| Fit | Favourable | |
| When to plant | 28 Mar 2027 – 18 Aug 2027 opens in 25 weeks | 11 Apr 2026 – 8 Oct 2026 |
| Expected harvest | about 1.0 t/ha | same |
| Harvest | From 26 Jun 2027 to 15 Jan 2028, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 64–134 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 8 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ngo-Ketunjia 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 18 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

| The lie of the land | 88% |
For niger seed in Ngo-Ketunjia, the soil is the tightest of the three at 88%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026 season in Ngo-Ketunjia
| 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 1,825 mm |
| This season's rain | Leaning dry — September looks 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 +0.8 °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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 56% of this area. |

These are the nutrients a niger seed 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.
