Step-by-step explanation:
Planting date has a significant impact on corn yield when all other factors are equal. Research across the land grant system shows that there is an “ideal" planting window that exists, with a decline in yield with each additional day as less light and growing degree days are available to the plant. Of course that “ideal" time each year may vary due to the weather in that given year. Under ideal conditions, optimum planting dates range from April 15th to May 1st in the southeastern corner of the state to May 15th to 25th in the northern tier and Laurel Highlands.
