When to plant African nightshade in Mambéré
République centrafricaine
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.
| Measure | Rain-fed | With irrigation |

| When to plant | 1 Apr 2026 – 30 Sep 2026 closed for this season | 21 Jan 2026 – 1 Jan 2027 |

| Harvest | From 31 May 2026 to 28 Jan 2027, depending on the planting date | |

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 15 Apr 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mambéré is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mambéré
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For african nightshade in Mambéré, the lie of the land is the tightest of the three at 60%. 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 season in Mambéré
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to November 2026 |
| Rain in a typical year | About 1,297 mm in a typical farming district |
| Across its districts | From about 1,292 mm in the driest of 4 districts to about 1,334 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 1,297 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.0 °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 all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 68% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 255 growing days · about 1,300 mm · March to November |
|---|---|
| 28% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 293 growing days · about 1,330 mm · March to December |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 300 growing days · about 1,340 mm · March to December |
