What is the temperature range for optimal corn germination?

The optimal temperature range for corn germination is critical for ensuring effective seed sprouting and establishment of healthy plants. The range between 50°F to 86°F is considered ideal for corn because at these temperatures, enzymatic activities necessary for germination occur efficiently. Soil temperatures below this range can slow or inhibit the germination process, leading to poor establishment and increased susceptibility to diseases. Conversely, while higher temperatures within this range can promote quicker germination, temperatures above 86°F may also induce stress conditions or negatively impact seedling vigor. Therefore, the specified range best aligns with the physiological needs of corn seeds during germination.
