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 2 Mar 2027. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Aldai is close to normal, so these dates match the pattern the area usually follows.

Planting after 11 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Aldai

Rain and temperature 96%
The soil 96%
The lie of the land 30%

For cowpea in Aldai, 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.

What it takes to grow cowpea in Aldai

Planting materialAbout 90,000 plants per hectare
Nitrogen (N)About 42 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)About 8 kg per hectare
Potash (K₂O)About 15 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.
