The prospect of delayed planting of corn leads corn growers to consider whether changes in seeding rate should be made in response to late planting. Discover the optimum plant populations based on planting date, according to Purdue University.

Good rainfall and warm temperatures in July and August are probably the most important factors that determine yield, says an Ohio State University Extension agronomist.

Avoid planting when the soil is wet, consider alternatives to applying nitrogen pre-plant and use the optimal seeding rate to see better results with late-planted corn.

Past Ohio State University research indicates that optimal plant populations for early (mid to late April) and late-planted (late May to early June) corn are similar.
