When to plant Cucumber in Oyam
Northern, Uganda
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 | 25 Mar 2027 – 16 Aug 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 25.0 t/ha | about 40.0 t/ha |
| Harvest | From 9 May 2027 to 25 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 10 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oyam is close to normal, so these dates match the pattern the area usually follows.
Planting after 16 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Oyam
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cucumber in Oyam, 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 season in Oyam
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to December 2026 |
| Rain in a typical year | About 1,191 mm |
| This season's rain | Rain close to usual — plan around about 1,191 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.4 °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 | 2 kinds of ground. The season below is the largest that farms — about 96% of this area. |
| 96% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 284 growing days · about 1,160 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 276 growing days · about 1,110 mm · March to December |

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 Oyam
| Nitrogen (N) | About 45 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 75 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.
