Northern, Uganda
Known here as nsugga · mnavu · mnafu

| When to plant | 16 Jun 2027 – 6 Jul 2027 opens in 37 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 13.3 t/ha | about 25.0 t/ha |
| Harvest | From 15 Aug 2027 to 3 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 | 75% | |
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 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Napak leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 6 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For african nightshade in Napak, rain and temperature is the tightest of the three at 96%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2027 season in Napak
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 689 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +1.9 °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 | One kind of ground throughout. |

|---|---|
| Nitrogen (N) | About 53 kg per hectare |
