful soil microorganisms on growth, development and yield of onion. Methods of research - microbiological, biochemical, vegetation , field . Strains used diazotrofiv ground belonging to the genera Rhizobium, Azotobacter, Azospirillum and Enterobacter. Nitrogen fixation activity was determined by acetylene. Field experiments were conducted on sod-podzolic soil and chernozem lehkosuhlynkovomu default. The most important results of the research: the effects of diazotrofs on germination, speed and friendliness of onion seed germination in the laboratory and selected strains of microorganisms that have the greatest effect on the studied parameters , the influence of inoculation on the yield and quality of onion and the analysis of the obtained data field and laboratory studies. Shown that inoculation of onion seeds engineered microbial agents observed the highest compared to other options potential activity of nitrogen fixation in the rhizosphera and bulk dry matter of plants, and as a result, received the highest yield of onion. Increase in yield when using biopreparation ABT (modified ) from A. vinelandii M -X was for onion varieties Stryhunivska Nosivska 23% for grade Veselka - 26 % (in conditions of Polessye ) grade Tkachenkivska - 26 % grade Veselka - 20% (under steppes). The use of scientific developments - the results on the peculiarities of microbial agents on onion plants can be used in agriculture as an element of its breeding technologies that will improve the productivity of this crop and quality of received products.
