Influence of Vermicompost Application on the Growth of Vinca rosea valiant, Pelargonium peltatum L. and Pegasus patio rose

Vermicompost (VC) is a nutrient-rich material that mixed with soil, and it used in this study. Four different environments were created such as control (Soil:VC:100–0%), mix one (Soil:VC:70–30% w/w), two (Soil:VC:50–50% three (Soil:VC:40:60% well-developed roses (Vinca rosea valiant, Pelargonium peltatum, Pegasus patio) seedlings transferred to individual pots. Plant growth parameters, i.e., the number of flowers, plant height, stem diameter, chlorophyll reading value, fresh flower weight, dry weight compared respect seedlings. The improvement height by 264, 71, 58, 255, 193% for Vinca valiant rosea, 138, 12, 160, 13, 55 112% P. patio rose, 50, 14, 23, 8, 61, 41% respectively, grown soil VC control. As result research, optimum parameter values Meter SPAD obtained from mix-three mediums all species. These results showed 40% 60% application could be proposed most effective medium ornamental production.
