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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Chir is close to normal, so these dates match the pattern the area usually follows.
Planting after 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Chir
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For niger seed in Chir, the lie of the land is the tightest of the three at 30%. 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 season in Chir
| Rain in a typical year | About 329 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 329 mm falling roughly when it always does |
| What that supports | enough rain for one short crop, and only if timed to it, cool for part of the year, so frost sets the planting date |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 80% of this area. |
| 80% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 106 growing days · about 370 mm |
|---|---|
| 10% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 131 growing days · about 280 mm |
| 10% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 122 growing days · about 310 mm · October to March |

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 Chir
| Nitrogen (N) | About 15 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 6 kg per hectare |
| Potash (K₂O) | About 6 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.
