When to plant Finger millet in Tarime
Mara, United Republic of Tanzania
Known here as wimbi · ulezi
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 | 9 Aug 2026 – 2 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.7 t/ha | same |
| Harvest | From 7 Nov 2026 to 10 Jul 2027, 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 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Tarime is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Tarime
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For finger millet in Tarime, 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.

What it takes to grow finger millet in Tarime
| 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.
