Agricultural broadcasts on radio play a major role in agricultural extension and rural development in Nigeria due to the low ratio of extension agents in relation to the farming population. The broadcasts have been on air for some time and therefore there is a need to investigate their acceptance among the rural dwellers in Southwestern Nigeria. Multistage random sampling technique was used to select 450 respondents from three out of the six states that make up Southwestern Nigeria. They were asked to respond to an interview schedule designed for the study. Out of the returned schedules, 438 were found suitable for analyses. Results showed that agricultural broadcasts enjoyed wide listenership (94.1%) among the respondents, many of whom (69.0%) had medium listenership index (64.3%). Rural dwellers' educational attainment was significantly related to listenership of rural development broadcasts (chi[superscript 2] = 69.619), while there was no significant relationship between rural dwellers' perception (r = -0.080, P greater than 0.05) of agricultural broadcasts and listenership of agricultural broadcasts. Since agricultural broadcasts enjoyed wide listenership and were found to be potentially beneficial to the rural dwellers, they should be sustained, while avenues of improving the programming should be explored.
