When to plant Fonio in Dujis
Garissa, Kenya
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 | 11 Apr 2027 – 9 Aug 2027 opens in 27 weeks |
| Expected harvest | about 1.5 t/ha |
| Harvest | From 10 Jun 2027 to 7 Dec 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 May 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Dujis leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow fonio in Dujis
| Nitrogen (N) | About 30 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 30 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.
