Abstract: This research was carried out to study the effect of organic fertilizer produced at different proportions by mass using same substrate made up of Neem seeds, rice husk, blood meal, bone meal, calcium carbonate in five different formulations on the growth and development of maize crop (zea mays). The constituents were prepared by mixing and blending using mixer and hammer mill respectively. Physicochemical analysis was carried out to determine the nutritive value of the formulated organic fertilizer for the presence of Nitrogen, Phosphorus and Potassium (N. P. K). The fertilizer was subjected to a pot experiment, using a complete randomized design method, in which each soil was treated with the prepared organic fertilizer formulation at high and low amount of application and planted for a period of 12 weeks. The result of physicochemical analysis of the various proportion of organic fertilizer indicated that formulation type 5 presented the highest percentage of nitrogen content (i.e. 14840 mg/kg). This was due to the increase in proportion of Poultry litters in the formulation type 5. Moreover, the formulation type 3 recorded the lowest percentage of nitrogen (i.e. 4060mg/kg). There was no significant difference (P< 0.05) in the vegetative growth of maize for various treatments. However, formulation type 5 at high amount of application gave higher values of plant height, stem girth, leaf area and number of leaves than other formulations. This implies that organic fertilizer could be potentially promising option to chemical fertilizer as a soil conditioner and a good source for plant nutrients.
