Abstract: | The inoculation of mycorrhizal maize plants with three isolates of microaerophilic diazotrophic bacteria obtained from the
mycelium of arbuscular mycorrhizal fungi associated with three grasses (Arrhenatherum elatius - bacterial isolate ARR, Agropyrum
repens - isolate AGR and Poa annua - isolate POA) caused no increase in nitrogen content in plant biomass. The inoculation
with bacterial isolate ARR resulted in the decreased plant growth. Bacterial isolate AGR decreased the percentage of the root
length colonized by arbuscular mycorrhizal fungus Glomus fistulosum. The inoculation with both mycorrhizal fungus and isolate
POA increased significantly the concentration of phosphorus in plant shoots compared to uninoculated control.
