The impact of Ethiopia's direct seed marketing approach on smallholders' access to seeds, productivity, and commercialization por Mekonnen, Dawit Kelemework, Abate, Gashaw T., Yimam, Seid, Benfica, Rui, Spielman, David J., Place, Frank

“…These crop-specific differences in performance are likely explainable by biological differences between hybrid maize and openly pollinated varieties of wheat and teff that incentivize private sector participation in maize seed markets over wheat and teff seed markets. …”
