When to plant Groundnut in Samburu West
Samburu, 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 | 6 Mar 2027 – 26 Mar 2027 opens in 22 weeks | 30 Jun 2026 – 10 Feb 2027 |
| Expected harvest | about 0.7 t/ha | same |
| Harvest | From 4 Jun 2027 to 23 Aug 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 | 52% | |
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 6 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Samburu West is close to normal, so these dates match the pattern the area usually follows.
Planting after 26 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Samburu West
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For groundnut in Samburu West, the lie of the land is the tightest of the three at 45%. 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 2027 season in Samburu West
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to December 2027 |
| Rain in a typical year | About 732 mm |
| This season's rain | Rain close to usual — plan around about 732 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.2 °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 full main crop, 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 44% of this area. |
| 44% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 259 growing days · about 660 mm · March to December |
|---|---|
| 20% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 276 growing days · about 700 mm · March to December |
| 13% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 136 growing days · about 550 mm · March to June |
| 8% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 208 growing days · about 810 mm · February to June |

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

| Spacing | 45 cm between rows, 9 cm between plants |

What it takes to grow groundnut in Samburu West
| Planting material | About 247,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 38 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 7 kg per hectare |
| Potash (K₂O) | About 21 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.
