Rooting of Saraca asoca stem cuttings using three IBA (Indole 3-butyric acid) concentrations 300 ppm, 500 ppm and 1000 ppm IBA, have been carried out and the data obtained was evaluated with SVI (sprouting value index) method in order to interpret the vigor in rooting/sprouting and the suitable medium, which gives maximum results. Field studies were carried out using three rooting medium at a location in Central Kerala, Peninsular India, for three years at four months regular interval. The control cuttings do not recorded rooting. The results obtained indicate high SVI (sprouting value index), when prop root cuttings planted in root trainers with coir pith compost (RTCP) for all the three concentration of IBA applied. Sprouting percentage was increased and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment. Increased CWR and SUP percentages indicate defects in management practices, dormancy and or the genotype of the cultivar.
