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.
