When to plant Onion in Talata Mafara
Zamfara, Nigeria
Known here as albasa
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.

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 1 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Talata Mafara is close to normal, so these dates match the pattern the area usually follows.
Planting after 11 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Talata Mafara
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2027 to October 2027 |
| Rain in a typical year | About 696 mm |
| This season's rain | Rain close to usual — plan around about 696 mm falling roughly when it always does |
| 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 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 96% of this area. |
| 96% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 150 growing days · about 720 mm · May to October |

|---|---|
| Nitrogen (N) | About 37 kg per hectare |
