Sometimes questions arise concerning the length of time needed for corn to emerge. Following are a few of steps in that process of corn germination.

The first step in determining frost and freeze damage is to understand the temperatures at which damage occurs and how the extremes of temperature and duration can affect crops.

Blackleg resistance has been available in commercial canola varieties since the early 1990s. A shift towards increasingly virulent strains of the blackleg fungus has resulted in the breakdown of resistance in many traditional canola varieties. Increasing canola acreage and shortened rotations have contributed to this.

The decision to replant a field is one of the most difficult decisions a producer may face early in the growing season. Experience has shown that each year some of your acres will not achieve desired plant populations due to adverse environmental conditions. If you find yourself in a potential replant situation, there are several factors you need to take into consideration prior to replanting.

In addition to successful germination, successful emergence of corn seedlings is an important early step in successful stand establishment. The synchronization of coleoptile development and the cessation of mesocotyl elongation usually results in the appearance of the first leaf from the tip of the coleoptile just as the coleoptile breaks the soil surface.
