A cost-effective way of disseminating urgent information to a large number of farmers at the same time is through mass media. Mass media refers to various channels such as television, radio, newspapers, and social media that can reach a large audience at once. These channels can be used to broadcast urgent information, such as weather alerts, disease outbreaks, market prices, and new farming practices to farmers in different locations. By using mass media, farmers can receive information quickly and simultaneously, without the need for costly travel or physical demonstrations. This makes it an efficient way to disseminate information and promote adoption of new technologies, practices or policies that can improve farming productivity and livelihoods.
