Abstract: During 2018, in the glasshouse of the Institute of Ornamental and Medicinal Plants - Sofia, а research was carried out to study the influence of fertilizers Masterblend, Kompovet and Kokovet on the growth and development of Scarlet sage (Salvia splendens). Root manuring of plants with organic fertilizers revealed a positive effect in the course of the phenophases. Flowering begаn with 4 to 6 days earlier. The duration of the flowering period compared to those of non-treated plants also increased with 4 to 6 days. When fertilized with Kompovet and Kokovet, plants had higher values of height and diameter than those of untreated plants. The best effect was achieved with Kokovet, where plants had better habitus - 29.4% higher and 19.0% larger.
