When to plant Groundnut in Manyatta
Embu, 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 | 18 Nov 2026 – 5 Jan 2027 opens in 7 weeks | 9 Aug 2026 – 28 Oct 2026 |
| Expected harvest | about 1.0 t/ha | same |
| Harvest | From 16 Feb 2027 to 4 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 meets its needs | 75% | |
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 30 Nov 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Manyatta leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 5 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Manyatta
| Rain and temperature | 76% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For groundnut in Manyatta, the lie of the land is the tightest of the three at 60%. 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.
The 2025 season in Manyatta
| When the rains are expected | December 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 2,002 mm |
| This season's rain | Leaning wet — December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.0 °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 35% of this area. |
| 35% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 346 growing days · about 1,810 mm · February to January |
|---|---|
| 27% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 256 growing days · about 1,170 mm · September to July |
| 16% | 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 1,720 mm · January to December |

What groundnut needs to grow here
| Soil it likes | well-drained sandy loam or sandy soil |

What it takes to grow groundnut in Manyatta
| Planting material | About 247,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 55 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 30 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.
