When to plant Finger millet in Oichili-Dimani
Grande Comore (Ngazidja), Comores
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.

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 29 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oichili-Dimani is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Oichili-Dimani
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For finger millet in Oichili-Dimani, 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.

| This season's rain | Rain close to usual — plan around about 2,071 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.7 °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. |

|---|---|
| Phosphate (P₂O₅) | About 25 kg per hectare |
