Thus, a three-year experiment from 2013 to 2015 was conducted to assess the potential of crop rotation and organic matter application for recovery of the soil health and crop productivity of cultivated land in northwest Ethiopian highlands. Factorial combinations of five crop rotations [bread wheat–clover–potato (R1+); clover–bread wheat undersowing lupine–potato (R2+); potato–clover–bread wheat (R3+); bread wheat undersowing lupine–potato undersowing lupine–bread wheat (R4+); and lupine–potato undersowing lupine–bread wheat (R5+)] and four manure application rates [control without manure (M1); 2.5 t ha-1 sesbania green manure SGM (M2); 5 t ha-1 fresh cattle manure FCM (M3); and 2.5 t ha-1 SGM + 5 t ha-1 FCM (M4)] were laid out in randomized complete block design with four replications at on-station and on-farm testing sites. Interaction of crop rotation and manure application significantly improved the soil properties and crop productivity of the experimental plots. Combined applications of crop rotation and manure in a three-year period resulted in the i...

However, the productivity of the crop remains low mainly due to the limited use of improved technologies including seeds. In this study, three recently released and one old (as a check) tef varieties were evaluated on 254 lead farmers’ fields with the main aim of increasing farmers’ access to quality breed seeds.Each lead farmer was provided with breeder seeds of four improved tef varieties, namely Kora, Tesfa, Dagim,...
