October planting yields best results for climate‑resilient bambara groundnuts
Modeling shows that sowing bambara groundnuts in October produces the highest yields across southern Africa. Researchers used five decades of climate and soil records to run simulations for 49 growing seasons, covering thousands of altitude zones in South Africa, Lesotho and Eswatini while accounting for frost risk and omitting unsuitable lands. The legume supplies fiber, protein and essential minerals, and scientists stress that broader crop diversity is needed for climate resilience.
Key facts
- Simulations span 49 seasons using half‑century climate records.
- October sowing outperforms other months in projected yield.
- Study area includes 5,838 distinct altitude zones.
- Excluded land types: mines, commercial forests, cities, plantations, orchards.
- Crop provides notable amounts of protein and minerals.
