The present investigation entitled “Effect of different potting media on survival and growth of air layered litchi cv. Dehradun” was carried out at the Advanced Centre for Horticulture Research, Udheywalla, SKUAST-Jammu during 2018-19. Different potting media (litchi orchard soil, sand, FYM, sawdust, vermicompost, rhizobacteria, cocopeat, perlite, neem cake and vermiculite) were used in combination with application of 500 ppm IBA. The results showed that among the different media, litchi orchard soil in combination with FYM and rhizobacteria was identified as best potting media for mass propagation of litchi in black polyethylene bags under open field conditions for obtaining highest survival percentage (93.51 %) and also gave better results with respect to all the parameters studied including increase in plant height (10.25 cm), shoot length (12.32 cm), shoot diameter (0.24 cm), length of longest shoot (16.62 cm), number of shoots per layer (6.20), fresh weight of shoot (46.49 g) and dry weight of shoot (28.29 g) after six months of planting. Similarly, the maximum per cent rooting (87.57 %), root length (9.05 cm), fresh weight of root (3.60 g), dry weight of root (1.29 g), partitioning coefficient of root (3.51 %), root: shoot ratio (0.05), maximum number of leaves/ layer (30.60), chlorophyll content of leaves (45.96 %), total leaf area (881.89 cm2), total dry weight of plant (36.26 g) and relative growth rate (1.48 mg/days) were observed in the media containing litchi orchard soil in combination with FYM and rhizobacteria. The maximum fresh weight, dry weight and partitioning coefficient of leaves (32.00 g, 7.06 g and 21.18 %, respectively) was obtained in media containing litchi orchard soil along with FYM and vermiculite. From the above studies, it can be concluded that the potting media containing litchi orchard soil along with FYM and rhizobacteria was found to be most suitable for survival and growth of air layered litchi cv. Dehradun.
