General Information and Agronomic Aspects

| Geographical Distribution of Teff in Africa |
The word tef is thought to originate from the Amharic word teffa, which means "lost" (due to small size of the grain), or from the Arabic word tahf used by Semites in South Arabia.
Teff is an important food grain in Ethiopia and Eritrea, where it is used to make injera. Because of its small seeds (less than 1 mm diameter), one can hold enough to sow an entire field in one hand. This property makes teff particularly suited to a seminomadic lifestyle.
Climate conditions, soil and water management:
It is adapted to environments ranging from drought stress to water logged soil conditions. Maximum teff production occurs at altitudes of 1800 to 2100 m, with a temperature range of 10 to 27 °C. Average annual rainfall is about 750-1000 mm in the central Ethiopian highlands. Maximum rainfall in the area of cultivation is about 2500 mm. However, teff could produce good yields at much lower annual rainfalls: for most cultivars 300-500 mm of rainfall per growing season is adequate. Early maturing varieties (60-75 days) can do with less than 300 mm of seasonal rainfall. Teff is day length sensitive and flowers best during 12 hours of daylight.Propagation and Planting:
Ethiopian farmers grow tef either as a staple or as a standby. As a staple, they plant it like other cereals, but they normally sow it late and harvest it well into the dry season. As a standby, they wait until their main crops maize, sorghum, or maybe wheat shows signs of failing. Then they sow a fast-maturing tef as a backup source of sustenance in case of disaster. (Lost Crops of Africa: Vol. I: Grains (1996)) Husbandry:
Teff requires little care once it is established. Its rapid growth stifles most weeds; few diseases and pests attack it; and it is said to produce well without added nutrients. However, in most places tef will respond to fertilizers. In Ethiopia, large yield improvements can be achieved by applying techniques that are already known: careful land preparation, use of selected seeds, fertilization, sowing and weeding at the optimum time, and disease and pest control, for example. (Lost Crops of Africa: Vol. I: Grains (1996)) Harvesting:
Tef threshes well with standard methods and equipment. Very early-maturing types are ready to harvest in 45-60 days; early types in 60-120 days; and late types in 120-160 days.Yields range from 300 to 3,000 kg per hectare, or even more. Although the national average in Ethiopia is 910 kg per hectare, yields of 2,000-2,200 kg per hectare are considered routinely attainable if good agronomic practices are carefully followed. Yields of 2,000 kg per hectare have been achieved on South African farms also, although storms have sometimes leveled the fields, resulting in large losses.
The grain is easy to store and will survive for many years in traditional storehouses without damage by insects. This makes it a valuable safeguard against famine. (Lost Crops of Africa: Vol. I: Grains (1996))
