Opis (eng)

Microbiological biofertilizers are gaining more and more attention in the global market as an environmentally healthier substitute for conventional chemical fertilizers. This paper investigated the effect of treatment of two-year-old northern red oak seedlings with commercial biofertilizer Slavol® during one growing season. The medium was prepared according to the producer’s instructions and applied foliar in late June. Seedling height and root collar diameter were measured as the prominent representatives of seedling quality growth parameters. The results confirmed the positive impact of the biofertilizer on seedling growth. Mann-Whitney U test showed a statistically significant difference in seedlings height (U = 42.000; p < 0.001) and root collar diameter (U = 56.000; p < 0.001) among the treated seedlings group at the beginning and the end of the experiment. In the control group, the statistically significant difference was noted for seedling root collar diameter (U = 55.000; p ˂ 0.001), but not for seedling height (U = 163.000; p = 0.624) at the experiment beginning and end. The results indicate that Slavol® biofertilizer influenced two-year-old northern red oak seedling height enhancement at the end of the experiment, but not on seedling root collar diameter, which had significant growth in both control and treated plants.
