Corn Yield Contest, 1920
Is Version Of
The Iowa Corn and Small Grain Growers' Association recognizes tat there are large differences in the yielding ability of varieties and of strains of the same variety of corn and therefore has inaugurated a contest to determine the highest yielding kinds for the different sections of the State.
In order to locate the highest yielding seed and prove definitely which will produce the most bushels of sound and mature corn, the state association proposes to plant, side by side under absolutely uniform conditions of soil, cultivation and other factors, a large number of samples in each section of Iowa. Computed on a uniform moisture basis, the differences in yield will be due directly to the breeding or heredity quality that comes from our seed.
