When to plant Sweet potato in Gossi
Timbuktu, Mali
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.
| Fit | Favourable |
|---|---|
| When to plant | 21 May 2027 – 29 Aug 2027 opens in 33 weeks |
| Expected harvest | about 19.4 t/ha |
| Harvest | From 19 Aug 2027 to 26 Jan 2028, 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 29 Aug 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Gossi is close to normal, so these dates match the pattern the area usually follows.
Planting after 29 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Gossi

| The soil | 60% |
| The lie of the land | 96% |
For sweet potato in Gossi, the soil is the tightest of the three at 60%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.

What it takes to grow sweet potato in Gossi
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 78 kg per hectare |
| Phosphate (P₂O₅) | About 29 kg per hectare |
| Potash (K₂O) | About 155 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.
