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 29 Nov 2026. That is the point in the window where the rains are most reliably established.

No seasonal forecast reaches Mamants'o yet, so these dates follow the rains it usually gets rather than this year's.

Planting after 9 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Mamants'o

Rain and temperature 96%
The soil 96%
The lie of the land 88%

For cowpea in Mamants'o, 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.

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedNovember 2026 to May 2027
Rain in a typical yearAbout 634 mm
This season's rainLeaning dry — January, February, November and December 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.
This season's heatHotter than usual — about +2.0 °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 it takes to grow cowpea in Mamants'o

Planting materialAbout 90,000 plants per hectare
Nitrogen (N)About 60 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)About 12 kg per hectare
Potash (K₂O)About 22 kg per hectare
In the shopsA 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 work50–105 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.
