Exposure

Full sun

Soil

Light, drained, even poor and chalky; dislikes excess water and manure

Watering

Low, a frugal, drought-resistant plant

Hardiness

Fairly hardy annual (spring sowing)

Sown in autumn, protect over winter in your zone

Pollination

Self-pollinating: the flower fertilises itself

One plant is enough for a crop

Role in permaculture

One of the oldest cultivated grain legumes: it FIXES nitrogen from the air (Rhizobium symbiosis); if the seeds are harvested, a large share of that nitrogen leaves with them. Frugal, it gives keeping plant proteins on poor land. To be integrated into the rotation like the other legumes.

Good companions

Traditional companion planting (benefit not demonstrated)

Poor companions

Traditional avoidance (antagonism not demonstrated)

Seasons & availability

Nutritional & medicinal properties

For educational purposes. Not a substitute for medical advice. Effects depend on the form, the dose and personal context.

Precautions & contraindications

Eaten cooked; soaking and sufficient cooking improve digestibility.

Family behaviour: Legumes

In general, Legumes fix nitrogen from the air in most cases, thanks to the Rhizobium in their root nodules. They mainly enrich the soil for the following crops, as their residues decompose. Ideal in a rotation, before nitrogen-hungry plants such as nightshades.
