This study was carried out to evaluate the effect of humic substance application on the growth of Anatolian larch (Pinus nigra
Arnold.) seedlings at the 5th growth stage. In the study,
characteristics such as seedling height, root collar diameter, seedling
fresh and dry weights, and vigor marker of larch seedlings treated with
humic substances were examined. For this reason, 5%, 10%, 15% and 20%
humic substance treatments were applied to the seedlings. Although there
were significant differences between treatments and seedlings, the
highest growth in terms of average seedling height (46,33 cm) and root
collar diameter (11,41 mm) was determined in the 5% humic substance
treatment. As a result of the correlation analysis, statistically
significant positive relationships were found among the seedling
characteristics. It was determined that humic substance treatments
positively affected the morphological characteristics of seedlings.
Furthermore, XRF analysis showed that humic substance application
increased the uptake of compounds such as K₂O, Cr2O3, TiO2, ZnO,
MnO and Nb₂O₅. Therefore, it was deemed appropriate to recommend the
application of 5% humic substance in the applications. The results of
the research support the widespread use of humic substance applications
in forestry applications.
