This study examined adoption of Information and Communication Technologies (ICTs) by agricultural science and extension teachers in Abuja, Nigeria. Specifically, the objectives are to: identify the background and demographic characteristics of agricultural science and extension teachers in the study area; examine the factors influencing adoption of ICTs by respondents and determine the challenges or constraints militating against adoption of ICTs by respondents in the study area. Data were collected from 60 purposively selected agricultural science and extension teachers in the study area. Data were analyzed using descriptive statistics SPSS 19.0, Likert scale, t-test and Logit model. Ages, teachers' experience, access to ICTs were significant factors influencing adoption of ICTs by respondents at 1% probability level. Teachers' attitude, teachers' awareness significantly influences adoption of ICTs by respondents at 5% probability level. Word processors are perceived useful in setting tests and examination question papers, while, photocopy machine was perceived ease to use to make copies of teaching materials. Access to appropriate ICTs equipment and lack of infrastructure such as irregular electricity supply are the major challenges. The study recommends easy access, awareness and use of ICTs by instructors and regular supply of electricity to improve and stimulates adoption of ICTs by respondents.
