Ten wheat cultivars were inoculated with 19 different Azotobacter strains. Plants were grown in Petri dishes on wet filter paper and watered with full nutrient solution. It was established that number, length and dry matter mass of primary roots, the length of the aboveground part, concentration and content of nitrogen in the plant tissue varied depending on the relationship between the investigated wheat varieties and applied Azotobacter strains. Rhizogenesis of some varieties was stimulated by a specific Azotobacter strain. The length of the aboveground part was significantly increased with all varieties under the influence of inoculation, whereas, dry matter mass of some varieties was above, below or at the control level. Nitrogen concentration in teh aboveground part was with most varieties, higher with inoculation and with 2 varieties at the control level. With inoculation the nitrogen content in the aboveground part was, in the majority of cases, higher and in the root lower as compared with the control.
