• This project compares yields of
fall brassica crops following a
spring cover crop of oats and
peas. In treatment plots spring
cover was grazed by sheep; control
plots were un-grazed.
• There were no statistical differences
in brassica yield by treatment (grazed vs. un-grazed
• Though Black had more than 3
tons DM/ac of aboveground biomass,
the sheep trampled more
than they foraged because the
oats were too fibrous.
• Black is interested in grazing
more spring-seeded cover crops
based on trial results; Quee plans
to stay with his current system of
grazing in fallow years and in the
early spring and late fall.

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.
• Imperial had the highest yields at four
of six farms, followed by Gypsy and
• At three farms, Imperial had statistically
higher yields than the other
• 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.

Growing tomatoes in the high tunnel gives farmers an early jump on the tomato market, and can help protect the plants from some environmental stressors. Two farmers (Tim Landgraf at One Step at a Time Gardens and Mark Quee at Scattergood Friends School) conducted replicated variety trials in high tunnels of two determinate tomato varieties, Mountain […]

Two farms conducted replicated
variety trials in high tunnels of two determinate
tomato varieties, Mountain
Fresh Plus and Rebelski.
• Yield at both farms was lower than
yields reported in other published high
tunnel variety trials.
• Rebelski yield was higher at Landgraf’s,
with 1.4 lb/plant difference.
• Rebelski yield was also higher at
Quee’s, with 2.1 lb/plant difference.

• This project tested the effect on
over-wintered garlic yield of planting
date and two mulching strategies:
companion-seeded oat cover crop vs.
• Farmer-cooperator Mark Quee planted
garlic in September with a companion
oat cover crop (oat residue following
winterkill intended to serve as mulch).
Garlic planted in October was mulched
• September-planted garlic had higher
yield than October-planted, but pervasive
rot in several areas of the field
may have impacted results.

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

Registration is now open for the 2016 Practical Farmers CSA Workshop Retreat, February 5 – 6, at the Pilgrim Heights Retreat Center in Montour. Attendees will be divided into an “Experienced” group (at least three years experience managing a CSA) and an “Exploratory” group (those in their first years or new to CSA management).

Five farmers compared two bell pepper varieties, Olympus and Revolution, to determine which produces better in Iowa’s climate. Each farm planted four randomized pairs of research plots, each pair with 10-20 plants of each variety.

• Each farm planted four randomized
pairs of research plots, each pair with
10-20 plants of each variety.
• Pepper yield was significantly different
by farm, but treatment (variety) also
had a significant effect on yield. Revolution
yield was significantly higher
than Olympus when all farms were
• Revolution produced more pounds
and number of peppers per ft2 and
per plant than Olympus at three of
five farms. The remaining two farms
saw no difference in yield between the
• Average plant yield of green bell peppers
across all farms was 4.3 lb/plant
for Revolution and 4.03 lb/plant for
• Plant spacing was different by farm,
but end-of-season yield for green bell
peppers ranged from 1.82 – 2.66 lb/ft2.
