UW Agronomy 2022 Report on Corn Research

Annual “Gold Book” Report on Cultural Practices and Management Systems for Corn in Wisconsin is now available

The Wisconsin Corn Agronomy program annually plants and harvests 12,000 to 13,000 plots at 14 locations in Wisconsin. Of these plots, about 3000 are harvested for forage with the remaining harvested for grain. Corn forage and/or grain yield, quality and other agronomic traits are measured on all plots.

Roughly half of the plots involve the Wisconsin Corn Hybrid Evaluation program, The best way to deliver technology to the farm-gate is through hybrids selected by farmers for various traits (i.e. pest resistance, lodging resistance, quality, etc.). Selecting adapted, high-performing hybrids often means the difference between profit and loss. Results of of this work are published every year in November and can be found here.

The other half of the program involves research on farmer management decisions. The results of this work are published every year in February and can be found here. Specific research objectives of this program focus on management decision-making regarding crop productivity, quality, and production efficiency including hybrid selection, rotation, tillage systems, and replant and yield loss damage assessments. Emphasis is on impacts of cropping practices on grower profitability, the environment, and natural resource conservation.

Below is a list of projects conducted during 2022.
