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 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ville de Maradi is close to normal, so these dates match the pattern the area usually follows.
Planting after 10 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Ville de Maradi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to September 2027 |

| This season's rain | Rain close to usual — plan around about 404 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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 55% of this area. |
| 55% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 89 growing days · about 410 mm · June to September |

What it takes to grow bambara groundnut in Ville de Maradi
| 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.
