What temperature range is generally optimal for corn germination?

The optimal temperature range for corn germination is 50 to 86°F. Within this range, the seeds can absorb moisture effectively and activate the necessary enzymes that initiate the germination process. The temperature encourages the metabolic activities that transform the stored energy in the seed into the energy needed for growth.

At temperatures below 50°F, germination can be significantly delayed, and poor seedling vigor may result. Conversely, temperatures exceeding 86°F can lead to unfavorable conditions, such as excessive metabolic activity that can harm the seed.

Understanding this temperature range is crucial for farmers and agronomists to ensure successful planting and maximize yield potential for corn crops. Proper management of planting time relative to soil temperature can significantly improve germination rates and early plant growth.
