Faba bean (Vicia faba var. minor) is an ancient small-seeded relative of the Chinese broad bean (V. faba var. major). Faba bean is an upright plant, ranging from 1.0 to 1.5 metres (3 to 5 feet) tall. It is an annual legume with one or more strong, hollow, erect stems. Faba bean has a strong tap root with an average rooting depth of 0.6 metres (24 inches). Faba bean has compound leaves with two to six oval shaped leaflets. Faba bean is best adapted to the moist areas of Saskatchewan and does best under relatively cool growing conditions. Hot, dry spells result in wilting and may reduce seed set. Faba bean should be grown with caution in the Brown soil zones and on droughty, light-textured soils unless irrigation is available, as faba bean responds very well to irrigation.
