The present study was undertaken to explore the impact of variables on adoption of scientific dairy farming practices by the trainees and non-trainees of purposively selected KVK. The data were collected from total 300 respondents, out of it 150 trainees, who were imparted training on dairy farming under KVK and 150 non-trainees selected from same village. Out of 19 variables correlation coefficient (r) was found to be significant with respect to 10 independent variables with adoption of scientific dairy farming practices. In multiple regressions 4 variables viz., Informal sources, attitude, knowledge and scientific orientation were found significantly associated with the adoption of scientific dairy farming practices. In Path analysis Knowledge (0.648) exerted largest direct and positive influence, attitude (0.174), informal source (0.157) and scientific orientation (0.074) followed it. The impact of remaining variables was comparatively negligible hence; knowledge, attitude, informal sources and scientific orientation were considered as important crucial variables as far as direct positive effect was concerned. As concern to indirect effect out of the 19 independent variables fifteen variables, exerted positive substantial indirect effect. Knowledge exerted maximum positive substantial indirect effect (0.647) followed by attitude (0.194), informal sources (0.158), scientific orientation (0.142), economic motivation (0.0.137). Majority of the variables exerted substantial indirect effect through knowledge (X19) inferring that in association with other variables with adoption was found an important crucial variable. Hence it is exhibited that Knowledge exerted largest direct and substantial indirect effect on adoption of dairy farming practices.
