An investigation on “effect of IBA, rooting media and polythene wrappers on air layering on guava cv. L-49” was undertaken at the Department of Fruit Science, KNK College of Horticulture, Mandsaur, RVSKVV, Gwalior (M.P.) during the year of 2015-16. The experiment was laid out in Randomized Block Design (RBD) with three replications. There were different concentration of IBA (2000 ppm, 4000 ppm and 6,000 ppm), rooting media (sphagnum moss and cocopeat) and different polythene wrappers (Black and White polythene) used as an air layering preparation in Guava. The results that maximum rooting (85.33%), number of primary (12.87) and secondary roots (33.33), length of primary (28.67 cm) and secondary roots (5.10 cm), diameter of primary roots (6.40 mm), fresh (4.20 g) and dry weight (0.90 g) of roots in layers prepared by application of IBA@ 6000 rolled in sphagnum moss and covered by Black Polythene. Growth of these layers was vigorous as depicted by new sprouts (9.67), number of leaves (47.00) and branches (8.00) per layered at 90 days after separation from mother plant. This was followed by layers treated with IBA@ 6000ppm + Sphagnum moss + White Polythene.
