Teff [Eragrostis tef (Zucc.)] is the most important cereal crop of Ethiopia, occupying 31% area and 20% production of the total cereal crops. However, its productivity is almost stagnant, with a national average yield of meager 1.46 tonnes ha-1 mainly due to inadequate modern agronomic practices and technologies in the present production system. The urgent necessity for its higher production and productivity as a staple... Read more.
