When to plant Cassava in Magharibi
Mjini Magharibi, United Republic of Tanzania
Known here as muhogo
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) | 22 Mar 2026 – 2 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 30.0 t/ha | about 35.0 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 2 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Magharibi is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Magharibi
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cassava in Magharibi, 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 2025 season in Magharibi
| When the rains are expected | August 2025 to August 2025 |
|---|---|
| Rain in a typical year | About 1,554 mm |
| This season's rain | Rain close to usual — plan around about 1,554 mm falling roughly when it always does |
| 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 | 4 kinds of ground. The season below is the largest that farms — about 50% of this area. |
| 50% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 361 growing days · about 1,560 mm · August to August |
|---|---|
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 278 growing days · about 1,340 mm · September to June |
| 14% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 264 growing days · about 1,200 mm · October to June |
| 9% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 276 growing days · about 1,350 mm · September to June |

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 Magharibi
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 147 kg per hectare |
| Phosphate (P₂O₅) | About 75 kg per hectare |
| Potash (K₂O) | About 210 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.
