In this study, the effect of a living bacteria (Bacillus megaterium var. phosphaticum, Azotobacter chroococcum) containing biofertilizer, made in Hungary, was investigated on the germination and dry matter production of maize seedlings in germination tests. The biofertilizer was applied in concentrations of 1 ml·L⁻¹ and 3.5 ml·L⁻¹. Seed and filter paper treatments were used in the experiments, completed with autoclaved biofertilizer treatment. Germination and weight of shoots and roots were evaluated. It was observed that the seed-and-filter paper treatments with biofertilizer significantly increased – by more than 20% – the numbers of the germinated seeds in comparison to the untreated control. The dry weight of the shoot and root was higher by more than 7% than the control in the case of treatments with biofertilizer. Based on this result, it was concluded that there is a positive effect of PGPB on germination, as well as it is supposed, that the applied biofertilizer treatments stimulated the germination and growth of maize by reason of excreting phytohormones and enhancing the nutrient mobilization from the seed.
