When to plant Sugarcane in Rufiji
Pwani, United Republic of Tanzania
Known here as muwa
Sugarcane is a tall, thick, sweet grass grown for the sugar it stores in its stalks.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 10 Oct 2026 – 30 Oct 2026 opens in 1 week | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 42.4 t/ha | about 111.2 t/ha |
| Bearing cycle | 360–540 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 150–315 days per hectare, by hand | |
| Rain meets its needs | 60% | |
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 10 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Rufiji is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rufiji
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For sugarcane in Rufiji, the soil is the tightest of the three at 76%. 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 2026/27 season in Rufiji
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 999 mm |
| This season's rain | Rain close to usual — plan around about 999 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.1 °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 96% of this area. |
| 96% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 247 growing days · about 940 mm · October to June |
|---|---|
| 4% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 244 growing days · about 1,070 mm · October to June |

What sugarcane needs to grow here
| Soil it likes | loam or clay loam |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Rain it needs | About 1,500–2,000 mm across the season |

What it takes to grow sugarcane in Rufiji
| Planting material | About 28,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 59 kg per hectare |
| Phosphate (P₂O₅) | About 23 kg per hectare |
| Potash (K₂O) | About 134 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 | 150–315 days per hectare, by hand |
These are the nutrients a sugarcane 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.
