This book endeavours to help the readers identify the farm opinion leaders and to understand the characteristics of farm opinion leaders and farm opinion seekers. Beside this motivation, satisfaction and effectiveness of farm opinion leaders and farm opinion seekers are also demystified for a rural set up. The study of influence of family members on the head decision maker of the family is initiated. A theoretical 4 P’s model of farm opinion leadership is proposed and a new method for identification of farm opinion leaders is conceptualised.
