When to plant Bambara groundnut in Katutura Central

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 31 Dec 2026. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Katutura Central 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 10 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Katutura Central

Rain and temperature	96%
The soil	96%
The lie of the land	76%

For bambara groundnut in Katutura Central, the lie of the land is the tightest of the three at 76%. 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 2026/27 season in Katutura Central

Rainy seasons	One each year — one chance to plant, so timing carries it
When the rains are expected	December 2026 to April 2027
Rain in a typical year	About 376 mm
This season's rain	Leaning dry — January and February 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 heat	Hotter than usual — about +1.9 °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	This area is smaller than the climate grid can resolve, so it reads as one kind of ground.

What it takes to grow bambara groundnut in Katutura Central

Planting material	About 125,000 plants per hectare
Nitrogen (N)	About 50 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)	About 10 kg per hectare
Potash (K₂O)	About 25 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	77–157 days per hectare, by hand

These are the nutrients a bambara groundnut 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.
