Boone County White Corn Seed (110-120 days) Boone County White was created by Mr. James Riley of Boone County, Indiana back in 1874. Mr. Riley started with the variety "White Mastodon" and selected on the traits he desired such as ear size and leaf size. A few years later he released his new corn and named it Boone County White. Boone County was very popular for good reason. It is a very heavy producer of huge ears that measure 9-11" in length. That is almost a foot long! The uniform ears have 18-22 rows. Heavily leaved, which is great for shading out understory weeds. 9-11' stalks. Boone County white is a diverse corn that is used for silage, stock feed and corn meal.
