Effectiveness index of expert system applications was worked out using seven statements and the results showed that pedagogy (as a means to effective learning through expert system) having highest effectiveness index. The findings demonstrate that most of the respondents belonged to middle age category, holding with master degrees; attended training on lCT. It was also found that most of the respondents having high innovativeness and accessibility, forinat clarity and information content of the expert system perceived as high.

    The present study entitled ‘Performance effectiveness of technology dissemination system of State Department of Agriculture in Kerala and Andhra Pradesh: A comparative analysis’ was conducted in Kerala and Andhra Pradesh states during 2014-2017 covering 200 extension professionals and 100 farmers form both the states with equal proportions. Agricultural extension workers of State Department of Agriculture are personnel who are responsible for meeting the goals of extension system.

This necessitates the present study with the objective of assessing and comparing performance effectiveness of State Department of Agriculture in Kerala and Andhra Pradesh vis-a-vis technology dissemination system. Comparative analysis of technology dissemination systems of Kerala and Andhra Pradesh would allow inter-scalability of technologies. The findings demonstrated that most of the extension professionals with respect to Kerala as well as Andhra Pradesh states have moderately favorable attitudes towards technology dissemination system of State Department of Agriculture (SDA).

Comparative analysis of Performance effectiveness index of technology dissemination system of State Department of Agriculture (SDA) among Kerala and Andhra Pradesh extension personnel have shown that there was significant difference. Performance effectiveness index of Kerala extension professionals was influenced by the factors like experience, training, job satisfaction, participation efficiency and achievement motivation. Performance effectiveness index of Andhra Pradesh extension professionals was influenced by the factors like experience, training, organizational commitment, innovation proneness and participation efficiency. The study also revealed that most of the farmers with respect to Kerala as well as Andhra Pradesh states, perceived that technology dissemination system of State Departments of Agriculture (SDA) was moderately favourable.
