The seed corn situation in the corn-belt states this year is serious. Not as much seed corn was saved last year as usual, and a large number of tests made in different sections of the state show this to be very low in vitality. Very little of it is fit to plant without first being carefully tested.
Most farmers who had seed for sale have already sold out their surplus, so the bulk of the corn planted this year on Iowa farms will have to be saved from the corn grown upon the farm the past season. The only way that ears from this crop fit for seed can be secures is by use of the individual ear germination test.
