Low inherent nitrogen (N), phosphorus (P), and potassium (K) contents of smallholder farms limit maize grain yield. Maize grain yield response to N, P, and K mineral fertilizer application and economically optimal rates for nitrogen (EOR<sup>N</sup>), phosphorus (EOR<sup>P</sup>), and potassium (EOR<sup>K</sup>) were evaluated on a Ferric Acrisol within the semi-deciduous forest zone of Ghana. The nutrient rates evaluated were N (0, 30, 60, 90, and 120 kg N ha<sup>-1</sup>), P (0, 30, 60, and 90 ...[more]
