Investigating N content of plants on chernozem soil, it was found that N fertilization
enhanced the N concentration in plant, but there was no relationship between N content
and biofertilizer rates at all (Table 4).

Similarly to chernozem, with increasing of N fertilizer rates the plant N concentration
increased, and this treatment effect was confirmed statistically (Table 5).
Relationship between biofertilizer rates and N content has been shown a very similar
trend like in case of dry matter content of parsley. At high rates of N, the biofertilization
gave an increase in N concentration of plant, while at lower doses just the opposite was
noticed.
