<![CDATA[The research was conducted in in Horticulture and Landscape Department fields - College of Agriculture - Tikrit University during 2023 Spring Season for Damascene Rose Rosa Damscena. The study included two factors; the first one is the growing media with three levels, mixture soil, vermicompost and soil mixture 1: 1, vermicompost and soil mixture 2: 1. The second factor was spraying nano-fertilizer with two concentrations: without spraying as control treatment, and spraying with nanotechnology with a concentration of 1 g l-1 ,the experiment consisted of 6 factorial treatments from the above factors interaction and carried out with full random complete block design R.C.B.D and by three replications. The results showed the superiority of mixture of vermicompost: soil 2: 1treatment in the characteristics of plant height and dry matter percentage which gave 96.54 cm and 15.72 % and recorded the highest rate of flowers number for the interaction treatment between mixture of vermicompost: soil 2: 1 and non-spraying with nano-fertilizer which reached 22.36 flowers.]]>
