When to plant Onion in Ain Skhouna
Saida, Algeria
Onion is a cool-season vegetable you grow for its bulb — the swollen base of the leaves — but across sub-Saharan Africa it is most often grown as an irrigated hot dry-season crop, and it stands real heat (up to about 42 °C) as long as the water never stops.
| Fit | Favourable |
|---|---|
| When to plant | 27 Dec 2026 – 1 May 2027 opens in 12 weeks |

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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ain Skhouna is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| Nitrogen (N) | About 75 kg per hectare |
