Annona muricata Linn is one of the highly valued medicinal plants. Present study was subjected to six media viz: Top soil + sawdust, river sand + top soil, river sand + sawdust, sawdust only, top soil only and river sand only (control). Percentage germination (%), plant height (cm), number of leaves per plant, stem girth (cm) and leaf area (cm2) were determined for three months. The results revealed that the highest mean germination of 80% was recorded in seeds sown in river sand + sawdust medium. While seeds sown in river sand + top soil and those sown on top soil only gave the same percentage of 40% which were the least percentage germination recorded. The results of this study also showed that seedlings planted on top soil only has the highest mean height of 19.12cm, leaf production of 11.33, stem girth of 1.50cm and leaf area of 31.20cm². This was followed by the seedlings planted on river sand + top soil medium with mean height, number of leaves, stem girth and leaf area of 17.78cm, 10.83, 1.32cm and 17.81cm² respectively. While the least seedling development was recorded in seedlings planted on river sand only which gave mean plant height, leaves production, stem girth and leaf area of 6.42cm, 3.67, 0.52cm and 9.8cm² respectively at three months after planting. It is therefore opined that river sand +sawdust was the most effective growth medium for enhancing best seed germination while top soil only was the most effective growth medium for enhancing best seedling development in Annona muricata Linn.
