Abstract The wild yam, Discorea Villosa, alata and bulbifera tubers used for this study, was obtained from the farm in Rufus Giwa Polytechnic, Owo, Ondo State. The samples were prepared by cleaning, washing, peeling and cutting into smaller sizes, dried for one month. The sample were powdered in Willey milled at 60 mesh size and stored in screw cap bottle at room temperature for further analysis. The samples were evaluated for its nutritional quality, from the present investigation, it is observed that most of the yams were found to be a good source of protein but that of villosa (7.44±0.04) is higher than that of alata (5.15±0.10) and bulbifera (4.88±0.14). Lipids were significantly low in villosa (0.04±0.02) than the rest, alata (5.28±0.18) and bulbifera (6.14±0.11). Crude fibre, moisture contents of the three samples had no significant difference while carloric value of villosa in terms of carbohydrates was higher (81.12±2.98) than the rest. No significant difference in vitamin contents while potassium was higher in villosa (24.30±1.78) than alata (7.86±0.14) and bulbifera (15.54±0.30) in terms of minerals composition. These tubers which have great potentials to serve as a source of very necessary nutrients can be used as food for humans and animals
