Alpha Gamma Sigma (), commonly known as Ag Sig or AGS is a national social and professional agricultural fraternity that exists on eight campuses. The mission statement of Alpha Gamma Sigma is "Preparing men for life by: coming together as scholars, living as brothers, becoming leaders of tomorrow." History 1923 The agricultural fraternity, Alpha Gamma Sigma (AGS), was first organized as a local fraternity at University of Missouri, on January 28, 1923. It was the outgrowth of a feeling among certain men that the other agricultural fraternities were disregarding the type of men essential to the proper forwarding of agriculture. During the organization and growing period of Alpha Gamma Sigma, a similar organization was going through a period of development at Ohio State University. This organization was known as the National Agriculture Club. It was established October 23, 1922. During its first year its name was changed to Tau Gamma Phi fraternity. Tau Gamma Phi rapidly grew into prominence in Ohio State campus affairs, and ranked high in scholarship. It maintained as its ideals the advancement of agriculture, scholarship, athletics and the social development of its members. 1931 Unknown to each other, Alpha Gamma Sigma at Columbia, Missouri, and Tau Gamma Phi at Columbus, Ohio, grew to be among the strongest fraternities on their respective campuses. Each had opportunities to affiliate with national fraternities but the members of these two chapters believed that their ideals were high enough to form the foundation of a new and unique organization. In March, 1931, members and alumni of Tau Gamma Phi met with members of Alpha Gamma Sigma at Columbia, and worked out a plan for joining the two groups in what now constitutes the National Chapter. A constitution was drawn up and officers consisted of the following: Clair E. Jones, president; Wayne Johnson, vice president; Don Rush, treasurer, O. E. Allen, secretary; and Delmer Glenn, historian, the Ohio chapter was designated as the Alpha chapter and the Missouri chapter as the Beta chapter. The second General Convention was held in Columbus, Ohio, November 28 and 29, 1931. The constitution and by-laws were revised and adopted. The fraternity pin and pledge pin were also adopted. A new fraternity crest was designated and put into use. The ritual, secret grip, password, raps, and motto were adopted. Royal blue and silver were selected as the fraternity colors and the red rose as the fraternity flower.
