This study examined the effects of different container types and sizes on seedling emergence and growth of Plukenetia conophora Müll.Arg. (African walnut) to optimize nursery production practices. A 3 × 3 factorial experiment was conducted in a completely randomized design with three replications. The experiment was carried out at the greenhouse of the School of Agriculture and Agricultural Technology, Owerri. Seedling emergence, internode length, number of branches, number of leaves, and plant height were assessed at 9, 11, 13, 15, and 17 weeks after planting. The results revealed that container type, container size, and their interaction significantly (p < 0.05) affected seedling growth. Medium-sized plastic containers had the best growth performance, while polythene-based containers were less effective. These findings suggest that plastic containers of medium size can be used to achieve optimizing the nursery production of African walnut seedlings.
