Increasing inorganic fertilizer costs for food production and energy requirement for inorganic fertilizer production suggests the need to supplement the nutrient requirement of crops through organic amendments such as crop residues, manures and composts. Combined use of organic and inorganic fertilizers can improve rice productivity and sustain soil health and fertility. A pot experiment was conducted to compare the effects of N source as compost (organic), inorganic fertilizer (inorganic) or combined N source (organic + inorganic) on the nutrient uptake, growth and yield of NERICA 1 at the University of Ghana Agricultural Research Centre at Kade. Application of 100% N from compost induced higher tiller number, dry matter and grain yield compared to the no soil amendment (control) treatment. Among the N sources applied the combined application of organic and inorganic fertilizer exerted higher effects on dry matter, N uptake, tiller number, effective tiller number, plant height, chlorophyll content and grain yield than the application of inorganic N fertilizer alone or compost alone.
