Which of the following methods of agricultural extension aims at reaching a large number of farmers at the same time?

The method of agricultural extension that aims at reaching a large number of farmers at the same time is the mass method. The mass method involves the dissemination of information to a large number of farmers simultaneously through mass media such as radio, television, newspapers, and mobile phones. This method is useful for reaching a large number of farmers who are scattered over a wide geographical area. The mass method is often used to provide information on new farming techniques, weather forecasts, disease outbreaks, and market prices, among others. By using mass media, extension workers can communicate with farmers in a cost-effective and efficient manner, without the need for face-to-face contact. However, the mass method has some limitations, such as the lack of interaction between the extension worker and the farmers, which can lead to a lack of feedback and understanding of the farmers' needs and challenges. Additionally, the mass method may not be effective for reaching farmers who do not have access to mass media, such as those in remote areas. In summary, the mass method of agricultural extension aims at reaching a large number of farmers at the same time through mass media, such as radio, television, newspapers, and mobile phones. It is a cost-effective and efficient method, but it has some limitations, such as the lack of interaction and feedback from farmers.
