Standardization of growing medium for anthurium cv. Flame under protected conditions

the present experiment was conducted to standardize of growing medium in pots for anthurium (Anthurium andreanum L.) cv. Flame under protected conditions of 75 per cent shade net house. Combinations of growing medium significantly influenced the vegetative growth, flowering pattern and flower production of anthurium. The over all best performance was recorded in medium comprised of saw dust + brick pieces + wooden charcoal + soil + sand + FyM (2:1:1: 1: 1:1), i.e. t₇ treatment for almost all the parameters like leaf area (229.11 cm²), petiole length (21.31 cm), minimum days to flowering (260.47), stalk length (36.16 cm), spathe length and width (8.5 and 8.08 cm, respectively) and number of flowers per plant (6.07). The maximum number of leaves per plant (7.40), highest number of suckers per plant (5.00) and longest inflorescence longevity (63.53 days) were recorded in treatment combination involving saw dust + wooden charcoal + soil + sand + FyM (2:1:1: 1: 1), i.e. t₆ treatment. the growing medium consisting soil: sand: FyM (t₁) showed the least response for all the parameters.
