Abstract:
The present investigation entitled “Effect of different growing media on growth and flower yield of calendula (Calendula officinalis L.)” was carried out during the year 2021-22 in Rabi season at Department of Floriculture and Landscape Architecture, Pt. KLS College of Horticulture and Research Station, Rajnandgaon (C.G.). The growing media were used T₁ Soil (Control), T₂ Soil + Vermicompost, T₃ Soil + F.Y.M., T₄ Soil + Cocopeat, T₅ Soil + Leaf mould, T₆ Soil +Rice husk, T₇ Soil + Vermicompost + Cocopeat, T₈ Soil + Vermicompost + Leaf mould, T₉ Soil + Vermicompost + Rice husk, T₁₀ Soil + F.Y.M. + Cocopeat, T₁₁ Soil + F.Y.M. + Leaf mould, T₁₂ Soil + F.Y.M. +Rice husk. The experimental results revealed that minimum number of days taken for first bud emergence (26.20 days), minimum days to opening of flower from bud emergence (9.27 days), maximum flower longevity (7.40 days), maximum fresh weight of flower (12.90 gm) and maximum diameter of fully opened flower (6.51 cm) was recorded under the treatment containing Soil + Vermicompost + Leaf mould (T₈).
