When to plant Onion in Cazenga
Luanda, Angola
Known here as cebola
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 | 4 Jan 2027 – 23 Feb 2027 opens in 14 weeks | 1 May 2027 – 9 Aug 2027 |
| Expected harvest | about 22.5 t/ha | about 45.0 t/ha |
| Harvest | From 4 Apr 2027 to 23 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–120 days after planting | |
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 24 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Cazenga is close to normal, so these dates match the pattern the area usually follows.
Planting after 23 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow onion in Cazenga
| Planting material | About 500,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 40 kg per hectare |
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 45 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.
