To determine if yield and profitability can be increased by applying various high-management practices in a high-population environment.

I encourage farmers to consider the agronomic characteristics of their hybrids when planning high management strategies including higher plant population, use of foliar nutrition, higher nitrogen rates with proper placement and timings, and a VT fungicide.

Corn hybrids vary in their adaptation to high-yield management practices. Ear type, disease resistance, and root structure play a significant role in response to higher population, VT fungicide, and foliar nutrition, respectively. Hybrids with less ear flex, like BECK 5829A4brand, usually respond favorably to higher plant populations. Hybrids with lower disease scores and/or corn after corn ratings, such as XL® 5665AMX™*brand and XL® 6158AM™*brand, usually respond favorably to a VT fungicide application. Hybrids with less root mass, like XL® 6158AM™*brand, may respond well to foliar nutrition. In 2016, XL® 6158AM™*brand responded the best to high management practices.
