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 Dec 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Rouiba yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 9 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Rouiba
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 566 mm |
| This season's rain | Leaning dry — January, February, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +1.1 °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, with a cool spell that slows winter growth |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 75% of this area. |
| 75% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 224 growing days · about 570 mm · September to May |
|---|---|
| 25% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 224 growing days · about 580 mm · September to May |

What it takes to grow maize in Rouiba
| Planting material | About 53,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 35 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 13 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 | 82–165 days per hectare, by hand |
These are the nutrients a maize 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.
