The research was conducted to evaluate effect of different concentrations of IBA on rooting of guava in Fruit Crop Research Program, Horticultural Research Institute (HRI), NARC Islamabad. Semi hard wood cuttings, 5-6’’ in length having 2 to 3 buds, of guava cultivar was taken from about 1 to 1/2 year old uniform guava branches. These cuttings were treated with IBA 4000, 3000, 2000 and 1000 ppm while untreated cuttings were used as control. The greenhouse was equipped with heater and air cooler keeping the temperature at 240C and relative humidity was maintained at 60-70 % during the experiment period. Cuttings were irrigated through mist and the cuttings were planted in experimental pots containing sandy soil. The data was recorded for rooting percentage, number of roots per cuttings, root length per cutting and survival percentage. It was concluded that the cuttings treated with IBA 2000 ppm produced maximum number of roots. While in survival the IBA 2000 ppm is at the top. In all treatment very small difference exist without control treatment in which variation were exist, while in IBA the difference between different parameter were existed.
