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

Maize nitrogen use efficiency (kg kg−1 ± SD) assessed by the Nitrogen-Partial Factor Productivity (N-PFP) across nitrogen fertilizer rates (50, 100, 150, and 200 kg ha−1). Values across N fertilizer rates with different letters are significantly different (P &lt; 0.05).
