| Sumario: | Purpose – Nitrogen fertilization is a crucial factor in sustainable agriculture practices because it enhances the resilience of maize crops to climate change. This study aims to quantify location-specific adaptation measures to climate change using drought-tolerant maize varieties and N fertilization in the savannas of Nigeria using the Agricultural Production Systems Simulator (APSIM) model.
Design/methodology/approach – The calibrated APSIM-maize module was validated using an independent dataset from field experiments conducted under different N fertilization levels within savanna
agroecological zones (AEZs). The impacts of climate change were assessed under low and high emissions
representative concentration pathways (RCPs), 4.5 and 8.5 W m2 scenarios, for the near-term (2010–2039) and
mid-century (2040–2069). |
