When to plant Cotton in Ouara
OUADDAÏ, Tchad
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 | 16 Jun 2027 – 6 Jul 2027 opens in 37 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.5 t/ha | about 4.0 t/ha |
| Harvest | From 13 Nov 2027 to 1 Feb 2028, 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 | 55% | |
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 16 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ouara is close to normal, so these dates match the pattern the area usually follows.
Planting after 6 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ouara
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 96% |
For cotton in Ouara, the soil is the tightest of the three at 88%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2027 season in Ouara
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | July 2027 to September 2027 |
| Rain in a typical year | About 394 mm |
| This season's rain | Rain close to usual — plan around about 394 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.9 °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 short crop, and only if timed to it, 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 49% of this area. |
| 51% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 310 mm · July to September |
|---|---|
| 49% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 85 growing days · about 420 mm · June to September |

What it takes to grow cotton in Ouara
| Planting material | About 80,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 42 kg per hectare |
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 45 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.
