In a Nutshell
• Can frost-seeding small-seeded
brassica species into crop residue
be an effective spring cover crop
strategy?
Key Findings
• Among three locations, mustard
provided the most groundcover.
• When frost-seeded in the spring,
cover crop growth appears to be
related to GDD accumulated prior
to termination.

RESEARCH REPORT

In a Nutshell
• Cereal rye, oats and other
small grains grass species
have been proven as effective
cover crops in cornsoybean
systems in Iowa.
• Cooperators screened grass,
legume and brassica species
for fall and spring groundcover
in hand-seeded plots
(7.5’ x 25’) across the state.
Key findings
• Cereal rye remains the
most consistent cover crop
providing fall groundcover,
overwintering capability and
spring groundcover across
locations.
• Brassicas generally produced
as much fall ground cover
as the small grains grasses
in the present iteration of
the trial.
• Hairy vetch and radish
performed better than in
past iterations, likely due to
exceptional growing conditions

NEWS RELEASE

The latest iteration of PFI’s cover crop variety trial has been released: “Cover Crop Variety Trial, 2014-2015.” Cooperators evaluated 21 cover crop entries (pure stands and mixes) in small, hand-seeded plots across the state. See all the entries in the table below.

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.
