When to plant Sweet potato in Ethiopia
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 | 11 Jun 2027 – 1 Jul 2027 opens in 36 weeks | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | about 16.8 t/ha | same |
| Harvest | From 9 Sep 2027 to 28 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 meets its needs | 80% | |
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 21 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Ethiopia leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 1 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ethiopia
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For sweet potato in Ethiopia, 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 Ethiopia
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | August 2026 to December 2026 |
| Rain in a typical year | About 780 mm in a typical farming district |
| Across its districts | From about 154 mm in the driest of 107 districts to about 1,811 mm in the wettest |
| Rainy seasons, district by district | Of 107 districts: one rainy season in 82 and two rainy seasons in 9 |
| This season's rain | Leaning wet — November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| 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. |
| What that supports | enough rain for one full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 7 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 29% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 310 mm · July to September |
|---|---|
| 17% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 117 growing days · about 520 mm · March to May |
| 10% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 226 growing days · about 1,250 mm · April to November |
| 9% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 217 growing days · about 970 mm · April to November |
| 7% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 146 growing days · about 800 mm · May to October |
| 5% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 147 growing days · about 590 mm · March to June |
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 224 growing days · about 1,140 mm · March to October |

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 |

What it takes to grow sweet potato in Ethiopia
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 67 kg per hectare |
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 134 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.
