When to plant Teff in Ongwediva
Oshana, Namibia
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 | 1 May 2027 – 20 Jul 2027 opens in 30 weeks |
| Expected harvest | about 3.5 t/ha |
| Harvest | From 30 Jun 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 1 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ongwediva is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Ongwediva
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to April 2027 |
| Rain in a typical year | About 550 mm |
| This season's rain | Rain close to usual — plan around about 550 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 90% of this area. |
| 90% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 132 growing days · about 550 mm · November to April |
|---|---|
| 10% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 127 growing days · about 540 mm · December to April |
