Weed is one the major challenges faced by farmers in cassava production. This has lead to development of new weed management technologies, but the adoption of these technologies by farmers has been an issue in research. Hence, researchers have longed sorted to understand related factors that influences farmers’ decision on adoption of agricultural technologies as related to weed management control by addressing socio-cultural and environmental variables but isolating the psychological factor and the medium for technology transfer (extension programme). Thus, the interest of this study is to evaluate the relative impact of psychological and farmers’ field school programme on farmers’ adoption decision on weed management technologies by adopting a descriptive research design. Purposive sampling technique was used in selecting 504 respondents from the sampled 8 sites of Farmers’ Field School programme established in four LGAs in Abia State. Questionnaire instruments were used to collate data and analysis was done using Pearson-Product Moment Correlation and Multiple Regression. Three research questions were raised and answered. The results of findings showed that the five independent variables (farmers’ perceptual belief, learning attitude, self-determination, motivation and farmers’ field school programme) had significant correlation with the dependent variable (weed management technology adoption). Also, the five predictor variables correlated positively with weed management technology adoption amongst cassava farmers in Abia State. In view of these findings, researchers concludes that farmer’s intention to accept new weed management technologies are being influenced by some psychological factors and the extension programme being used. These factors are germane to influencing weed management control amongst cassava farmers. This research recommends that these psychological parameters should be incorporated into the farmers’ field school training packages for an effective productivity amongst farmers as this determine to a greater extent the acceptance level of new technologies towards weed management.
