When to plant Teff in Nyamasheke
Western Province, Rwanda
Teff (Eragrostis tef) is a fine, tufted grass that carries the smallest grain of any cereal in the world — seed almost as fine as dust.

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 3 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Nyamasheke 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 9 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Nyamasheke
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,158 mm |
| This season's rain | Leaning wet — January, February, 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 +1.2 °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 | 4 kinds of ground. The season below is the largest that farms — about 67% of this area. |

What teff needs to grow here

| Feed it most with | phosphorus, nitrogen, zinc, sulphur and boron |
What it takes to grow teff in Nyamasheke
| Planting material | About 3,000,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 90 kg per hectare |
| Phosphate (P₂O₅) | About 30 kg per hectare |
| Potash (K₂O) | About 75 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 | 88–174 days per hectare, by hand |
These are the nutrients a teff 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.
