Groundnut (peanut) is a low, leafy legume that does something no other crop in your field does: it flowers above the ground, but then each fertilised flower sends a little stalk — a peg — down into the soil, and the nut grows and fills underground. Because the plant makes its own nitrogen at its roots, it asks for very little fertiliser — but it does need loose soil the pegs can enter, calcium in the pod zone when it flowers, and above all a fast, clean dry-down after lifting, so the nuts store free of the hidden mould poison called aflatoxin. Quick-maturing Spanish/bunch types (about 90–110 days) and slower spreading Virginia/runner types (120–150 days) grow the same way — you can tell which you have by how the plant sits on the ground: a bunch type stands upright in a tight clump, while a runner type trails its stems flat and spreading over the soil. This guide is timed for a Spanish/bunch type of around 105 days.

Growing groundnut, stage by stage
Your groundnut season, step by step — from a deep, loose seedbed and clean seed, through planting, flowering and the pegs that carry your pods underground, to lifting and drying fast so the crop stores clean and free of aflatoxin.
- Get your field and inputs ready
- Plant and get a full, even stand
- Grow the canopy — and finish weeding before pegging
- Flowering and pegging — the pods form now
- Fill the pods and keep aflatoxin out
- Lift and cure (dry fast to beat aflatoxin)
- Dry, shell and store — aflatoxin-safe

Frequently asked questions
How long does groundnut take to grow?
Groundnut takes about 90–150 days from sowing to maturity, though the exact length varies with variety, temperature and how the season runs.
What spacing should I use for groundnut?
Space groundnut rows about 45 cm apart, with roughly 9 cm between plants within the row.
How deep should groundnut be planted?
Sow groundnut at about 5–7 cm deep. Shallower risks drying out; deeper wastes seed energy before the shoot reaches light.
What pests and diseases attack groundnut?
The ones covered in this guide are Bacterial wilt, Bruchids (bean and cowpea weevils), Charcoal rot. Each has its own page explaining how to identify, scout for and control it.
