Collard Variety Trial Results
Winter 2008-2009


By: Stephen M. Olson, Professor, North Florida Research and Education Center, Quincy,
Florida


Collards are a relatively minor crop in Florida but production occurs over most of the state
especially for local sales by small growers. Included in this trial are 2 new varieties. These
include 'Bulldog', a hybrid from Sakata Seeds and 'Ozark', an open pollinated variety from
University of Arkansas. 'Bulldog' is a fancy Georgia type and 'Ozark' is similar to 'Vates' and
was released for the processing industry. For a description of other varieties go to the following
EDIS document (http://edis.ifas.ufl.edu/HS353).

Eleven varieties were seeded on 29 Aug 2008. Seed were sown into number 200 flats (1.0 in x
1.0 in x 3 in). Varieties were transplanted into the production field on 10 Oct 2008. Soil type
was an Orangeburg loamy fine sand. Preplant fertilization was 70-70-70 lbs/A ofN-P2Os-K20.
In-row spacing was 12 inches and between row spacing was 3 feet. Goal 2XL at 2 pts/A was
applied on soil surface before transplanting. Nitrogen was applied twice during the season at 40
lbs N/A each time. Registered pesticides were applied as needed to control pests.

Plots were harvested on 14 Jan 2009. At day of harvest off-types were counted and only
marketable heads were included in yield. Yield is shown in Table 1. Highest yielding variety
was 'Bulldog' at 1671 25 lb crates/a but was not statistically different than 'Top Pick', 'Top
Bunch' and 'Flash'. Head size followed same pattern as yields. 'Morris Heading' and 'Georgia'
had more off-types than the other varieties. 'Ozark' produced yields and head size that were
equivalent to the other open-pollinated varieties.
