An earlier seeding date opens up
the opportunity for more diverse
cover crops like brassicas and
legumes that need more time and
heat units to grow than common
cover crops like cereal rye.
• Two farmer-cooperators
interseeded cover crops (cowpeas,
annual ryegrass, rapeseed) into
corn at the V4 stage in June. Corn
hybrids chosen exhibited vertical
and horizontal leaf orientations to
test whether more light penetrating
the corn canopy would encourage
successful cover crop establishment
and growth.
Key Findings
• Corn leaf orientation and corn
planting population did not appear
to have much of an effect on the
interseeded cover crops.
• Jack Boyer saw corn yields reduced
by an average of 24 bu/ac due to
the interseeded cover crops.

As farmers wrap up their season and plan for next, PFI’s farmer-cooperators have an additional responsibility: submit the data they collected from this year’s research trials and plan next year’s projects. The first week in December marks the annual two-day Cooperators’ Meeting where farmer members meet to discuss these research results with each other and […]

A roller-crimper presents farmers the opportunity to mechanically terminate cover crops without chemicals or tillage. This method is dependent on a large amount of cover crop growth and the cover crop reaching the flowering stage before crimping. A roller-crimper is a large, metal cylinder with “chevron” pattern blades that simultaneously lays the cover crop flat […]

Farmers reported that
in 59 of 63 site-years,
properly managed
cover crops had little to
no negative effect on
corn and soybean yield
(and actually increased
soybean yield in 8 siteyears
and corn yield in 2
site-years).
