When to plant Fonio in Arandis
Erongo, Namibia
Fonio (Digitaria exilis) — also called acha, hungry rice, findi or fundi — is West Africa's ancient small grain and the fastest cereal in the world: early types give grain in about 70 to 85 days, some in as little as 6 to 8 weeks.
| Fit | Favourable |
|---|---|
| When to plant | 29 Aug 2026 – 10 Feb 2027 open now |
| Expected harvest | about 1.4 t/ha |
| Harvest | From 28 Oct 2026 to 10 Jun 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 82–175 days per hectare, by hand |
Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Arandis is close to normal, so these dates match the pattern the area usually follows.
Planting after 10 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Arandis
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For fonio in Arandis, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The season in Arandis
| Rain in a typical year | About 25 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 25 mm falling roughly when it always does |

What fonio needs to grow here

What it takes to grow fonio in Arandis
| Nitrogen (N) | About 28 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 28 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 82–175 days per hectare, by hand |
These are the nutrients a fonio crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
