UT Variety Testing Program Research on Corn Grain and Corn Silage

Dr. Virginia R. Sykes, Variety Testing Coordinator and Agroecology Extension Specialist at the UTK Department of Plant Sciences, leads the UT Variety Testing Program. This program works to provide essential data to help Tennessee farmers choose the best hybrids to aid in boosting the sustainability of their farming systems. Sykes and her team evaluate, analyze, and publish trials identifying corn hybrids that are regionally adapted, high-yielding, and disease/insect resistant. Through this research, our state's corn growers can improve land use efficiency and reduce inputs like pesticides, herbicides, and water.

Not only does the program provide ecological benefits, but it has a direct economic impact on Tennessee agriculture. Over the past three years, corn hybrids tested through the UT Variety Testing Program have yielded an average additional 8 bushels per acre, translating to an estimated $43 million in added annual revenue across the state. This dual benefit allows farmers to improve sustainability and maximize profitability while reducing the environmental footprint of corn farming.

This database will offer detailed information on hybrid performance across different regions of Tennessee, helping growers make better-informed seed purchase decisions that align with their specific needs.
