When to plant Turmeric in N'Gourti
Diffa, Niger
Turmeric is a leafy, ginger-like plant grown for the bright orange, aromatic rhizome (underground stem) hidden beneath it — the source of the yellow spice, the dye, and its own next-season seed.
| Fit | Favourable |
|---|---|
| When to plant | 18 Sep 2026 – 8 Oct 2026 open now |
| Expected harvest | about 23.4 t/ha |
| Harvest | From 16 Apr 2027 to 4 Aug 2027, depending on the planting date |
| Ready to harvest | 210–300 days after planting |
| Work it takes | 159–282 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 18 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for N'Gourti is close to normal, so these dates match the pattern the area usually follows.
Planting after 8 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in N'Gourti
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For turmeric in N'Gourti, the lie of the land is the tightest of the three at 60%. 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 N'Gourti
| Rain in a typical year | About 35 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 35 mm falling roughly when it always does |
| What that supports | too dry for rain-fed cropping without irrigation, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

Sloping ground holds back about 15% of yield here.
What turmeric needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 50 cm between rows, 25 cm between plants |
| Feed it most with | potassium and nitrogen |
What it takes to grow turmeric in N'Gourti
| Nitrogen (N) | About 82 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 19 kg per hectare |
| Potash (K₂O) | About 140 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 | 159–282 days per hectare, by hand |
These are the nutrients a turmeric 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.
