• When frost-seeded in the spring,
cover crop growth appears to be
related to GDD accumulated prior
to termination.

Cover crop entries were hand seeded at
locations into standing corn and soybeans
and evaluated for fall ground cover,
spring ground cover, and spring biomass
production.
KEY FINDINGS
• Cereal rye and mustard tended to
produce the most amount of fall ground
cover.
• Sufficient rainfall following cover crop
seeding is necessary for fall cover crop
growth and overwintering potential.
• Cereal rye was the only entry to
successfully overwinter and produce
spring growth and remains a strong
cover crop candidate even in the face of
a challenging winter.
