When to plant Amaranth in Okaku
Oshana, Namibia
Amaranth (Amaranthus spp.) is a fast, heat-loving plant that gives you two harvests from one crop — tender leaves and tiny grain.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 26 Dec 2026 – 25 Jan 2027 opens in 12 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 15.3 t/ha | about 27.8 t/ha |
| Harvest | From 25 Jan 2027 to 24 Jun 2027, depending on the planting date | |
| Ready to harvest | 30–150 days after planting | |
| Work it takes | 78–163 days per hectare, by hand | |
| Rain meets its needs | 84% | |
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 5 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Okaku is close to normal, so these dates match the pattern the area usually follows.
Planting after 25 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Okaku
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For amaranth in Okaku, the soil is the tightest of the three at 76%. 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 Okaku
| 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 571 mm |
| This season's rain | Rain close to usual — plan around about 571 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 95% of this area. |
| 95% | 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 560 mm · December to April |
|---|---|
| 5% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 125 growing days · about 530 mm · December to April |

What it takes to grow amaranth in Okaku
| Nitrogen (N) | About 61 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 76 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 | 78–163 days per hectare, by hand |
These are the nutrients a amaranth 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.
