When to plant Amaranth in Riad
Nouakchott Sud, Mauritanie
Amaranth (Amaranthus spp.) is a fast, heat-loving plant that gives you two harvests from one crop — tender leaves and tiny grain.
| Fit | Favourable |
|---|---|
| When to plant | 8 Oct 2026 – 30 Jun 2027 opens in 1 week |
| Expected harvest | about 27.8 t/ha |
| Harvest | From 7 Nov 2026 to 27 Nov 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-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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Riad is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

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.
