Q

Fertilization

A

good response to nitrogen, lower to phosphorus

high nitrogen inputs increase the risk of lodging

rapid development and higher density can outgrow weeds

common fungal disease -> Teff rust

Q

Yield and storage

A

Average yield in Ethiopia reahces around 2 t/ha

Lodging is a major yield-loss factor

losses of grain during threshing and transport cause yield loss in teff

Easy storable, resistant to most pests during storage, several years of storage possible, with low humidity and away from direct sunlight

Q

Export ban

A

Export ban in 2006 from Ethiopian government

Reason:
to secure control on genetic resources
to avoid disproportionate increase in internal market price, prices increased already

Export ban was partially lifted in 2015 due to increased yields
