When to plant Cucumber in Irumu
Ituri, République démocratique du Congo
Known here as tango · concombre
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 | 22 Mar 2027 – 9 Aug 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 21.1 t/ha | about 37.9 t/ha |
| Harvest | From 6 May 2027 to 18 Oct 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-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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Irumu 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 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Irumu
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For cucumber in Irumu, 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 2026/27 season in Irumu
| When the rains are expected | February 2026 to January 2027 |
|---|---|
| Rain in a typical year | About 1,199 mm |
| This season's rain | Leaning wet — January, February, 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 +1.2 °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 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 the largest that farms — about 84% of this area. |
| 84% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 356 growing days · about 1,230 mm · February to January |
|---|---|
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 281 growing days · about 770 mm · March to December |
| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 350 growing days · about 1,240 mm · February to January |

Sloping ground holds back about 20% of yield here.
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 |
| Spacing | 150 cm between rows, 40 cm between plants |
| Feed it most with | nitrogen and potassium |
What it takes to grow cucumber in Irumu
| Nitrogen (N) | About 38 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 63 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.
