When to plant Onion in Jere
Borno, 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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 25 Jun 2027 – 15 Jul 2027 opens in 38 weeks | 28 Oct 2026 – 7 Dec 2026 |
| Expected harvest | about 18.8 t/ha | about 41.7 t/ha |
| Harvest | From 23 Sep 2027 to 12 Nov 2027, depending on the planting date | |
| Ready to harvest | 90–120 days after planting | |
| Rain meets its needs | 91% | |
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 5 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Jere is close to normal, so these dates match the pattern the area usually follows.
Planting after 15 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Jere
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For onion in Jere, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2027 season in Jere
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to October 2027 |
| Rain in a typical year | About 468 mm |
| This season's rain | Rain close to usual — plan around about 468 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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 | One kind of ground throughout. |

What onion needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.0 |
| Spacing | 20 cm between rows, 7 cm between plants |
| Feed it most with | nitrogen, potassium and sulphur |
What it takes to grow onion in Jere
| Planting material | About 500,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 34 kg per hectare |
| Phosphate (P₂O₅) | About 7 kg per hectare |
| Potash (K₂O) | About 38 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. |
These are the nutrients a onion 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.
