Application of biologically fixed nitrogen is a problem of high priority in modern agriculture production. The aim of this research was to investigate the influence of bacterization on the number of several systematic and physiological groups of microorganisms in rhizospheric soil as well as the length of the above ground parts of maize plant. The experiment was carried out on NSSC-640 maize hybrid, which seeds were inoculated with fluent inoculum just before sowing. The effect of inoculation depended on the level of mineral fertilization and the species and the strain of microorganisms. Maize seed bacterization led to the increase of the number of free nitrogen-fixing organisms, phosphorus mineralizing and phosphorus solubilizing organisms. The number of azotobacter, ammonifiers, fungi and actinomycetes was decreased. The bacterized plants were in relation to the control plants, better developed and bigger in size. Application of microbial fertilizers, the need for mineral fertilizers could be reduced.
