Eragrostis tef, teff, Williams lovegrass, annual bunch grass, taf (Amharic: ጤፍ? ṭēff; Tigrinya: ጣፍ? ṭaff), or xaafii (Oromo), is an annual grass, a species of lovegrass native to Eritrea and Ethiopia. The word "teff" is connected by folk etymology to the Ethio-Semitic root "ṭff", which means "lost" (because of the small size of the grain).
Eragrostis tef has an attractive nutrition profile, being high in dietary fiber and iron and providing protein and calcium. It is similar to millet and quinoa in cooking, but the seed is much smaller and cooks faster, thus using less fuel.
Eragrostis tef is adapted to environments ranging from drought stress to waterlogged soil conditions. Maximum teff production occurs at altitudes of 1,800 to 2,100 m (5,900 to 6,900 ft), growing season rainfall of 450 to 550 mm (18 to 22 in), and a temperature range of 10 to 27 °C (50 to 81 °F). Teff is daylight sensitive and flowers best with 12 hours of daylight.
Teff is an important food grain in Ethiopia and Eritrea, where it is used to make injera or keyta, and less so in India and Australia. It is now raised in the US, in Idaho and Nevada. In addition to people from traditional teff-consuming countries, customers include those on gluten-restricted diets. Because of its small seeds (less than 1 mm diameter), a handful is enough to sow a large area. This property makes teff particularly suited to a seminomadic lifestyle.
