Abstract: The study attempted to appraise the activities of the national fadama development project in Ogun state, Nigeria. A total of 100 fadama farmers were randomly selected from the four Ogun State Agricultural Development Programme’s (OGADEP) zones in the state while, 20 members of staff of the OGADEP were also sampled. Both the interview schedule and structured questionnaire were used for interviews. The study found that age, family size, gender, educational level and frequency of extension contact made significant contribution to the prediction of the adoption of tube well/wash bore, improved seeds and inorganic fertilizer. The Pearson Product Moment Correlation (PPMCC) reveals that there is a significant positive correlation (r = 0.568; <0.05) between improved technology adoption and the benefits derived from the project. The multiple regression analysis results indicated that strong F-values of 2.682, 4.651 and 3.249 show the various independent variables as being significant explanatory variables for tube well/wash bore, improved seeds and inorganic fertilizer adoption, respectively. The chi-square (χ²) result shows that the farmer’s personal characteristic had no influence on the benefits derived from the project. Sequel to the findings from the study, recommendations included the provision of credit facilities to the fadama farmers and adequate mobility for the extension staff of the project to help improved the farmers productivity.
