When to plant Amaranth in Nkoranza South
Bono East, Ghana
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 | 25 Mar 2027 – 28 Aug 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 18.9 t/ha | about 27.8 t/ha |
| Harvest | From 24 Apr 2027 to 25 Jan 2028, 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 20 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Nkoranza South leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 28 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Nkoranza South
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For amaranth in Nkoranza South, the lie of the land is the tightest of the three at 76%. 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 season in Nkoranza South
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | February 2026 to November 2026 |
| Rain in a typical year | About 1,157 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| 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 a long crop, or two in a year, 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 71% of this area. |
| 71% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 273 growing days · about 1,150 mm · March to November |
|---|---|
| 29% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 268 growing days · about 1,120 mm · March to November |

What it takes to grow amaranth in Nkoranza South
| Nitrogen (N) | About 76 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 94 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.
