When to plant Sweet potato in Mobaye
Basse-Kotto, République centrafricaine
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 |

| When to plant | 1 Jul 2026 – 17 Sep 2026 closed for this season | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | about 23.7 t/ha | same |
| Harvest | From 29 Sep 2026 to 14 Feb 2027, depending on the planting date | |

| 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 1 Jul 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Mobaye yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 17 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mobaye
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For sweet potato in Mobaye, 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 Mobaye

| This season's rain | Rain close to usual — plan around about 1,316 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.2 °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. |
