The aim of the study is to evaluate the effects of planting density and growth bed on growth and flowering of snapdragon. Different substrates including cocopeat+pearlit (40,60%), cocopeat+pearlit+vermicompost(20,60,20%),cocopeat+pearlit+vermicompost(10,60,30%), pearlit+ vermicompost(,60,40%), farm soil (100%), farm soil+ vermicompost (80,20%), farm soil+ vermicompost (70,30%) and farm soil+ vermicompost (60,40%) with density one and three plant in each pot were used. The experiment was carried out in completely randomized design. Each treatment was consisted of 1 or 3 plants and was replicated thrice. The data for parameters analyzed statistically showed significant effect of media combinations and density. Regarded parameters of growth and flowering such as flower length(cm), flower diameter (cm), root length (cm), stem length (cm), fresh weight (g) and longevity (day) exhibited the best media are the media that content 20%- 40 % vermicompost in compounding with soil (T: 7) or perlit except longevity that in medium content 20% vermicompost with 60% perlit showed the most amount.
