When to plant Rice in Westlands
Nairobi, Kenya
Known here as mchele · mpunga
Rice is a grass that lives on water.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 16 Sep 2026 – 17 Feb 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.5 t/ha | about 6.0 t/ha |
| Harvest | From 15 Dec 2026 to 17 Jul 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 69–107 days per hectare, by hand | |
| Rain meets its needs | 61% | |
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 Westlands 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 17 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Westlands
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 76% |
For rice in Westlands, the lie of the land is the tightest of the three at 76%. 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 2026 season in Westlands
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 838 mm |
| This season's rain | Leaning wet — January, February, October, November and 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 one full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 80% of this area. |
| 80% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 239 growing days · about 890 mm · February to July |
|---|---|
| 20% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 212 growing days · about 790 mm · February to June |

What rice needs to grow here
| Soil it likes | loam, clay loam or clay |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.0 |
| Spacing | 20 cm between rows, 20 cm between plants |
| Feed it most with | nitrogen and zinc |
What it takes to grow rice in Westlands
| Planting material | About 600,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 38 kg per hectare |
| Phosphate (P₂O₅) | About 12 kg per hectare |
| Potash (K₂O) | About 55 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. |
| Hand work | 69–107 days per hectare, by hand |
These are the nutrients a rice 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.
