What term describes the message factor that encompasses the idea or technology intended to be expressed?

The term that encompasses the idea or technology intended to be expressed is message content. Message content refers to the actual information, ideas, or themes that make up the message itself. It is the substance that conveys the intended meaning to the audience. In the context of agricultural extension and communication, understanding message content is crucial, as it directly affects how effectively new ideas, practices, or technologies are transmitted and understood by target audiences.

Feedback, while important in the communication process, refers to the responses or reactions from the audience regarding the message received. Message treatment involves the way the content is presented, such as the style or format, and message code refers to the symbols or language used to convey the message. These concepts are relevant to communication but do not specifically define the actual ideas or technologies being communicated. Therefore, message content is the most appropriate term to describe the core message being conveyed in this context.
