When to plant Cassava in Calai
Cuando Cubango, Angola
Known here as mandioca
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) | 30 Oct 2026 – 19 Nov 2026 opens in 4 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 16.2 t/ha | about 28.9 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 | 61% | |
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 30 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Calai is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Calai
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |

For cassava in Calai, rain and temperature is the tightest of the three at 88%. 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 Calai
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to April 2027 |
| Rain in a typical year | About 671 mm |
| This season's rain | Rain close to usual — plan around about 671 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.7 °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 | One kind of ground throughout. |

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 |

What it takes to grow cassava in Calai
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 79 kg per hectare |
| Phosphate (P₂O₅) | About 40 kg per hectare |
| Potash (K₂O) | About 113 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.
