When to plant Bambara groundnut in Cacuaco

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 2 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Cacuaco is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For bambara groundnut in Cacuaco, the lie of the land is the tightest of the three at 88%. 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.

What it takes to grow bambara groundnut in Cacuaco
| 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.
