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
