Most of the studies that have been conducted on the impacts of the Nigeria’s “FADAMA” (cultivation and farming of crops in irrigation conditions) agriculture have been silent on the aspects of exposure to and adoption of the accompanying FADAMA production practices (FPPs). However, studying the effects of these important factors is widely seen as panacea to the problems confronting the uptake of the associated FADAMA technologies. This paper uses the ‘average treatment effect (ATE)’ framework and data collected from 1177 households in South-western Nigeria to estimate the actual and potential adoption rates of FPPs and the determinants of their exposure and adoption. About 94% of the sampled households were exposed to at least one of the FPPs during the 2018/2019 survey period. The actual and potential adoption rates of at least one FPP were about 33% and 36% respectively in the same period. The main determinants of exposure and adoption were extension contact, household size, land holding, gender, input and credit access, owning ICT (Information and Communication Technology) assets and location dummies for Abeokuta north, Obafemi Owode, Odeda, Akinyele and Ido Local Government Areas (LGAs). Improving farmers’ awareness and adoption of productivity enhancing crop production practices is important. This can be achieved by enhancing credit access to facilitate inputs and ICT assets’ acquisition.
