The United States Census Report for 1930 shows that approximately 25 per cent of Utah farmers were growing oats at that time. Leading counties in oat production were Sanpete, Utah, Emery, Cache, and Weber, each of which produced over 100,000 bushels. Sanpete County produced over 200,000 bushels, whereas Boxelder, Sevier, Duchesne, and Salt Lake Counties produced slightly less than 100,000 bushels each.
