When to plant Bambara groundnut in Woleu-Ntem
Gabon
Bambara groundnut (Vigna subterranea) is one of Africa's own beans — a tough, low, bushy plant, often grown by the women of the household on the poorest, sandiest land where maize would fail.
| Fit | Favourable |
|---|---|
| When to plant | 25 Jan 2026 – 22 Sep 2026 closed for this season |
| Expected harvest | about 1.8 t/ha |
| Harvest | From 25 Apr 2026 to 11 Mar 2027, depending on the planting date |
| Ready to harvest | 90–170 days after planting |
| Work it takes | 77–157 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 25 Jan 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Woleu-Ntem 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 22 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow bambara groundnut in Woleu-Ntem
| Planting material | About 125,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 90 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| 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. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 77–157 days per hectare, by hand |
These are the nutrients a bambara groundnut 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.
