| When to plant | 26 Oct 2026 – 15 Nov 2026 opens in 4 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 0.7–0.9 t/ha | same |
| Harvest | From 24 Jan 2027 to 14 Apr 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 64–134 days per hectare, by hand | |
| Rain meets its needs | 92% | |
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 5 Nov 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Mbulu leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 15 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Mbulu
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to July 2027 |
| Rain in a typical year | About 898 mm |
| This season's rain | Leaning wet — January, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +0.9 °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 | 4 kinds of ground. The season below is the largest that farms — about 56% of this area. |
| 56% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 199 growing days · about 670 mm · November to May |
|---|---|
| 28% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 167 growing days · about 510 mm · November to April |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 211 growing days · about 610 mm · November to June |
| 5% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 178 growing days · about 570 mm · November to May |

What niger seed needs to grow here
| Soil it likes | clay, clay loam or loam |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.0 |
| Feed it most with | nitrogen, phosphorus and sulphur |
What it takes to grow niger seed in Mbulu
| Nitrogen (N) | About 33 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 13 kg per hectare |
| Potash (K₂O) | About 14 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 | 64–134 days per hectare, by hand |
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.
