The simple air layering recorded significantly minimum days to root appearance (22.97 days), maximum success percentage (80.95%), maximum numbers of primary (23.14) and secondary roots (42.10), maximum length of primary (5.40 cm) and secondary roots (3.56 cm), maximum diameter of primary (1.72 mm) and secondary roots (0.54 mm), maximum fresh (0.94 g.) and dry weight of roots (0.53 g.). With respect to rooting media, sphagnum moss recorded significantly lowest days to root appearance (20.99 days), highest numbers of primary (29.83) and secondary roots (48.62), highest success percentage (58.83%), highest length of primary (6.08 cm) and secondary roots (4.03 cm), highest diameter of primary (1.84 cm) and secondary roots (0.60 mm), highest fresh (1.00 g.) and dry weight of roots (0.60 g.) Among the different biological agents, bio-mix recorded minimum days to root appearance (22.05 days), maximum success percentage (54.91%), maximum numbers of primary (23.80) and secondary (42.82) roots, maximum length of primary (5.55 cm) and secondary roots (3.68 cm), maximum diameter of primary (1.74 mm) and secondary roots (0.55 mm), maximum fresh (0.95g.) and dry weight of roots (0.54 g).

The treatment combination of L1M1B1(Simple air layering + Sphagnum moss + Bio-mix) was recorded significantly minimum days to root appearance(19.08 days), maximum success percentage (97.50%), maximum numbers of primary (31.65)and secondary roots (51.03), maximum length of primary (6.35 cm) and secondary roots (4.20 cm), maximum diameter of primary (1.87 mm) and secondary roots (0.62 mm), maximum fresh (1.03 g.) and dry weight of roots (0.63 g).
