When to plant Fonio in Nzema East
Western, Ghana
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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 15 Feb 2027 – 16 May 2027 opens in 20 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.3 t/ha | same |
| Harvest | From 16 Apr 2027 to 13 Sep 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 5 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Nzema East leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 16 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Nzema East
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For fonio in Nzema East, the lie of the land is the tightest of the three at 60%. 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.
The 2026 season in Nzema East
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 1,684 mm |
| This season's rain | Leaning dry. Plant at the early end of the window and favour quicker, more drought-tolerant crops. |
| This season's heat | Hotter than usual — about +0.6 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |
| What that supports | enough rain for a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 97% of this area. |
| 97% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 361 growing days · about 1,620 mm · January to January |

What it takes to grow fonio in Nzema East
| 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.
