Background: Poor soil fertility management in Ghana has necessitated the need to investigate the appropriate source of nitrogen which enhances nitrogen use efficiency and improves maize productivity under rainfed condition. Methods: The experiment consisted of five treatments; control (no fertilizer), NPK 15-15-15 (90 kg N ha-1), urea (90 kg N ha-1), poultry manure (4.2 tons ha-1) and combination of NPK 15-15-15 and poultry manure (½NPK 15-15-15 + ½ poultry manure). Randomized complete block design was the experimental design used for the experiment with three replications. Result: The greatest grain yield (5,551 kg ha-1) and biomass yield (14,296 kg ha-1) for the major rainy season were recorded by the combined application of NPK 15-15-15 and Poultry manure treatment, while the highest grain yield (3,507 kg ha-1) and biomass yield (7,976 kg ha-1) was recorded by NPK 15-15-15 treatment during the minor rainy season.
