A pot experiment was carried out at screen house, Faculty of Agriculture University of Maiduguri to compare the effect of NPK, bio-fertilizers and manures applications on growth and nutrient uptake by maize. The experiment consisted of 9 treatments of combined application of NPK at half and full recommended rates for maize, Azotobacter chroococcum, Bacillus megaterium and Pseudomonas fluorescence biofertilizers and cow dung and poultry manures and replicated three times in a Completely Randomized Design (CRD). Result of the treatment having half recommended dose of NPK, biofertilizers and poultry manure recorded the highest plant height at 3, 6 and 9 weeks after planting (95.19 cm, 148.63 cm, 149.63 cm, respectively) the highest total shoot and root fresh and dry weights (74.40 g, 196.93 g, 28.83 g, 46.93 g/plant, respectively). Higher nitrogen, phosphorus and potassium contents of the soil (2.76 g/kg N 0.13 mg/kg P2O5 and 1.41 Cmol/kg K2Osoil) were also recorded with the above treatments.
