Abstract: Raising good quality planting material at nursery stage is a very important aspect for success of any orchard. Intensive applied research is needed for standardization of nursery techniques in respect of optimization of rooting media for quality planting material production. Layering is a method of vegetative propagation in which a branch is induced to grow roots before it is separated from the parent plant. Moreover, the success of layers is governed by various factors viz, Availability of moisture, quality of rooting media, position of branches, season and wrapping material polythene sheet. The objective of this study was to determine the effect of different rooting media viz., Sphagnum moss, Vermicompost, Vermicompost + VAM, Vermicompost + Azotobacter, Vermicompost + VAM + Azotobacter and wrapping material (White transparent polythene, Black polythene and Aluminium foil) air-layers in litchi. Among these different rooting media Vermicompost + VAM + Azotobacter treated air layers produced maximum rooting percentage (86.88), maximum number of primary (20.66) and secondary roots (18.96), Maximum length (8.13 cm) of primary and secondary roots (11.06 cm) and minimum thickness of primary roots at tip (0.74 mm) and base (0.44 mm). The same rooting media produced highest fresh and dry weight of roots and shoots. Among the different wrapping material, White polythene found as an effective for most of the rooting characters and survival percentage.
