Nitrogen Dynamics under Cowpea–Pigeon Pea Intercropping and Residue Management in Malawi’s Drought Prone Areas
Soil nitrogen depletion remains a critical barrier to sustainable crop production in Malawi’s drought-prone smallholder farming systems. This study investigated the influence of cowpea– pigeon pea intercropping and residue management on soil nitrogen dynamics. Result show strengthened nitrogen cycling through biological nitrogen fixation, improved residue quality, and increased residue biomass. This integrated approach provides a climate-smart pathway to restore soil fertility and enhance the resilience and productivity of smallholder farming systems in Malawi’s drought-affected regions.
