Differential Impact of Organic and/or Inorganic Fertilizer Application with Row Planting on Maize Yield Growth of Major Maize Growing Regions of Ethiopia

Résumé

This study examines the differential impact of adoption of fertilizer (organic, inorganic or both) with row planting on maize yield growth using 673 sample farm households in four major maize growing 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 fertilizer with row planting doesn't have the desired positive and significant impact on yield growth in all of the administrative regions considered except one region called Amhara. 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 appropriate and suitable improved agricultural technologies and information.
