Six nations (USA, China, Brazil, Mexico, France, Argentina) produce 75% of the world's maize supply. The USA alone produces 39% of the total. Six states within the USA (Iowa, Illinois, Nebraska, Minnesota, Indiana and Ohio) account for 82% of this production. Iowa leads the group with 22% of total national production (which is 8.5% of total world production, approximately the total production of Mexico, France and Argentina put together). The current yield record is held by Illinois farmer Herman Warsaw, who in 1985 produced 23.5 t/ha (370 bu/A) on an 8 ha (20 A) field outside of Saybrook under rainfed conditions (607mm or 24 inches). He used high inputs of fertilizer and manure, reduced tillage, deep chisel plowing and the stay-green cultivar FS-854 planted at 92,500 seeds/ha (37,000 seeds/A).
