Dodoma, United Republic of Tanzania
Known here as tango
Cucumber is a fast, thirsty climbing vine grown for its crisp young fruit — picked small and often, before the seeds inside go hard.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 15 Feb 2027 – 17 Mar 2027 opens in 20 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 23.8 t/ha | about 40.0 t/ha |
| Harvest | From 1 Apr 2027 to 26 May 2027, depending on the planting date | |
| Ready to harvest | 45–70 days after planting | |
| Work it takes | 120–247 days per hectare, by hand | |
| Rain meets its needs | 96% | |
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 7 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kongwa is close to normal, so these dates match the pattern the area usually follows.
Planting after 17 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kongwa
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cucumber in Kongwa, 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 2026/27 season in Kongwa
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to May 2027 |
| Rain in a typical year | About 542 mm |
| This season's rain | Rain close to usual — plan around about 542 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 short crop, and only if timed to it, 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 73% of this area. |
| 73% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 172 growing days · about 560 mm · November to May |
|---|---|
| 19% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 184 growing days · about 680 mm · November to May |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 188 growing days · about 680 mm · November to May |

What cucumber needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Rain it needs | About 1,000–1,200 mm across the season |

What it takes to grow cucumber in Kongwa
| Nitrogen (N) | About 43 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 71 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 | 120–247 days per hectare, by hand |
These are the nutrients a cucumber 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.
