Growth and Yield of Maize (Zea mays L.) on an Acidic Coastal Plain Soil Fertilized with Compost and Inorganic Fertilizers

Our objective was to assess the effect of compost and other fertilizer types on the growth and yield of maize on a coastal plain soil. The experimental soil was an Ultisol inherently low in organic matter, clay and essential nutrients. We evaluated five treatments arranged into a randomized complete block design with three replications: no-fertilizer (control), NPK 15-15-15 (400 kg ha-1), organo-mineral fertilizer (3 t ha-1), compost (20 t ha-1) and liquid fertilizer (Ag-zime) at 5 litres ha-1. The results showed significant (p<0.05) differences among treatments with NPK 15-15-15 producing the tallest plants (181.96 cm) with the biggest stem girth (6.69 cm). Organo-mineral fertilizer had plants with the largest leaf area (784.07 cm2) and cob circumference (13.96 cm). Maize grain yields on plots with no-fertilizer (1.01 t ha-1) and liquid fertilizer (1.02 t ha-1) were significantly (p<0.05) lower than those in plots fertilized with NPK
