When to plant Fonio in Moshi Urban
Kilimanjaro, United Republic of Tanzania
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 | 2 Feb 2027 – 26 Feb 2027 opens in 18 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.4 t/ha | same |
| Harvest | From 3 Apr 2027 to 26 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 14 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Moshi Urban 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 26 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Moshi Urban
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For fonio in Moshi Urban, 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.
The 2026 season in Moshi Urban
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | February 2026 to July 2026 |
| Rain in a typical year | About 719 mm |
| This season's rain | Leaning wet — February look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.1 °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 one full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 44% of this area. |
| 44% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 254 growing days · about 870 mm · October to July |
|---|---|
| 22% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 184 growing days · about 690 mm · February to June |
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 300 growing days · about 1,210 mm · October to August |
| 11% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 209 growing days · about 770 mm · February to July |

What fonio needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 6.5 |
| Feed it most with | nitrogen and phosphorus |
What it takes to grow fonio in Moshi Urban
| 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.
