When to plant Soybean in Nyeri Town
Nyeri, Kenya
Known here as soya
Soybean (Glycine max) is a bushy, knee-high bean grown for a seed that is rich in protein and oil — good to eat, good to sell, and it leaves the soil richer for whatever you plant next.

| When to plant | 24 Dec 2026 – 29 Jan 2027 opens in 12 weeks | 20 Jul 2026 – 8 Oct 2026 |
| Expected harvest | about 1.8 t/ha | same |
| Harvest | From 24 Mar 2027 to 28 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 68–141 days per hectare, by hand | |
| Rain meets its needs | 88% | |
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 24 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Nyeri Town 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 29 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Nyeri Town
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For soybean in Nyeri Town, 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 Nyeri Town
| When the rains are expected | December 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 1,038 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 it takes to grow soybean in Nyeri Town
| Planting material | About 350,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 99 kg per hectare |
