Introduction to Eragrostis teff (Zucc.)Trotter Taxonomy: • Family: Poaceae, Genus: Eragrostis (“Love-grass”), many fodder species in drier areas such as South Africa, Australia and India -34 different cultivars found in Ethiopia -also known as Poa abyssinica, Eragrostis abyssinica
Introduction to Eragrostis teff History: • Ethiopia centre of origin and diversification • Ethiopia only country to grow Teff as food for human consumption • >66% of population relies on Teff for nutrient supply • 25% of agricultural production (1.9 mill. ha/yr) • South Africa, Yemen, India know it as a fodder genus/species
Introduction to Eragrostis teff Physiology: • Annual tufted grass • Loose or compacted panicle flowers • Grains 1-1.5mm, 2500-3000 seeds/kg • C4 pathway, tetraploid • Shallow, fibrous root system • Tolerant to: drought, water-logging, frost, acid/toxic soils, vertisols
Introduction to Eragrostis teff Uses: • Injera, bread, porrige, gruel, beer, flat bread, high protein, mineral and vitamin content (more than Maize, Sorghum and Wheat) • High quality straw and hay due to higher protein content, digestibility (65%) and palatability; low dry matter content • Fast growing ground cover against erosion • Catch-crop, nurse-crop, fallow crop • Back-up crop in case of failure of Wheat and Barley
Agronomy • 300-2500mm precipitation/year • 1500-3000m a.s.l • Matures in 2-4 months • 200-1500kg/ha, average 910kg/ha depending on practice • Similar yield to wheat although unimproved-great potential • Performs best on heavy, well drained soil
Agronomy Cultivation and sowing • Occurs mainly March to June • 4-8 cultivations with ox-drawn wooden plough to obtain fine till as seeds small • Seeds broadcast at 10-12kg/ha • Covered lightly with brush harrow to obtain good seed-soil contact • Quick germination yet slow growth until roots established
Agronomy Management • Early manual weeding at 7-10 days after sowing • Can outcompete weeds if rain adequate for fast growth • Relatively resistant to most pests and diseases • Low maintenance during growth • Eg. Farmers in Yemen simply scatter some seed on dry soil and return to harvest a good fodder crop after 45 days
Agronomy Harvest and processing • 6-10 dry days prior to harvest ideal to avoid lodging, fungal attack and shattering • End of main rainy season, September-October • Sickle harvest, very labour intensive • Small seed size requires gentle handling against shattering • Threshed using cattle, who also feed on the straw • Can be stored well for 3 years for seed, 5 years for food
Marketing • Three distinct colour classifications determine price: • White, red and brown • White most expensive (£20-35/100kg) • Red and brown (£15-20/100kg) • High price around festive season, especially for white Teff • Sold unprocessed, whole grain • Households process further by taking grain to mills
Advantages: Highly nutritious Great agronomic potential Can grow in a wide ecological range Tolerant to drought, water-logging etc Soil conservation and rehabilitation Fast maturing, backup in cases of disaster High market value Disadvantages: Small seed Shatters Easily “lost” Labour intensive Need for improvement of genetic, technical and labour aspects Advantages vs Disadvantages
