Khenchela, Algeria
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 | 21 May 2027 – 30 May 2027 opens in 33 weeks |
| Expected harvest | about 1.3 t/ha |
| Harvest | From 20 Jul 2027 to 27 Sep 2027, depending on the planting date |

| 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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Khirane is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Khirane
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For fonio in Khirane, the lie of the land is the tightest of the three at 76%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.

|---|---|
| This season's rain | Rain close to usual — plan around about 308 mm falling roughly when it always does |

What it takes to grow fonio in Khirane
| Nitrogen (N) | About 26 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 26 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.
