When to plant Cassava in Tillabéri
Niger
Cassava is a hardy, woody shrub grown for its fat, starchy roots — a food that grows where little else will.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 Jan 2026 – 1 Jan 2027 open now |
| Expected harvest | about 35.0 t/ha |
| Bearing cycle | 240–730 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. |
| Work it takes | 103–180 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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Tillabéri is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

| The soil | 88% |
| The lie of the land | 96% |

The 2027 season in Tillabéri
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to September 2027 |
| Rain in a typical year | About 396 mm in a typical farming district |
| Across its districts | From about 215 mm in the driest of 13 districts to about 564 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 396 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 53% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 290 mm · July to September |
|---|---|
| 46% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 95 growing days · about 450 mm · June to September |

What it takes to grow cassava in Tillabéri

|---|---|
| Nitrogen (N) | About 172 kg per hectare |

These are the nutrients a cassava 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.
