Which of the following is an example of an agricultural extension method used to disseminate information to farmers?

Extension methods include: individual contacts (farm visits, office calls), group methods (demonstrations, field days, farmer groups), and mass media (radio, TV, publications).

Demonstrations on model farms are particularly effective – farmers see results before adopting. Result demonstrations show outcomes; method demonstrations teach techniques.

Effective extension uses multiple methods. Personal contact builds trust; mass media reaches many; group methods combine efficiency with interaction.
