Parkia biglobosa is an important Agroforestry species, providing many goods and services for sustainable development. In spite of that, its population is decreasing rapidly as a result of over exploitation. In order to promote the propagation of this species for sustainable production, this research investigated the influence of rooting media (top soil, sawdust and river sand) and two different hormones of varied concentrations (Indole-3-Butyric Acid and Indole Acetic Acid at 50, 100 and 150ml/1L concentrations) on the stem cuttings of the species. The data for the study were collected on percentage survival, number of roots, length of longest roots, total root length and number of leaves. Factorial experiment was used in a completely randomized design. The data were analysed with descriptive statistics and analysis of variance. Means were separated with Duncan Multiple Range Tests where there is significant difference (p<0.05). Cuttings that were treated with indole-3-acetic acid at 100ml/1L and planted in sawdust (SD/IAA/100ml/1L) produced highest results with 22.2% survival which was similar to 55.53% (SD/IAA/150), with longest (4.76 cm) length of longest root and total roots length (10.36 cm) formed and as such recommended for vegetative propagation of P. biglobosa.
