The present investigation was undertaken to study the effect of different concentrations of Indole 3-butyric acid (0, 2000, 4000, 8000 and 10000 ppm), different types of rooting media (i.e. sphagnum moss, coco peat, ver-micompost, sphagnum moss + coco peat and sphagnum moss + coco peat + vermicompost) and the interaction of these in different combinations on rooting and growth characteristic of guava, cv. L-49. The results revealed that the exogenous application of Indole 3-butyric acid (IBA) 8000 ppm with media combination of sphagnum moss + coco peat + vermicompost (I3M5) significantly increased the root characters i.e. success percent of air-layers (83.3 %), callus formation (23.7), number of primary roots (24.21) and secondary roots (32.57); and growth characters i.e. number of leaves (48.17), branches (7.92) and sprouts (8.48) and survival percentages (83.18) over the other treat-ments and control. Among the rooting media, the combination of sphagnum moss + coco peat + vermicompost (M5) produced the highest rooting percentage (71.27), root characters and growth characters during months of July and August.
