Abstract: The purpose of the study was to study the adoption status of agricultural technologies and identify factors affecting the adoption of the technologies in the coffee-based farming system of Ethiopia. The study was conducted in major coffee-growing regions of the country: Oromia and SNNP. A multistage sampling technique was employed to select the population for the study which involved both purposive and random sampling techniques. A total of 953 sample households were selected for the study. Descriptive statistics were used to analyze and summarize the collected data. A multivariate probit model was also engaged to estimate the factors that influenced the adoption of improved agricultural technologies (coffee, maize, and crossbreed cows/heifers). The result indicated that the adoption rate of improved coffee and maize varieties was 60 and 72%, respectively. The result also exhibited that 58% and 53% of coffee and maize land was covered by improved varieties, respectively in both regions. Alongside, on average only 6% of the farmers have adopted crossbreed cows/heifers. A relatively high adoption level of crossbred dairy technology was seen in the SNNP region (11%) compared to Oromia (3%). A multivariate model result indicated that improved coffee variety adoption is positively and significantly correlated with improved maize variety adoption and adoption of crossbreed cattle. The result implies that the adoption of improved coffee technologies enhances the adoption of other agricultural technologies. Land size, TV, and radio ownership have affected the adoption of improved coffee varieties positively and significantly. Distance to the all-weather road has a negative and significant relationship which implies that the adoption of coffee varieties declines as the farmers are located farther away from an all-weather road. Land size and education of the household head has also a positive and significant effect on the ...............................
