Abstract: The fertilizer management practices have not ensure the desired improvement in yield for okra (Abelmoschusesculentus L. Moench) due to differences in fertilizer types. The search continues for nutrient sources that would provide adequate nutrition for the crop on the season. A pot experiment was carried out at the Teaching and Research Farm, Ekiti State University, Ado Ekiti, Nigeria to evaluate the growth and fruit yield responses of okra (Abelmoschusesculentus L. Moench) to the application of air-dried milled moringa leaf (MML), poultry manure (PM) and NPK fertilizer. The MML was applied at 400, 800, and 1200 kg/ha; NPK 15-15-15 at 250 kg/ha and PM at 10 t/ha separately and in all possible combinations in completely randomized design in three replicates. The parameters measured were plant height, stem girth, number of leaves, leaf area, number of fruits and fruit weight. The single treatments differed significantly (P = 0.05) with the combinations of the treatments giving better performance. The 800 kg/ha MML + PM treatment gave the tallest plants (103.33 cm) and followed by single application of PM (102.33 cm). The application of 400 kg/ha MML + PM + NPK produced the highest number of fruits but 800 kg/ha MML + PM + NPK gave the highest fresh fruit (42.70 g) and dry fruit (20.50 g) weight. 800 kg/ha gave best growth performance among MML but 1200 kg/ha gave best yield. This suggests that MML can be used as source of nutrients to grow okra.
