Testing Results

This corn hybrid evaluation for silage production is a producer driven collaboration between the Professional Dairy Managers of Pennsylvania (PDMP) and Penn State.  Test plot locations are chosen within 4 growing zones, which are short, mid, . Maturities across these zones range from 85 to 118 days relative maturity.  Plots in 8 sites throughout the state were harvested for testing this year.  For convenience, results are accessible below in both Excel spreadsheet and PDF formats.  To watch our 2019 Corn Silage Discussion, link to the recorded webinar here.

NEW FOR 2020!

In 2019, an index called Organic Matter Digestibility (OMD) was added to the results. Only one location from each growing zone was used. In 2020, all locations were used. The OMD calculation is using wet chemistry to determine NDFD30 and 4-h starch digestibility.
