When to plant Cotton in Sigor
West Pokot, Kenya
Known here as pamba
Cotton is grown for one thing: the soft white fibre — the lint — that grows wrapped around the seeds inside a pod called a boll.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 11 Mar 2027 – 31 Mar 2027 opens in 23 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.6 t/ha | about 4.0 t/ha |
| Harvest | From 8 Aug 2027 to 27 Oct 2027, depending on the planting date | |
| Ready to harvest | 150–210 days after planting | |
| Work it takes | 91–187 days per hectare, by hand | |
| Rain meets its needs | 59% | |
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 31 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sigor is close to normal, so these dates match the pattern the area usually follows.
Planting after 31 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sigor
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cotton in Sigor, the lie of the land is the tightest of the three at 88%. 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 Sigor
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to August 2027 |
| Rain in a typical year | About 581 mm |
| This season's rain | Rain close to usual — plan around about 581 mm falling roughly when it always does |
| What that supports | enough rain for one short crop, and only if timed to it, 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 57% of this area. |
| 57% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 156 growing days · about 590 mm · March to August |
|---|---|
| 12% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 281 growing days · about 970 mm · March to December |
| 12% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 263 growing days · about 780 mm · March to December |
| 8% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 333 growing days · about 1,210 mm · February to January |

What cotton needs to grow here
| Soil it likes | well-drained sandy loam, loam, clay loam or clay soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Spacing | 90 cm between rows, 25 cm between plants |

What it takes to grow cotton in Sigor
| Planting material | About 80,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 45 kg per hectare |
| Phosphate (P₂O₅) | About 22 kg per hectare |
| Potash (K₂O) | About 48 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 | 91–187 days per hectare, by hand |
These are the nutrients a cotton 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.
