In a Nutshell
• Delaying cover crop termination until
near soybean planting would allow
for more biomass production by the
cover crop in the spring presenting the
opportunity for more environmental
• Two farmer-cooperators continued
work they began in 2015 that compares
terminating a cereal rye cover crop 2-3
weeks prior to seeding soybeans (early
termination) with terminating the cover
crop within 5 days of seeding soybeans
• Jeremy Gustafson saw a 2 bu/ac increase
and improved weed control with
the late termination treatment in 2016.
This amounted to a $49.97/ac economic
benefit compared to the early termination
treatment. In 2015, soybean
yields were equivalent between the two
termination date treatments.
• Jack Boyer saw no difference in soybean
yields between the two cover
crop termination treatments in either
year. In 2015, he was able to skip a
post-emergence herbicide application
which saved him approx. $40/ac.

Objectives: 1. Determine if clover as a living cover has an effect on yield of cash crops in double-dug beds. 2. Evaluate effectiveness of clover as ground cover and weed control.

In a Nutshell
• Fruit and Vegetable farmers want to
use cover crops to control weeds,
which reduces labor costs and competition
with cash crops.
• In tilled plots, two-foot wide strips of
rye were incorporated prior to seeding.
In no-till plots, summer squash
was seeded into an overwintered
stand of cereal rye that was scythed at
• Squash yield (lb) and number of
squash produced were greater in tilled
plots than in no-till plots.
• Weeding the tilled plots took significantly
more time during the first
weeding of the season (July 8).
• Survival rate of seedlings was not different
between treatments on July 1,
but plant survival by Sept. 25 was 72%
in the till plots compared to 50% in the
• Average pounds of squash produced
per plant were not significantly different

Fruit and vegetable farmers use mulch
to control weed competition plus
increase moisture retention for cash
• Many fruit and vegetable farmers
use plastic mulch but concerns about
its environmental sustainability have
farmers wanting to test other mulch
• In 2012, both mulches reduced weeds
compared to bare ground and the
plastic mulch resulted in greatest
sweet potato yields.
• In 2013, watermelon production was
similar in the paper mulch and control
• In 2014, sweet potato production
trended higher in the plastic mulch
although not statistically greater.
The paper mulch and control were
similar again but the paper mulch was
shredded due to extreme weather
leaving little mulch.
