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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Engela is close to normal, so these dates match the pattern the area usually follows.
Planting after 22 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Engela
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to April 2027 |
| Rain in a typical year | About 614 mm |
| This season's rain | Rain close to usual — plan around about 614 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 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 97% of this area. |
| 97% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 134 growing days · about 600 mm · November to April |
|---|---|
| 3% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 133 growing days · about 570 mm · November to April |

What it takes to grow sunflower in Engela
| Planting material | About 50,000 plants per hectare |

| Nitrogen (N) | About 99 kg per hectare |
| Phosphate (P₂O₅) | About 44 kg per hectare |
| Potash (K₂O) | About 176 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. |
