Fonio
Fonio is a small-grained West African cereal grown in parts of the region from Senegal toward the Lake Chad basin. It is valued as food, and its cultivation requires attention to weed competition, water management, harvest timing, and post-harvest grain handling.
Profile
- Species
- White fonio is Digitaria exilis.
- Region
- The crop is cultivated across parts of West Africa.
- Field establishment
- Prepare a suitable seedbed and establish the crop using appropriate local practice.
- Post-harvest
- Small grain size makes threshing and dehulling important processing steps.
Water & soil context
- Moisture (VWC)
- No volumetric water-content target is documented; follow rainfall and soil moisture through establishment and flowering.
- Salinity tolerance
- Salt sensitivity is not documented in the cited pages.
- Drought tolerance
- A drought class is not documented in the cited pages.
Illustrative monitoring-depth band
3–8 in
Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.
Provide moisture when needed for establishment and flowering, while recognizing that local rainfall patterns and field conditions determine irrigation decisions.
Problems to watch
- Weed early, monitor for bird damage near maturity, and harvest promptly to limit shattering losses.
Stress signs
- Lodging near maturity and damaged or missing grain from birds or shattering are visible crop losses; specific disease signs are not uniformly documented.
Where you'll find it
- Grain is consumed as a cereal food and processed after harvest by threshing and dehulling.
