Abstract: The present investigation entitled “Standardization of different potting media on vegetative growth and flowering of Dendrobium orchid cv. sonia 17 under shade net conditions in high altitude tribal zone of Andhra Pradesh†was carried out at Horticulture Research station, Chintapalli, Visakhapatnam district of Andhra Pradesh during two consecutive years of 2016-17 and 2017-18. The experiment was laid out in a completely randomized design with 10 treatments and each treatment replicated thrice. The data recorded on various parameters viz., vegetative growth, flowering and were statistically analyzed. Significant differences were observed among different potting media on various vegetative growth parameters in Dendrobium orchid cv. Sonia 17. Among all the treatments, Coconut husk chips + Brickpieces + Charcoal + Gravel (2:1:1:1) showed significantly the best results with all the vegetative growth parameters viz., plant height (29.66 cm), number of leaves per plant (11.75), number of shoots per plant (9.04), shoot girth (3.63 cm), leaf length (11.96 cm) and leaf breadth (3.48 cm). Significant differences were observed among different potting media on various flowering parameters in Dendrobium orchids cv. Sonia 17. Among all the treatments, Coconut husk chips + Brickpieces + Charcoal + Gravel (2:1:1:1) showed significantly the best results with respect to days taken to spike emergence (152.95 days), days taken to spike development (26.48 days), spike length (46.40 cm), spike girth (1.74 cm), spike weight (17.33 g), number of flowers per spike (8.06), flower diameter (6.43 cm), number of spikes per plant (3.58).
