Abstract


This study examines the regional disparity in the impact of adoption of improved wheat varieties on productivity using 1,611 sample farm households in four major administrative regions of Ethiopia. Propensity score matching (PSM) technique was employed since it is an increasingly utilized standard approach for evaluating impacts using observational data. It is found that adoption of improved wheat varieties doesn't have homogenous positive and significant impact on productivity growth in all of the administrative regions considered. Thus, the study recommends that the agricultural research and extension system of the country should further consider the various differences that exist among different regions and areas of the country so as to generate and disseminate suitable improved agricultural technologies and information.

 

Key words: Impact, Wheat, Improved Varieties, Ethiopia.
