When to plant Cassava in South Ethiopia
Ethiopia
Cassava is a hardy, woody shrub grown for its fat, starchy roots — a food that grows where little else will.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 8 Feb 2027 – 28 Feb 2027 opens in 19 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 27.7 t/ha | about 20.8 t/ha |
| Bearing cycle | 240–730 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 103–180 days per hectare, by hand | |
| Rain meets its needs | 92% | |
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 8 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for South Ethiopia is close to normal, so these dates match the pattern the area usually follows.
Planting after 28 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in South Ethiopia
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 96% |
For cassava in South Ethiopia, rain and temperature is the tightest of the three at 96%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2026/27 season in South Ethiopia
| When the rains are expected | February 2026 to January 2027 |
|---|---|
| Rain in a typical year | About 1,269 mm in a typical farming district |
| Across its districts | From about 543 mm in the driest of 12 districts to about 1,492 mm in the wettest |
| Rainy seasons, district by district | Of 12 districts: one rainy season in 3 and two rainy seasons in 5 |
| This season's rain | Rain close to usual — plan around about 1,269 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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 | 8 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 23% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 291 growing days · about 940 mm · March to December |

| 9% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season no rain-fed season · about 440 mm |
| 7% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 153 growing days · about 610 mm · October to December |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 263 growing days · about 970 mm · March to November |
| 5% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 277 growing days · about 1,250 mm · February to November |

What cassava needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 4.5 and 6.5 |
| Spacing | 100 cm between rows, 100 cm between plants |

What it takes to grow cassava in South Ethiopia
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 136 kg per hectare |
| Phosphate (P₂O₅) | About 69 kg per hectare |
| Potash (K₂O) | About 194 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 | 103–180 days per hectare, by hand |
These are the nutrients a cassava 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.
