When to plant Sweet potato in 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 | 30 May 2027 – 11 Jun 2027 opens in 35 weeks | 21 May 2027 – 10 Jun 2027 |
| Expected harvest | about 23.7 t/ha | about 33.2 t/ha |
| Harvest | From 28 Aug 2027 to 8 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 30 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Côte d'Ivoire leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 11 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Côte d'Ivoire
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For sweet potato in Côte d'Ivoire, the lie of the land is the tightest of the three at 76%. 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 Côte d'Ivoire
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,305 mm in a typical farming district |
| Across its districts | From about 974 mm in the driest of 108 districts to about 1,854 mm in the wettest |
| This season's rain | Leaning dry — February, September, October and November 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 | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 43% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 240 growing days · about 1,030 mm · March to November |
|---|---|
| 32% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 282 growing days · about 1,110 mm · February to November |
| 24% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 323 growing days · about 1,400 mm · February to December |

Frost and pest pressure hold back about 15% of yield here.
What sweet potato needs to grow here
| Soil it likes | well-drained sandy, sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 6.5 |
| Rain it needs | About 750–1,000 mm across the season |
| Spacing | 100 cm between rows, 30 cm between plants |
| Feed it most with | potassium and nitrogen |
What it takes to grow sweet potato in Côte d'Ivoire
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 95 kg per hectare |
| Phosphate (P₂O₅) | About 36 kg per hectare |
| Potash (K₂O) | About 190 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 | 70–148 days per hectare, by hand |
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.
