Our roots as a company began on a diverse family farm owned by Grandpa Sylvan and Grandma Pearl Rupp. With the help of their seven children, they produced corn, beans, popcorn and strawberries along with cattle and hogs, which was pretty typical of the traditional family farm in the mid-1900s.
Grandpa Sylvan’s interest in farming was clearly demonstrated in one of our family heirlooms he created during grade school—a book of detailed, hand-drawn sketches of plants he found on the farm. This interest led him to start the “Sylvan L. Rupp Seed Farm” in 1946, which began by selling hybrid corn seed, along with producing and marketing public soybean, wheat and oat varieties to area farmers.
