Optimizing Nitrogen Fertilization Regimes for Sustainable Maize (Zea mays L.) Production on the Volcanic Soils of Buea Cameroon

Impact of nitrogen fertilizer rates (control–0, 50, 100, 150, and 200 kg ha−1) on maize grain yield (Mean ± SD). Values across N fertilizer rates with different letters are significantly different (P &lt; 0.05).
