The study examined adoption of recommended practices on improved rice production technology among members and non-members of Rice Farmers Associations in Kaduna and Kano States, North West Nigeria. A multi-stage sampling procedure was used for the selection of 282 respondents comprising of 141 members and 141 non-members from both States and semi-structured questionnaires were used for data collection. Data analysis was done by using descriptive statistics and Z-test. Results of the study showed that apart from number of years of formal education and use of mobile phones, there were significant differences (P<0.05) in age, household size, household labour, size of rice field and years of experience in rice production among members and non-members. In terms of adoption of recommended practices on improved rice production technology, performance of members was significantly better (P<0.05) than that of non-members in Kaduna whereas no significant difference was observed among members and non-members in Kano. Encouraging farmers to join Rice Farmers Associations alone may not lead to better adoption of improved rice production technology. It is recommended that the capacity of Rice Farmers Associations should be strengthened for them to operate as business entities and gain access to formal markets.
