When to plant Bambara groundnut in Sidi Baizid
Djelfa, Algeria
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 | 1 May 2027 – 30 Jun 2027 opens in 30 weeks |

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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sidi Baizid 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.

What it takes to grow bambara groundnut in Sidi Baizid
| Planting material | About 125,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 100 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 20 kg per hectare |
| Potash (K₂O) | About 50 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.
