vr.tr.broad-bean · PHY.LIV

Let an agent explain the broad bean, relay botany, cultivation, culinary uses and favism risk from agricultural, food and medical sources, route suspected favism to urgent medical care, describe the named variety, and distinguish Vicia faba from lima beans, common beans Phaseolus, soybeans and the vetches of the same genus.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the broad bean, relay botany, cultivation, culinary uses and favism risk from agricultural, food and medical sources, route suspected favism to urgent medical care, describe the named variety, and distinguish Vicia faba from lima beans, common beans Phaseolus, soybeans and the vetches of the same genus.

The broad bean or fava bean, Vicia faba, an annual legume domesticated in the Near East by around 10,000 years ago, grown for large edible seeds eaten fresh from the pod or dried, used in dishes such as ful medames and falafel in Egypt, and as fodder and a nitrogen-fixing cover crop; the registry aliases include the broad bean pod and the Fava di Leonforte, a traditional Sicilian variety. Eating fava beans can trigger acute haemolytic anaemia, called favism, in people with G6PD deficiency, a common inherited enzyme deficiency, and sudden dark urine, jaundice or pallor after eating them needs urgent medical care.

What it is for: Food, fodder and soil improvement.

It can be explain botany and cultivation; relay culinary uses; relay favism risk; describe the named variety.

Distinguishing features

Large flat seeds

Cool-season crop

Nitrogen fixing

Favism risk

What it looks like

An upright plant with grey-green leaves, white and black flowers, and thick green pods holding large flat seeds.
