When to plant African nightshade in Ouled Deide
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 23.7 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 Deide 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 Deide
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For african nightshade in Ouled Deide, the lie of the land is the tightest of the three at 76%. 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.
The 2026/27 season in Ouled Deide
| When the rains are expected | October 2026 to April 2027 |
|---|---|
| Rain in a typical year | About 532 mm |
| This season's rain | Rain close to usual — plan around about 532 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 full main crop, warm, with a cool spell that slows winter growth |
| Ground this covers | One kind of ground throughout. |

What it takes to grow african nightshade in Ouled Deide
| Planting material | About 125,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 95 kg per hectare |
| Phosphate (P₂O₅) | About 19 kg per hectare |

These are the nutrients a african nightshade 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.
