| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 1 Jul 2027 – 21 Jul 2027 opens in 39 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 1.6–1.8 t/ha | about 2.5 t/ha |
| Harvest | From 30 Aug 2027 to 18 Nov 2027, depending on the planting date | |

| 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 11 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for N'DJAMENA is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in N'DJAMENA
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to October 2027 |
| Rain in a typical year | About 453 mm |
| This season's rain | Rain close to usual — plan around about 453 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

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

What it takes to grow cowpea in N'DJAMENA
| 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.
