What does the emblem of the FFA include that represents unity?

The emblem of the FFA prominently includes a cross-section of an ear of corn, which symbolizes unity among members. Corn is a staple crop and is significant in American agriculture, representing the foundation of agriculture education and the FFA's commitment to the agricultural industry as a whole. The inclusion of corn signifies that it connects all members, regardless of their individual backgrounds or states, emphasizing that FFA is a national organization. This representation fosters a sense of togetherness and shared purpose, underscoring the organization's mission to promote leadership and education in agriculture. The other symbols in the emblem each have their own meanings, such as growth and progress, but it is the ear of corn that distinctly encompasses the idea of unity among all FFA members.
