ABSTRACT Teff is a major cereal crop which is indigenous to Ethiopia, produced for consumption and market. However, its productivity is very low. Teff row planting technology was introduced by Ministry of Agriculture and Natural Resources and its partners to increase productivity and improve food security. To get the expected benefit, smallholder farmers should adopt the technology as recommended. Hence, this study looks in to determinants of adoption of Teff row planting technology in Moretna Jiru woreda in 2015 cropping year. In this study, multistage sampling technique was employed to select 145 sampled households. Both primary and secondary data were collected and analyzed using SPSS version 20 and STATA 11softwares. The quantitative data analysis involves simple descriptive statistics and the Tobit econometric model. The major findings of the study indicate that out of the sampled households, 67.5 % of them were adopters while 32.5% of them were not adopters of the technology. The adopters produced on average 2.3tones of Teff grain per hectare and most of them applied the technology willingly. The likert scale analysis result indicates that all adopters have found to have positive attitude towards the importance of Teff row planting technology on yield increment. This indicates that they have generally developed a positive attitude towards the technology. The descriptive analysis result indicates that out of the seventeen explanatory variables, eleven of them were found to have positive and significant relationship with the adoption and intensity use of Teff row planting technology. On the other hand, the Tobit model analysis result indicates that: sex, level of education, family size, farming experience, off farm income, contact with agricultural extension agents and attending in field days were found to have positive and significant influence on the probability of adoption and intensity of use of Teff row planting technology. Hence, government should give strong emphasis to increase women participation in Teff row planting technology and to strengthening rural informal education at different levels for youth and adults. On the other hand, development agents should back up farmers with training and organization of field days. Moreover, government needs to create off farm income generating activities for farmers. In general, policy and development interventions should give strong emphasis to support the improvement of this technology, to improve the level of adoption, increase productivity and income of rural farmers.
