Dacryodes edulis (G Don) is an evergreen tree attaining a height of 18-40 m in the forest but not exceeding 12 m in plantations. In Nigeria, it is an important food supplement. The species is a delicacy among the people in several parts of Nigeria where it is consumed in association with other foods such as fresh maize. It is a highly nutritious fruit. Lack of knowledge, especially in propagation techniques for this woody species, inhibits farmers in Africa, including Nigeria, from successfully growing this multipurpose forest fruit tree species. A study was conducted to determine the germination and seedling growth of Dacryodes edulis (African pear) as affected by different planting media: top garden soil, river sand, sawdust and a mixture of river sand and sawdust. Sawdust and river sand was mixed in a ratio of 50:50 in the Forestry Nursery of Federal University of Agriculture Makurdi. Seeds were procured and sown in the poly pots filled with various sowing media of sawdust river sand, top soil, and composite mixture of sawdust and river sand. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replicates. The results showed seeds planted in River sand had the highest germination of 100% and was significantly different (p=0.05) from those sown in other growth media (river sand and river sand combined with sawdust had 96.67% each while topsoil had 80%). The results also indicated that the performance of the seedlings in terms of height, number of leaves, leaf area and collar diameter planted in the composite mixture of Sawdust and River was better though not significantly different (p >0.05) compared to those in the other growth media except for Top soil medium that had relatively low performance. This study has established that the germination and seedling growth of D. edulis are significantly affected by planting media; while river sand recorded better growth performance and is therefore recommended for raising seedlings for plantation establishment.
