Information Efficiency Scale was developed and standardized using the dimensions such as retrievability, relevancy, practicability, information content and knowledge gain by the extension personnel. The combination of Agricultural Expert System and human expertise showed the higher degree of information efficiency between the treatment groups of extension personnel.
