| 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 | 40.5–41.5 t/ha | about 60.9 t/ha |
| Bearing cycle | 450–730 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 158–335 days per hectare, by hand | |
| Rain meets its needs | 85% | |
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 Njombe Urban 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 Njombe Urban
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 45% |
For pineapple in Njombe Urban, the lie of the land is the tightest of the three at 45%. 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 2026/27 season in Njombe Urban
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to June 2027 |
| Rain in a typical year | About 1,334 mm |
| This season's rain | Rain close to usual — plan around about 1,334 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.2 °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 | 3 kinds of ground. The season below is the largest that farms — about 86% of this area. |
| 86% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 223 growing days · about 1,250 mm · November to June |
|---|---|
| 10% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 248 growing days · about 1,380 mm · November to July |
