When to plant Sorghum in Nyeri Town
Nyeri, Kenya
Known here as mtama
Sorghum (Sorghum bicolor — mapfunde, mtama, amabele, mapira, dawa, mashilla) is the toughest of the grain cereals: a tall, C4 grass that keeps standing and yields when heat and dry spells have already beaten maize.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 24 Nov 2026 – 28 Jan 2027 opens in 8 weeks | 30 Jun 2026 – 1 Jan 2027 |
| Expected harvest | about 3.0 t/ha | same |
| Harvest | From 22 Feb 2027 to 17 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–140 days after planting | |
| Work it takes | 92–168 days per hectare, by hand | |
| Rain meets its needs | 98% | |
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 20 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 28 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 | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For sorghum 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 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 28% of this area. |

What it takes to grow sorghum in Nyeri Town
| Planting material | About 100,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 12 kg per hectare |
| Phosphate (P₂O₅) | About 5 kg per hectare |
| Potash (K₂O) | About 14 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |

These are the nutrients a sorghum 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.
