When to plant Onion in Sablaale

Lower Shabelle, Somalia

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 6 Apr 2027. That is the point in the window where the rains are most reliably established.

This season's outlook for Sablaale leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.

Planting after 6 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For onion in Sablaale, 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.

What it takes to grow onion in Sablaale

Planting material	About 500,000 plants per hectare
Nitrogen (N)	About 20 kg per hectare
Phosphate (P₂O₅)	About 4 kg per hectare
Potash (K₂O)	About 23 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.
