An experiment was carried out during rabi season in 2020-2021 at Department of Plant Physiology, AB & MAP, COA, IGKV, Raipur (C.G.) under shade net house. The experiment was laid out in completely randomized design (CRD) with four treatments, each treatment replicated thrice. The effect of four different media i.e., cow dung and vermicompost, charcoal, tree barks and pieces of bricks was studied. It was observed that treatment of tree barks was found superior to improve in height of pseudobulb (19.20 cm), number of internodes per plant (3.80), internode length (4.60 cm), number of leaves (5.26), shoot girth (4.16 cm). The treatment pieces of bricks recorded best for root length (17.16 cm). The treatment cow dung + vermicompost recorded best for leaf area (44.68), light intensity (153.90), chlorophyll value (46.70).
