Abstract: Cuttings with 15 cm length taken from one year old healthy shoots were used to study the influence of the auxin Indole-3-butyric acid on rooting in curryleaf. Based on the maturity condition, cuttings were classified into hardwood, semi-hardwood and softwood. In softwood cuttings, a pair of leaves were retained. IBA at 500, 1000, 1500 and 2000 ppm were prepared in 0.1 N Potassium hydroxide solvent. In every treatment 50 cuttings were used. 2 cm basal portion of the cuttings were treated by quick dip for 15 seconds and planted in mist chamber. Highest percentage of rooting was observed in hardwood cuttings treated with 2000 ppm IBA and rooting percentage decreased with reduction in the concentration of IBA. Plants obtained from IBA 2000 ppm treatment had the best survival (91.67 ).
