Sowing and irrigation strategies for improving rainfed tef (Eragrostis tef (Zucc.) Trotter) production in the water scarce Tigray region, Ethiopia

Field experiments conducted under rainfed agriculture for three consecutive years (2008–2010) revealed that water stress at the late season is the most limiting factor for the productivity of tef (Eragrostis tef (Zucc.) Trotter) in Tigray, Ethiopia. Early sowing and one irrigation application late in the growing season, were evaluated with the AquaCrop model as management strategies to improve productivity. Simulations were run for three...
