Abstract

An experiment was conducted to evaluate the combined effect of amended media and vermiwash on growth and flowering of landscape gerbera grown under greenhouse condition. CPV and Soil amended with vermicompost, hydrogel and HBM had significant positive effects on growth and flowering of gerbera. Appearance of first true leaf in newly transplanted plants (3.67 d), number of leaves per plant at first flower appearance (16.33), appearance of first true leaf after harvest (4.00 days), leaf area per leaf (82.80 cm2), maximum number of primary roots (42.00), minimum days taken for appearance of first flower bud (49.67), minimum days taken for first flower harvest (71.67), flower head diameter (10.11 cm), days taken to flower senescence in plants (20.33), fresh and dry weight of plant was recorded on CPV+PHG+VC with 20% vermiwash sprayed. Compared to all other treatments chlorophyll content and relative water content significantly higher with vermicompost 20%, PHG 0.25% and HMB 1.0% with vermiwash 20% sprayed. The beneficial effects of amended media were associated with change in physical and chemical properties and hormone like effect of vermiwash which increase the growth of the plants. Therefore, it can be concluded that, plant performance was best in the media containing CPV+PHG+VC with 20% vermiwash concentration.
