and dried cash crop biomass were
collected to observe the cash
crop response to clover and soil
management treatments.
Field results highlights
In 2022, clover biomass remained
consistent throughout the season in
squash fields until the end of season
when clover died due to drought
throughout the season. Broccoli
clover biomass, however, increased
throughout the season, and weed
biomass decreased, resulting in
strong clover populations moving
into winter. Yield reductions of
both broccoli and squash occurred
in the no-till plots due to heavy
competition with weeds and clover
in both locations.
In 2023, clover biomass remained
consistent throughout the season
for squash fields, due to poor clover
establishment early in the season.
The broccoli field clover biomass
increased throughout the season
and created a rich blanket of clover
by the end of the season to further
suppress weeds. Yield reductions
were present in the no-till plots due
to high weed populations for squash
and large clover populations for
broccoli. Due to a heat wave causing
puffiness and bolting in September,
only 29% of broccoli heads harvested
were considered marketable. Due
to the small size of some fruit,
66% of total squash harvested was
considered marketable.
Take-Home Message
Installation of plastic mulches
continues to be a priority for
vegetable farmers in the Midwest
to improve weed control and
reduce labor costs. Cover crops
incorporated as a living mulch into
farm systems may aid in weed
