Abstract
The paper presents the study of active nitrogen fixation bacteria of genera Azotobacter, Azospirillum, Bacillus, Flavobacterium, Enterobacter and Pseudomonas isolated from root zone of spring wheat plants. The ability of selected diazotrophs to form associative systems with spring wheat was investigated. The most significant increase of molecular nitrogen fixation activity in root zone of plants was observed under the Azospirillum species background.

Summary
The paper presents the study of active nitrogen fixation bacteria of genera Azotobacter, Azospirillum, Bacillus, Flavobacterium, Enterobacter and Pseudomonas isolated from root zone of spring wheat plants. The ability of selected diazotrophs to form associative systems with spring wheat was investigated. In the 70s of the last century the phenomenon of increased nitrogen fixation activity in the root zone of plants, called associative nitrogen fixation was discovered. Studies in this area began with the works of J. The aim of this study was to investigate the microbial nitrogen fixation communities of root zone of spring wheat plants and to obtain the culture of diazotrophs that can form active associations with plants
