Abstract: The study was done to determine the effect of different concentrations of Indole Butyric Acid (IBA) on air layering of Mango (Mangifera Indica). IBA @ 1000, 2000, 3000, 4000, 5000ppm and control (0.000ppm) were applied on two year old shoots of Dusehri , Sindhri, and Chowsa Mango varieties. The data were collected on number and length of roots. Maximum length of roots was recorded in shoots of Sindhri treated with 3000ppm concentration of IBA. Minimum length of roots was observed in shoots of Sindhri and Dusehri treated with 5000ppm concentration of IBA. There were no significant differences in number of roots among shoots treated with IBA concentrations of 2000, 3000, 4000ppm and control, which produced maximum length of roots. Shoots treated with IBA @ 5000ppm resulted in minimum length of roots.

Keywords: Air layering, Mangifera indica, mango, Indole Butyric acid, number and length of roots, varieties.
