When to plant Watermelon in Idah
Kogi, Nigeria
Known here as kankana
Watermelon is a warm-season trailing vine, grown flat along the ground for its big, sweet, thirst-quenching fruit — a cousin of pumpkin, cucumber and melon.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 23 Mar 2027 – 15 Sep 2027 opens in 25 weeks | 11 Apr 2026 – 17 Nov 2026 |
| Expected harvest | about 35.0 t/ha | about 50.0 t/ha |
| Harvest | From 11 Jun 2027 to 3 Jan 2028, depending on the planting date | |
| Ready to harvest | 80–110 days after planting | |
| Work it takes | 46–96 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 3 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Idah leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 15 Sep 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Idah
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For watermelon in Idah, 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 Idah
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to November 2026 |
| Rain in a typical year | About 1,334 mm |
| This season's rain | Leaning dry — September looks short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.8 °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 | 2 kinds of ground. The season below is the largest that farms — about 92% of this area. |
| 92% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 246 growing days · about 1,330 mm · March to November |
|---|---|
| 8% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 249 growing days · about 1,360 mm · March to November |

What watermelon needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |

What it takes to grow watermelon in Idah
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 77 kg per hectare |
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 112 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 | 46–96 days per hectare, by hand |
These are the nutrients a watermelon 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.
