The study was conducted in Adamawa State, Nigeria. The major thrust of this study is to assess the adoption rate of technology in Fadama III project, Adamawa State, Nigeria. Fadama III is being implemented in 20 Local Government Areas (LGA) of Adamawa State. In its four years of operation, Fadama III project has realized significant impact on household access to new and proven technologies. The results showed adoption rate of technologies among beneficiaries has increased from 43.75% before the inception of the project to 96.255% after the project intervention. This indicates 50% increase against only 20% increase among the non-beneficiaries. This increase is far above the set target of 20% by Fadama III. Plant spacing (43.75%), improved breeds (40.63%) and improved seeds (38.13%) were the most widely adopted technology for both the beneficiaries and non-beneficiaries. Adoption rate of off-farm technologies (agricultural marketing and financial management) was also large. The adoption rate for the all the technologies was significant at p = 0.05, except for fish feed formulation, Cold storage, marketing and fish smoking. Yields among respondents have increased significantly due to adoption of proven technologies. The increase was higher among crop farmers (59.38%) followed by livestock farmers (48.75%). The increase in yields across all the enterprises has exceeded the set target of 20% increase except for fish production (11.25%) and agro-forestry (6.88%). The increase was more among the beneficiaries compared to non-beneficiaries. It can be concluded that project did not only influence the beneficiaries to adopt technologies for the purpose of improving their socio-economic status but it has also influenced the non-beneficiaries living in Fadama III communities to adopt technologies. The adoption rate for fisheries and agro-forestry technologies were low. This raises the need for sensitization on the importance of these technologies that are germane to their activities. It is also important for Fadama III to strengthen its support for ADP because the latter has limited funding to effectively provide its primary role of transfer of technology. Fadama III needs to harmonize existing approaches and need to use complementary systems rather than conflicting ones. [Umar, Adamu Madu.
