When to plant Taro in N'Gourti
Diffa, Niger
Cocoyam, or taro (Colocasia esculenta), is a broad-leaved plant grown for its corm — a heavy, potato-like food store that swells underground — and, in some types, for its tender young leaves.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 May 2026 – 1 May 2027 open now |
| Expected harvest | about 26.6 t/ha |
| Bearing cycle | 180–540 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. |
| Work it takes | 111–233 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 1 May 2027. 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 1 May 2027 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 taro 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. |

What it takes to grow taro in N'Gourti
| Planting material | About 24,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 120 kg per hectare |
| Phosphate (P₂O₅) | About 60 kg per hectare |
| Potash (K₂O) | About 200 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 | 111–233 days per hectare, by hand |
These are the nutrients a taro 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.
