The desired change would depend to a great extent on the speed with which the technologiesand innovations are made available to the ultimate unit of their utilization. If the technologies couldfit well with current farming methods and users could understand clearly, being economically feasibleto use, then small farmers accept and apply the innovations in their daily practices. It must be stressedthat a large number of innovations in farming are being released without having the mentionedcharacteristics, so the innovations end up not being adopted by small farmers. In order to avoid delayin technology adoption and eliminate inaction, farmers’ needs, and their indigenous knowledge baseshould be taken into consideration. Extension workers who function as a link between farmers andresearch institutes, are in a proper position to take farmers’ indigenous knowledge to researchscientists. By utilization and integration of indigenous knowledge base, agricultural scientists coulddevelop an appropriate technologies or innovations suitable for small farmers’ condition. The mainpurpose of this study was to assess the extension workers’ attitude toward indigenous knowledge anddetermine its relation with the extension workers’ professional characteristics (r); and determine howmuch of the variance in extension workers’ attitude could be explained by independent variables ofthe study (R2). The population of this study consisted of all 300-extension workers in the province ofAzarbiajan, which is a northwestern province in Iran. By a complete randomized sampling technique,210 of the staff were selected for the study. After a second following up on the participants, an81.42% return rate was achieved for the study. Examining the differences between early and laterespondent; and between respondent and non-respondents indicated no statistically significantdifferences on dependent variables measured. A questionnaire was designed to measure theprofessional staffs’ attitude toward indigenous knowledge base. Content validity of the attitudequestionnaire was achieved by panel of experts in the field of agricultural extension and ruralsociology. A pilot study was conducted to determine the reliability of the questionnaires for thisstudy. A Cronbach Alpha, reliability coefficient of 0.81 was achieved for the questionnaire.
