In a Nutshell
• Six farmers compared three broccoli
varieties, Belstar, Gypsy and Imperial,
to determine which produces better
during summer months (harvest July –
Sept.) in Iowa.
Key Findings
• Imperial had the highest yields at four
of six farms, followed by Gypsy and
Belstar.
• At three farms, Imperial had statistically
higher yields than the other
varieties.
• Plant spacing differed by farm, but
average yield per area was 0.28 lb/ft2
for Imperial, followed by Gypsy (0.27
lb/ ft2), and Belstar (0.22 lb/ft2)
• Following the indications of the data,
most farmers strongly preferred Imperial
as their summer broccoli variety.

RESEARCH REPORT

In a Nutshell
• Fifteen farms participated in fruit and
vegetable production recordkeeping
to date.
• The purpose of the project was to
create Iowa-specific production
histories for:
• producers to have baseline
comparisons,
• the advancement of crop
insurance options,
• and to provide information about
typical Iowa production for
lenders.
• Actual yields exceeded FSA-NAP
yield estimates for most crop
categories.

RESEARCH PROTOCOL

Fruit and vegetable farmers use mulch
to control weed competition plus
increase moisture retention for cash
crops.
• Many fruit and vegetable farmers
use plastic mulch but concerns about
its environmental sustainability have
farmers wanting to test other mulch
types.
KEY FINDINGS
• 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
plots.
• 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.

RESEARCH REPORT

Worm castings, or vermicompost,
are a common addition to potting
soil mix and greenhouse bedding,
and are recommended for use with
nearly any plant
• Castings can be added at seeding or
transplant, used to side-dress during
the growing season, incorporated to
compost piles or vegetable beds, or
steeped as a compost tea and added
during watering or as a foliar spray
• The objectives of this project were to
determine whether casting additions
or application method increased
yield of fall cabbage.
• While differences are seen with other
plants in the literature, no differences
were seen here
