This experiment was conducted at Federal College of Forestry demonstration farm Jos, to determine the influence of Poultry Manure and NPK fertilizer on growth and yield of Abelmoschus esculentus L. during the 2018 growing season. A randomized complete block design (RCBD) with four treatments that were replicated three times was used. Characters assessed are germination percentage, plant height, number of leaves, number of branches, days to 50% flowering, number of fruit per plant, fruit length, fruit diameter, fresh fruit per plant weight and yield of okra. Results obtained indicate significant differences of growth and yield of Abelmoschus esculentus L between the treatments. Combine application of poultry manure produces the highest germination percentage (82.0%), plant height (53.2cm), number of leaves (27.3), number of branches (17), days to 50% flowering (41.5), number of fruit per plant (65.8), fruit length (13.4cm), fruit diameter (3.3cm), fresh fruit per plant weight (10.7g) and yield (3.3 tons/ha). It could be deduced from the findings of the experiment, that combine application of poultry manure and NPK fertilizer may be recommended to the farmers of Abelmoschus esculentus L. for better yield in the study area.
