When to plant Teff in N'harea
Bié, Angola
Known here as tef
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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 7 Mar 2027 – 19 Mar 2027 opens in 22 weeks | 1 May 2027 – 10 Jun 2027 |
| Expected harvest | about 1.8 t/ha | about 3.5 t/ha |
| Harvest | From 6 May 2027 to 17 Jul 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 meets its needs | 91% | |
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 19 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for N'harea is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in N'harea
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For teff in N'harea, the lie of the land is the tightest of the three at 45%. 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 N'harea
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to May 2027 |
| Rain in a typical year | About 1,188 mm |
| This season's rain | Rain close to usual — plan around about 1,188 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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 full main crop, 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 73% of this area. |
| 73% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 245 growing days · about 1,250 mm · September to May |
|---|---|
| 27% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 247 growing days · about 1,400 mm · September to May |

Sloping ground holds back about 35% 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 N'harea
| Planting material | About 3,000,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 54 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 45 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.
