When to plant Sweet potato in Halaba
Central Ethiopia, 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 |
|---|---|---|

| When to plant | 17 Jan 2027 – 14 Feb 2027 opens in 16 weeks | 18 Sep 2026 – 21 Jan 2027 |
| Expected harvest | about 11.0 t/ha | about 27.0 t/ha |
| Harvest | From 17 Apr 2027 to 14 Jul 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |

| Rain meets its needs | 65% | |
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 31 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Halaba is close to normal, so these dates match the pattern the area usually follows.
Planting after 14 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| The soil | 76% |
| The lie of the land | 76% |

The 2027 season in Halaba
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 898 mm |
| This season's rain | Rain close to usual — plan around about 898 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.4 °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 | 3 kinds of ground. The season below is the largest that farms — about 70% of this area. |
| 70% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 262 growing days · about 960 mm · March to November |
|---|---|
| 24% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 271 growing days · about 1,000 mm · February to November |
| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 195 growing days · about 780 mm · March to October |

What it takes to grow sweet potato in Halaba
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 44 kg per hectare |
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 88 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.
