Description
Weather in recent years has caused many corn seeding delays or replanting after a killing spring frost. Corn growers often inquire about how long it will take corn to reach maturity from a given growth stage. Iowa research results (Table 1) show how many calendar days or GDDs are needed for a typical hybrid to reach maturity from a given growth stage.
