Groundnut

Bungoma, Kenya

Known here as karanga · njugu

Groundnut (peanut) is a low, leafy legume that does something no other crop in your field does: it flowers above the ground, but then each fertilised flower sends a little stalk — a peg — down into the soil, and the nut grows and fills underground.

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 27 Dec 2026. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Mt. Elgon is close to normal, so these dates match the pattern the area usually follows.

Planting after 21 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow groundnut in Mt. Elgon

Planting materialAbout 247,000 plants per hectare
Nitrogen (N)About 33 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)About 6 kg per hectare
Potash (K₂O)About 18 kg per hectare
In the shopsA 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 work71–126 days per hectare, by hand

These are the nutrients a 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.
