When to plant Sweet potato in Danané
Tonkpi, Côte d'Ivoire
Known here as patate douce
Sweet potato is a trailing vine you grow from vine cuttings (slips), not from seed and not by planting the root.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 4 Jun 2027 – 13 Jun 2027 opens in 35 weeks | 21 May 2027 – 10 Jun 2027 |
| Expected harvest | about 12.7 t/ha | about 20.3 t/ha |
| Harvest | From 2 Sep 2027 to 10 Nov 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 70–148 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 4 Jun 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Danané yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 13 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Danané
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For sweet potato in Danané, 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 2026 season in Danané
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,854 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.9 °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 | 2 kinds of ground. The season below is the largest that farms — about 61% of this area. |
| 61% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 320 growing days · about 1,890 mm · February to December |
|---|---|
| 38% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 288 growing days · about 1,730 mm · February to November |

What it takes to grow sweet potato in Danané
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 51 kg per hectare |
| Phosphate (P₂O₅) | About 19 kg per hectare |
| Potash (K₂O) | About 102 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. |

These are the nutrients a sweet potato 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.
