Abstract: This study investigated the crop farmers’ (who are also rearing sheep and goat) perception of Moringa oleifera in Osun, Ekiti and Oyo states of southwestern Nigeria. Specifically, it identified the farmers’ socio-economic attributes; their awareness, knowledge and willingness to plant Moringa oleifera and also established the relationship between their perception of the plant and some of their selected socio-economic characteristics. Pre-tested and validated structured interview schedule was designed and used to elicit information from one hundred and thirty-nine farmers that were identified across the region using snow-ball technique, aside the presentation of the plant (Moringa oleifera) to individual farmers for identification. Also, unstructured key informants’ interviews were conducted to probe into some of the issues that were not satisfactorily buttressed during the administration of structured interview. Simple descriptive statistical techniques such as frequency counts, percentages, mean and bar chart were used to summarize the data collected, while the Pearson correlation and Chi square analyses were, respectively, used to establish the relationship and association between the respondents’ perception of Moringa oleifera and some of their selected socio-economic characteristics. Majority of the farmers in this region were male (59.71%), Christians (81.29%) and educated (Over 60.00%) with 51 years mean age and N177, 639:00 mean income per annum. The study further revealed that many (61.87%) of the farmers was ignorance of the plant, that is, they could neither identify the plant physically nor by name. However, most (92.80%) of them indicated their willingness to cultivate the plant if introduced to them. Farmers’ gender and years of knowledge of Moringa oleifera were found to significantly influence their level of perception of the plant. Popularization of the plant was, therefore, suggested using on-farm adaptive research.
