When to plant African nightshade in Ouled Hellal
Medea, Algeria
African nightshade (Solanum scabrum — mnavu, managu, osuga, nsugga, umsobo) is one of Africa's most-loved traditional leafy vegetables: soft, dark, iron- and vitamin-rich leaves that cook down fast and sell steadily at market.
| Fit | Favourable |
|---|---|
| When to plant | 1 May 2027 – 29 Aug 2027 opens in 30 weeks |
| Expected harvest | about 14.5 t/ha |
| Harvest | From 30 Jun 2027 to 27 Dec 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 103–191 days per hectare, by hand |
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 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ouled Hellal is close to normal, so these dates match the pattern the area usually follows.
Planting after 29 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ouled Hellal
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For african nightshade in Ouled Hellal, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
