When to plant Groundnut in Mt. Elgon
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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Moderate | |
| When to plant | 1 May 2026 – 21 Jan 2027 open now | 29 Aug 2027 – 18 Sep 2027 |
| Expected harvest | about 0.6 t/ha | same |
| Harvest | From 30 Jul 2026 to 20 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 71–126 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 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.

The 2026 season in Mt. Elgon
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 1,475 mm |
| This season's rain | Rain close to usual — plan around about 1,475 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.9 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 40% of this area. |
| 40% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 1,520 mm · January to January |

| 7% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 365 growing days · about 1,470 mm · January to December |

What groundnut needs to grow here

What it takes to grow groundnut in Mt. Elgon
| Planting material | About 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 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 | 71–126 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.
