| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 22 Mar 2026 – 20 Sep 2026 closed for this season | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.8 t/ha | about 2.5 t/ha |
| Harvest | From 21 May 2026 to 18 Jan 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 50–105 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 4 Apr 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Lagos Mainland 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 20 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Lagos Mainland
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cowpea in Lagos Mainland, 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 Lagos Mainland
| 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 1,388 mm |
| This season's rain | Leaning dry — September and October look 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. |
| 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 50% of this area. |
| 50% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 294 growing days · about 1,410 mm · March to December |

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

What it takes to grow cowpea in Lagos Mainland
| Planting material | About 90,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 108 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 22 kg per hectare |
| Potash (K₂O) | About 40 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 50–105 days per hectare, by hand |
These are the nutrients a cowpea 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.
