When to plant Finger millet in Guinée
Finger millet (rapoko, rukweza, zviyo, wimbi, uphoko, mawere, dagussa, uburo) is a hardy highland grain that grows where maize and sorghum give up — high up cool slopes and right through dry spells that would wilt other crops.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 12 May 2027 – 30 Aug 2027 opens in 32 weeks | 1 May 2026 – 17 Nov 2026 |
| Expected harvest | about 2.7 t/ha | about 2.1 t/ha |
| Harvest | From 10 Aug 2027 to 7 Jan 2028, depending on the planting date | |
| Ready to harvest | 90–130 days after planting | |
| Work it takes | 74–124 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 12 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Guinée is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Guinée
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For finger millet in Guinée, 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 Guinée
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2026 to November 2026 |
| Rain in a typical year | About 2,340 mm in a typical farming district |
| Across its districts | From about 1,022 mm in the driest of 34 districts to about 3,632 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 2,340 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.8 °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 one typical farming district's, not a figure for the whole of this area. |
| 80% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 216 growing days · about 1,400 mm · April to November |
|---|---|
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 315 growing days · about 2,050 mm · February to December |
| 6% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 280 growing days · about 1,790 mm · March to December |
| 3% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 156 growing days · about 920 mm · May to October |

What finger millet needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.0 |
| Rain it needs | About 500–1,000 mm across the season |
| Spacing | 25 cm between rows, 10 cm between plants |
| Feed it most with | nitrogen and phosphorus |
What it takes to grow finger millet in Guinée
| Nitrogen (N) | About 35 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 19 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 | 74–124 days per hectare, by hand |
These are the nutrients a finger millet 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.
