When to plant Teff in Yatta
Machakos, Kenya
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.
| Fit | Favourable |
|---|---|
| When to plant | 21 May 2027 – 20 Jul 2027 opens in 33 weeks |
| Expected harvest | about 3.5 t/ha |
| Harvest | From 20 Jul 2027 to 17 Nov 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 88–174 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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Yatta 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 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Yatta
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 88% |
For teff in Yatta, the soil is the tightest of the three at 88%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Yatta
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | October 2026 to January 2027 |
| Rain in a typical year | About 646 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 +1.0 °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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 84% of this area. |
| 84% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 173 growing days · about 650 mm · October to January |
|---|---|
| 16% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 690 mm · October to January |

Frost and pest pressure hold back about 15% of yield here.
What teff needs to grow here
| Soil it likes | sandy loam, loam, clay loam or clay |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.2 and 5.8 |
| Feed it most with | phosphorus, nitrogen, zinc, sulphur and boron |
What it takes to grow teff in Yatta
| Planting material | About 3,000,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 105 kg per hectare |
| Phosphate (P₂O₅) | About 35 kg per hectare |
| Potash (K₂O) | About 88 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.
