Abstract: The study assessed adoption of improved food barley technologies and factors determining the adoption decision of smallholder barley producers. The study employed cross-sectional data collected from major barley growing regions of Ethiopia. Tobit, Double hurdle and Multivariate probit models along with descriptive statistics were used to analyze the data. According to the findings, average seed rate used was found within the rage of the national recommendation whereas inorganic fertilizers applied was lower than the recommendation. Crop rotation, inorganic fertilizers, soil and water conservation practices, herbicides, manure, improved varieties and row planting were used by 87%, 65%, 48%, 48%, 39%, 8% and 6%, of the producers respectively. The result indicated that encouraging membership of cooperatives and participation in food barley marketing, training the producers and improving access to input market helps to increase the adoption of inorganic fertilizer in food barley production. The extension system that focuses on demonstration and experience sharing helps to scale the adoption of improved food barley varieties. Improving accessibility of improved seed and fertilizer helps to increase adoption of food barley technologies. The result exhibited complementarity among adoption decision of the technologies; that suggested focusing on technology package is a favourable extension approach to enhance adoption of food barley technologies.
