When to plant Banana in Kusini Pemba
United Republic of Tanzania
Known here as ndizi
Banana and plantain are one giant perennial herb (Musa), not a tree — the tall 'trunk' is really rolled leaf-sheaths growing from an underground corm.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 21 Jan 2027 – 22 Mar 2027 opens in 16 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 27.0–27.2 t/ha | about 54.4 t/ha |
| Work it takes | 110–225 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 10 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Kusini Pemba leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kusini Pemba
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For banana in Kusini Pemba, the lie of the land is the tightest of the three at 60%. 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 2025/26 season in Kusini Pemba
| When the rains are expected | September 2025 to August 2026 |
|---|---|
| Rain in a typical year | About 1,382 mm in a typical farming district |
| Across its districts | From about 1,382 mm in the driest of 2 districts to about 1,700 mm in the wettest |
| This season's rain | Leaning wet — October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 71% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 313 growing days · about 1,650 mm · September to August |
|---|---|
| 24% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 342 growing days · about 1,650 mm · December to December |
| 5% | 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 1,040 mm · September to July |

What banana needs to grow here
| Soil it likes | well-drained loam or clay loam soil |

What it takes to grow banana in Kusini Pemba
| Planting material | About 2,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 122 kg per hectare |
| Phosphate (P₂O₅) | About 34 kg per hectare |
| Potash (K₂O) | About 408 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 | 110–225 days per hectare, by hand |
These are the nutrients a banana 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.
