Cowpea (nyemba, kunde, niébé, black-eyed pea) is a tough, drought-beating legume for warm country.
| Fit | Moderate |
|---|---|
| When to plant | 10 Jun 2027 – 30 Jun 2027 opens in 36 weeks |
| Expected harvest | about 0.9 t/ha |
| Harvest | From 9 Aug 2027 to 28 Oct 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 30 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Chir is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Chir
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For cowpea in Chir, the lie of the land is the tightest of the three at 30%. 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 season in Chir
| Rain in a typical year | About 329 mm |
|---|---|
| This season's rain | Rain close to usual — plan around about 329 mm falling roughly when it always does |
| What that supports | enough rain for one short crop, and only if timed to it, cool for part of the year, so frost sets the planting date |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 80% of this area. |
| 80% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 106 growing days · about 370 mm |
|---|---|
| 10% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 131 growing days · about 280 mm |
| 10% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 122 growing days · about 310 mm · October to March |

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 Chir
| Planting material | About 90,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 54 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 20 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.
