Wesley Sylvester started in the seed business while farming in Riley County, Kansas in 1946. He sold wheat, oats and sorgo seed. When the corporation was formed, the name Sylvester Ranch was used due to the involvement in the cattle business. It has stuck through the years even as the focus of the company has changed to seed.
