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 Mar 2027 – 28 Mar 2027 opens in 23 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 20.5 t/ha | about 34.6 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 | 68% | |
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 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Savalou leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 28 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Savalou
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cassava in Savalou, the lie of the land is the tightest of the three at 88%. 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 2027 season in Savalou
| 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 1,015 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.8 °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 | 2 kinds of ground. The season below is the largest that farms — about 97% of this area. |
| 97% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 248 growing days · about 980 mm · March to November |
|---|---|
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 248 growing days · about 1,000 mm · March 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 |

What it takes to grow cassava in Savalou
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 100 kg per hectare |
| Phosphate (P₂O₅) | About 51 kg per hectare |
| Potash (K₂O) | About 144 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.
