Abstract: The evaluation of the application compost – mineral fertilizer on maize was carried out in two locations (Ujemen and Emaudo) of the Teaching and Research Farm, Ambrose Alli University, Ekpoma, Nigeria. The experiment was laid out in a Randomised Complete Block Design (RCBD) with seven treatments, replicated thrice. The treatments were: 2, 4, 6 and 8 t ha-1 of compost mineral fertilizer, 300 kg ha-1NPK 15: 15: 15, Urea (200 kg ha-1) and the control. Growth parameters such as plant height, stem girth and leaf area were measured at 4, 5 and 6 weeks after planting, dry matter yield (DMY) and grain weight were taken at harvest. Data collected were statistically analysed using Genstat statistical package. In both locations, compost-mineral fertilizer applied at the rate of 6 and 8 t ha-1 significantly (p
