The 2017 PDMP/Penn State silage hybrid testing program included 200 hybrids and 20 companies and we were able to generate data for hybrid performance evaluations we believe producers will find useful when making purchasing decisions this year.
The plot locations are chosen within 4 growing zones. Maturities across these zones range from 85 to 118 days relative maturity. We strive to conduct our tests in unbiased methods using state of the art techniques and appreciate the support of the seed companies and farm cooperators to accomplish this each year.

New Starch Digestibility Data This Year!
This year, we have added Ash, Fat (Total Fatty Acids), NDFD30hr (previously 24hr), NDFD120hr, and NDFD240hr to data spreadsheets.
Starch digestibility data will be available at a later date at 4 locations. This starch digestibility test differs from the "Starch" column in the report. The Starch % will still be posted, but an additional column labeled "IVSD" (In-Vitro Starch Digestibility) will signify starch digestibility. This test is performed using wet chemistry, instead of NIR, run at a 4 hr incubation period at a 1 mm grind.
