Planting Dates Higher corn grain yields will be obtained with early plantings. In most regions this means seeding between the last week of April and May 15. Early planting is recommended because risk of fall frost damage is greater with each day planting is delayed. The risk increases rapidly after May 20 and seeding corn for grain production is not recommended after June 1. Select and plant early-maturing, short-season hybrids when planting is delayed because of wet, cold planting conditions. Date of planting studies have been conducted at Oakes, Casselton and Fargo, ND. In these studies approximately one bushel per day was lost by delay of planting during the month of May. For silage corn, later plantings can be tolerated without great yield losses but can result in frosted corn, thus lowering quality of forage. Back to Planting
