Aim of this work is to determine the applicability of growth stimulators in intensive cultivation of spruce seedlings and to assess their effect on the seedlings based on different varieties of applied fertilizers. Hypothetically, every examined variety (excluding the control variety) would respond with increased growth in both aboveground and belowground biomass. Theoretical part of presented thesis is based on knowledge of scientific literature. Practical part describes the methodology of measurement and data processing. On the provided plot we established eight varieties, which were compared to ecach other (Silvamix®R30S2+VERMAKTIV Stimul, Silvamix®R30S2, Silvamix®R30S, Silvamix®R50S2, Silvamix®R30, Agluform®90S, calcareous dolomite, control). Data were collected in course of two years. Observed parameters were namely: aboveground height, yearly increment, thickness of root collar and overall health and vitality. Results are matching the criteria in majority of observed cases, best results were detected in R50s2, SR, SRs2_VrmS varieties, worst resutlts were obtained in VapDol together with K variety. Measured data were analysed with STATISTICA software using the ANOVA variance analysis.
