When to plant African nightshade in Eritrea
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 |

| Fit | Favourable | |
| When to plant | 3 Jul 2027 – 13 Jul 2027 opens in 39 weeks | 7 Dec 2026 – 1 Jan 2027 |
| Expected harvest | 10.3–13.4 t/ha | about 23.2 t/ha |
| Harvest | From 1 Sep 2027 to 10 Nov 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 meets its needs | 90% | |
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 3 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Eritrea is close to normal, so these dates match the pattern the area usually follows.
Planting after 13 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Eritrea
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For african nightshade in Eritrea, 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 Eritrea
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2026 to September 2026 |
| Rain in a typical year | About 408 mm in a typical farming district |
| Across its districts | From about 33 mm in the driest of 58 districts to about 656 mm in the wettest |
| Rainy seasons, district by district | Of 58 districts: one rainy season in 40 and two rainy seasons in 1 |
| This season's rain | Rain close to usual — plan around about 408 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.8 °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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 62% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 190 mm · July to September |
|---|---|
| 19% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 91 growing days · about 450 mm · June to September |
| 9% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 86 growing days · about 570 mm · June to September |
| 3% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 170 mm |
| 3% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 340 mm · July to September |

What african nightshade needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.5 |
| Spacing | 40 cm between rows, 20 cm between plants |
| Feed it most with | nitrogen, phosphorus and potassium |
What it takes to grow african nightshade in Eritrea
| Planting material | About 125,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 54 kg per hectare |
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 67 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. |
| Hand work | 103–191 days per hectare, by hand |
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.
