The effect of different concentration of Indole Butyric Acid (IBA) on root initiation of apple cuttings. IBA was applied in five different concentrations (1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm and 5000 ppm) to study number of days to bud sprouting, number of shoots per cuttings, shoot length, number of leaves per cuttings, number of roots per cutting, root length and survival percentage. Significant results were obtained from all the parameters except number of leaves per cutting. Minimum days (15.00) to bud sprouting were recorded in cuttings treated with 3000 ppm, while maximum days were taken by untreated cuttings. Maximum number of shoots (3.00) and maximum shoot length (8.00 cm) were obtained from 3000 ppm, while same were minimum in case of Ti (control). Maximum number of roots (7.00) and maximum root length (11.25 cm) were observed in cuttings treated with 3000 ppm, while minimum number of roots (4.00) and minimum root length (7.00 cm) were observed in control. Best plant survival (76.67 %) was given with 3000 ppm concentration, while it was minimum (16.67 %) when the cuttings were not treated with IBA.
