When to plant Cowpea in Mouloundou
Ogooue-Lolo, Gabon
Cowpea (nyemba, kunde, niébé, black-eyed pea) is a tough, drought-beating legume for warm country.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 9 Aug 2026 – 1 May 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.1 t/ha | same |
| Harvest | From 8 Oct 2026 to 29 Aug 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 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mouloundou 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 1 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mouloundou
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 45% |
For cowpea in Mouloundou, the lie of the land is the tightest of the three at 45%. 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 2025 season in Mouloundou
| When the rains are expected | August 2025 to August 2025 |
|---|---|
| Rain in a typical year | About 1,637 mm |
| This season's rain | Leaning dry. Plant at the early end of the window and favour quicker, more drought-tolerant crops. |
| 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 | One kind of ground throughout. |

Sloping ground holds back about 35% of yield here.
What cowpea needs to grow here
| Soil it likes | well-drained sand, sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 6.5 |
| Spacing | 75 cm between rows, 25 cm between plants |
| Feed it most with | phosphorus and potassium |
What it takes to grow cowpea in Mouloundou
| Planting material | About 90,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 13 kg per hectare |
| Potash (K₂O) | About 24 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.
