“This is amazing,” said Susan Jutz at the end of T.D.’s field day, as we loitered in his spacious and tidy machine shop. “He does so much… and he’s so young.” Indeed, this was T.D. Holub’s first field day with PFI, which he hosted with his fiance, Sarah Gericke, near Coggon at their Garden Oasis Farm. […]

In 2016, 76 farmer-researchers conducted 109 trials on farms across the state spanning the field crops, livestock, and horticulture program areas. On Dec. 8-9, 2016, 70 farmers gathered in Ames at the Cooperators’ Meeting to discuss completed on-farm research projects and design new experiments. The Cooperators’ Program is the epitome of what PFI is all about: […]

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.

According to Carmen Black, plant seedlings started in soil blocks […]

In a Nutshell
• This was an informal trial to compare
bell pepper production from
seedlings started in soil blocks vs.
plug trays.
• Data were collected from 72 plants
in each treatment; peppers were
harvested at green and red stages.
Key Findings
• Though statistical analysis was not
possible, pepper plants started in
soil blocks had higher yield and
number of green and red peppers
per plant and fewer cull fruit.
