Which symbol on the FFA emblem represents unity?

The cross section of the ear of corn symbolizes unity in the FFA emblem. This symbol represents the foundation of American agriculture and signifies the importance of agriculture as a common denominator among all members irrespective of their background. Corn is a staple crop and is grown in every state, which highlights the organization's commitment to bringing together a diverse group of individuals who share a common interest in agriculture and leadership.

Each member, like a kernel of corn, contributes to the overall strength and unity of the organization, reinforcing the idea that everyone in FFA plays a vital role in agricultural education and the success of the community. Other symbols like the eagle, plow, and owl represent different aspects such as freedom, labor, and knowledge respectively, but it is the ear of corn that specifically embodies the sense of togetherness and collective effort within the organization.
