Scientists predict planting times for native African nuts
Researchers finished a new study to help farmers in Southern Africa know the best time to plant native bambara groundnuts.
Experts analyzed fifty years of weather and dirt records to model forty nine growing seasons for the specific crop. Their model found that planting in October produced the highest yields while avoiding frost damage later in the year.
Much of the region still relies on rain fed maize but water stress makes production difficult under changing climate conditions. Indigenous plants are often more drought resistant and can thrive in low fertility soils where other staples fail.
The team used the Food and Agriculture Organization AquaCrop model to simulate conditions across five thousand eight hundred thirty eight altitude zones. They accounted for daily rainfall and air temperature to create more accurate suitability maps for the legume.
The research excluded unsuitable land uses like mining areas and urban zones to prevent over estimation of suitable production regions. This approach stops smallholders from gambling their livelihoods on inaccurate maps based on long term climate averages alone.
