Abstract
A study to investigate the effects of organic and inorganic fertilizers on okra (Abelmoschus esculentus) (40 days local variety) was carried out at the biological garden of the University of Ilorin, Ilorin, Nigeria. Poultry manure was used as organic fertilizer while inorganic fertilizers consisted of single super phosphate, urea, and NPK 15:15:15. Results obtained revealed that application of poultry manure enhanced more vegetative growth, when compared with NPK 15:15:15, urea, single super phosphate and control experiment in terms of stem height, stem girth, leaf area, and number of leaves. Number of leaves was highest in plants treated with urea (10.3) compared with those treated with poultry dung (8.0), single super phosphate (3.0), NPK 15:15:15 (6.7) and least in the control experiment with (2.7). The study clearly indicated the efficacy of poultry dung as a promising organic manure while urea was the best among the inorganic fertilizers followed by NPK 15:15:15, and single super phosphate being the least for A. esculentus growth.
