RESUMO
This study investigates the adoption and impact of improved teff varieties (ITVs) on food security in North Eastern Amhara Region, Ethiopia. The result of binary probit model shows that the adoption decision of improved teff varieties is determined by total family size measured in adult equivalent, off-farm income, number of traders known by farmers, variety information from development agents and research center affects positively and distance of farmer's residence from kebele office of agriculture negatively Endogenous switching regression (ESR)model was employed to evaluate the impacts of adoption of improved teff varieties on food security. The output from ESR asserted that had the adopter households decided not to adopt, their average daily calorie intake and annual food consumption expenditure per adult equivalent would have decreased by 417.908 kilocalorie and 1096.509 Ethiopian Birr(37.8.41 dollars) respectively. Thus, policies and development endeavors targeting to realize food security should facilitate the adoption of ITVs.
