The corn acreage in Utah is only about half that planted in barley and approximately one-fourth that sown to spring wheat. During the period 1910-30 this acreage was about equally divided into corn for grain, corn for silage, and corn fed to livestock in the field (table 1) . Since 1930 there has been a gradual increase in the acreage of corn grown for silage with the exception of the years 1936 and 1937.
