Abstract :Background and Aims A fertilizer combination containing five different fertilizers plus Osmocote was tested at different concentrations in the growing media of Rosa meilland Christof Columbus saplings. Morphological traits (e.g., leaf and flower biomass), physicochemical properties of the mixtures, leaf nutrient contents, and changes in moisture values (leaf and flower) were investigated. Methods Each mixture included 12 saplings with three replicates (total: 144 saplings). Weekly measurements were taken for 16 weeks to determine leaf length and diameter, number and length of shoots, flower diameter and number, and sapling diameter. Physical properties (sand, silt, clay) and macro- and micronutrient contents of the growing media were analyzed. One-way ANOVA was used to compare treatments. Results Although some weekly morphological measurements differed significantly, no consistent trend was observed. In cumulative comparisons (16 weeks), only flower diameter differed significantly among mixtures, while leaf nutrients and both flower and leaf biomass did not. Among physicochemical properties, water saturation, Nt, P2O5, K2O, Cu, Fe, Mn, and Zn differed significantly between mixtures. Leaf moisture values also showed significant differences. Conclusion Overall, the lowest values were generally found in mixture 4 (80% peat, 10% river sediment + 10% pumice stone + fertilizer), which used only the fertilizer combination.
