Cassava is a hardy, woody shrub grown for its fat, starchy roots — a food that grows where little else will.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 Jan 2026 – 1 Jan 2027 open now |
| Expected harvest | about 28.7 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-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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Assaba is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Assaba
| Rain and temperature | 96% |
|---|---|
| The soil | 60% |
| The lie of the land | 96% |
For cassava in Assaba, 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.
The 2027 season in Assaba
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | July 2027 to September 2027 |
| Rain in a typical year | About 336 mm in a typical farming district |
| Across its districts | From about 109 mm in the driest of 5 districts to about 336 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 336 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +2.0 °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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 90% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 190 mm · July to September |
|---|---|
| 10% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 85 growing days · about 350 mm · July to September |

What cassava needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|

What it takes to grow cassava in Assaba
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 141 kg per hectare |
| Phosphate (P₂O₅) | About 72 kg per hectare |
| Potash (K₂O) | About 201 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.
