2021 Corn Silage Test Reports Now Available

Nov 18, 2021

By Dwane Miller

For over 15 years the Professional Dairy Managers of Pennsylvania (PDMP) and Penn State have partnered in a corn silage hybrid testing program. The purpose of the testing program is to evaluate various corn hybrids for silage yield and other important agronomic characteristics. Results of the test can assist farmers in selecting hybrids best suited to their operation.

Beginning in 2019, a ranking tool known as the Organic Matter Digestibility Index (OMD Index) was used. This tool continues to be used through the 2021 testing for all locations, hybrids, and maturities. This data, as well as yield, digestibility, and other near infared parameters are measured.

In 2021, the silage trial locations encompassed 4 growing zones (short, mid-season, mid-season planted in late season locations, and late-season) across 8 counties. You can view the 2021 silage data on the Penn State Extension website. The corn grain data is still being tabulated and will be published to the same website in the near future.

Video: FCG Parvi Webinar 2: Getting to Know Thrips parvispinus to Better Control This Pest

This is the 2nd webinar in a 3-part series hosted by Flowers Canada Growers on Thrips parvispinus IPM. Biocontrol programs developed for western flower thrips do not appear to be effective against Thrips parvispinus. This webinar will examine what makes T. parvispinus different and how insights into its biology and behaviour—including chemical ecology, host plant preferences, and defensive responses—can help improve monitoring and management strategies. This webinar was recorded July 16, 2026. Guest speakers include: Jessie deHaan (Vineland Research), Dan Bath (Vineland Research), Laxmi Khadka (Vineland Research), Ashley Summerfield (Vineland Research), Sarah Jandricic (OMAFA), Avery Johnson (AAFC / University of Guelph).
