When to plant Cotton in Oum Tiour
El Oued, Algeria
Cotton is grown for one thing: the soft white fibre — the lint — that grows wrapped around the seeds inside a pod called a boll.
| Fit | Favourable |
|---|---|
| When to plant | 22 Mar 2027 – 30 Jun 2027 opens in 25 weeks |
| Expected harvest | about 3.3 t/ha |
| Harvest | From 19 Aug 2027 to 26 Jan 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-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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oum Tiour is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Oum Tiour
| Rain and temperature | 96% |
|---|---|
| The soil | 60% |
| The lie of the land | 96% |
For cotton in Oum Tiour, the soil is the tightest of the three at 60%. 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 season in Oum Tiour
| Rain in a typical year | About 102 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 102 mm falling roughly when it always does |

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 Oum Tiour
| Planting material | About 80,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 92 kg per hectare |
| Phosphate (P₂O₅) | About 46 kg per hectare |
| Potash (K₂O) | About 99 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.
