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 21 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ait Laaziz is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ait Laaziz
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For sunflower in Ait Laaziz, the lie of the land is the tightest of the three at 45%. 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 2026/27 season in Ait Laaziz
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 736 mm |
| This season's rain | Rain close to usual — plan around about 736 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 | One kind of ground throughout. |

What it takes to grow sunflower in Ait Laaziz
| Planting material | About 50,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 31 kg per hectare |
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 56 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 | 74–155 days per hectare, by hand |
These are the nutrients a sunflower 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.
