| Fit | Favourable | |
| When to plant | 27 May 2027 – 21 Jul 2027 opens in 34 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.0 t/ha | about 0.1 t/ha |
| Harvest | From 25 Aug 2027 to 18 Dec 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-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 27 May 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Arsi 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 21 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Arsi
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For niger seed in Arsi, the lie of the land is the tightest of the three at 88%. 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 2027 season in Arsi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | February 2027 to November 2027 |
| Rain in a typical year | About 1,095 mm |
| This season's rain | Leaning wet — February, October and November 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 +1.3 °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 a long crop, or two in a year, 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 32% of this area. |
| 32% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 285 growing days · about 1,090 mm · February to November |
|---|---|
| 26% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 241 growing days · about 820 mm · March to November |
| 14% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 219 growing days · about 700 mm · March to November |
| 5% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 176 growing days · about 730 mm · April to October |

Frost and pest pressure hold back about 15% of yield here.
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 Arsi
| Nitrogen (N) | About 37 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 15 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.
