Managing for Delayed Corn Crop Development in 2009

Delayed planting and/or cool summer temperatures have delayed corn development in 2009. Consequently, crop maturity is expected to be delayed by two to three weeks in many areas. In northern states and areas with late-May and June-planted corn, freezing temperatures may occur before normal crop maturity. This Crop Insights discusses the possible impacts of cool temperatures and an early freeze on corn development, field drydown, yield, harvest, artificial drying and storing of grain.
