Scientists have developed a model to advise farmers in Southern Africa on the optimal time to plant bambara groundnuts, a native crop. By analyzing 50 years of climate and soil data, researchers simulated 49 growing seasons.
The study’s findings indicate that planting in October, coinciding with the region’s rainy season, leads to the highest yields. Later sowing dates risk frost damage and reduced harvests. Southern Africa’s reliance on rain-fed maize, wheat, and rice is challenged by water stress and climate change, impacting food security.
Indigenous crops like bambara groundnuts are often more resilient to drought and can thrive in low-fertility soils. These crops are also nutrient-rich, providing fiber, protein, and essential minerals. The researchers emphasize the importance of diversifying crops for climate resilience and note that farmers need guidance on planting times for these underutilized plants.
