When to plant Finger millet in Chake Chake
Kusini Pemba, 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.

|---|---|---|
| Fit | Favourable | |
| When to plant | 1 Sep 2026 – 16 Sep 2026 closed for this season | 10 Feb 2026 – 18 Sep 2026 |
| Expected harvest | about 2.8 t/ha | same |
| Harvest | From 30 Nov 2026 to 24 Jan 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 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Chake Chake 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 16 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Chake Chake
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For finger millet in Chake Chake, 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 2026/27 season in Chake Chake
| When the rains are expected | September 2026 to August 2027 |
|---|---|
| Rain in a typical year | About 1,382 mm |
| This season's rain | Leaning wet — October, November and December 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 71% of this area. |
| 71% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 316 growing days · about 1,410 mm · September to August |

What finger millet needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |

What it takes to grow finger millet in Chake Chake
| Nitrogen (N) | About 36 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 20 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.
