In order to investigate the effect of organic fertilizers including compost and manure on morphological, yield and qualitative characteristics of Rosa damascena Mill, an experiment was conducted in a randomized complete block design with ۷ treatments in ۳ replications in ۲۰۱۸-۲۰۱۹ in Sirjan city. The treatments were compost (۲۰, ۲۵ and ۳۰ tons per hectare) and manure (۱۰, ۱۵ and ۲۰ tons per hectare) along with control (without fertilizer application). Results showed that fertilizer in all investigated characteristics was significant. Mean comparison of data showed that ۲۰ tons / hectare manure responded better regarding to canopy, height, leaf length and width, fresh and dry weight of flowers, number of flowers, phenol, chlorophyll, and antioxidant. As well, ۳۰ tons / ha compost  showed  maximum in number of branches, leaves per plant, fresh and dry weight per plant  and essential oil yield. Also, cluster analysis showed that ۲۰ and ۳۰ tons / hectare manure and compost were put in the same group. As conclusion, ۲۰ and ۳۰ tons / hectare manure and compost, respectively, had the maximum effect on morphological and qualitative characteristics of Rosa damascena Mill seedlings.
