Abstract
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 growing 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 while, the maximum partitioning coefficient of shoot (86.64 %) was observed under control. Similarly, the maximum per cent rooting (87.57 %), root length (9.05 cm), root diameter (0.04 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) and total dry weight of plant (36.26 g) 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. The maximum nutrient content of leaves N (1.46 %), P (0.24 %), K (2.16 %) and nutrient content of soil N (294.76 kg/ha), P (20.55 kg/ha), K (177.42 kg/ha) was observed in media containing litchi orchard soil in combination with FYM and rhizobacteria and maximum Na (25.27 ppm/ha) was observed in control. From the above studies, it can be concluded that the potting media containing litchi orchard soil alongwith FYM and rhizobacteria was found to be most suitable for survival and growth of air layered litchi cv. Dehradun.
