1977 Fall Sweet Corn Variety Trial
Zellwood, Florida

J. M. White


Sixteen sweet corn varieties were evaluated in replicated trials in an Ever-
glades mucky peat soil in Zellwood in the fall of 1977. Seeds were hand planted,
one kernel per drop, nine inches apart on August 26. Plots were two rows, each
three feet wide and 25 feet long. Prior to planting, 600 lb/acre of a 5-5-8
fertilizer was broadcast and disked to incorporate. A 2% parathion bait was used
for wireworm control at the rate of 40 pounds material per acre. A 50-50 mixture
of Randox and Vegadex at the rate of three pounds material (3+3 Randox and Vegadex)
per acre was applied to control weeds. Twenty applications of insecticide and 13
applications of fungicide were used to control insects and diseases on a preventative
basis. Minimal disease and insects were noted. A side application of a 5-5-8
fertilizer at 600 lb/acre was applied and incorporated by cultivation when the corn
was about two feet tall.

Plots were harvested as close to optimum maturity as possible. Each variety
was harvested once when the majority of ears were considered ready. The first
harvest was on October 28 and the last on November 4. Ears were counted and
weighed with the husk on. Ear length and width (diameter) measurements were taken
from a random sample of 10 husked ears per replication. Ear tip fill was assigned
a value of five when completely filled and a value of 1, if over one inch of the
tip was not filled. A value of less than 2.5 would be questionable for commercial
fresh market.

Seeds were obtained from the following sources: HUME LIBRAPY

Bonanza has been the leading fall variety grown in the Zellwood area. In this
trial, eight of the 16 lines yielded as well as Bonanza or better, but there were
no significant differences in the yield (doz/acre) of Bonanza and any other variety.
From the results of this one trial, several other varieties should be looked at as
potential fall varieties. An overall rating was given (Table 1) to estimate the
varieties potential usefulness as a fresh market fall variety. Seven varieties
rated well enough (4-5) to be tried on a limited basis. Jubilee, Golden Queen, LM-11,
Tendertreat EH, Pagent, 2583, Gold Cup, and 74-3164 were rated low, mostly on the
basis of poor ear tip fill, husk cover, and/or ear size. 74-3164 was considered too
large. LM-11 was on the long side and also too thin (narrow width). Tendertreat EH
and Jubilee had better flavor than most, but ear tip fill and husk cover were not
good. They would have received good ratings as processing lines, but not as fresh
market varieties.

J. M. White .

Twenty-two sweet corn varieties were evaluated in rep icated trials in an
Everglades mucky peat soil in Zellwood in the fall of 1978. S]e.:'d6.wJpha. a p; pl ,
one kernel per drop, nine inches apart on August 15. Plots weri~'t -rows-,eacn ...
three feet wide, and 20 feet long. Prior to planting, 600 Ib/acre of a 5-5-8
fertilizer was broadcast and disked to incorporate. A 2% parathion bait was used
for wireworm control at the rate of 40 lb material per acre. A 50-50 mixture of
Randox and Vegadex at the rate of three lb material (3+3 Randox and Vegadex) per
acre was applied to control weeds. Twenty appliations of insecticides were used
to control insects on a preventative basis. No fungicides were applied in order
to evaluate resistance to Helminthosporium (leaf blight). A side application of a
5-5-8 fertilizer at 600 lb/acre was applied and incorporated by cultivation when
the corn was about two feet tall.

Plots were harvested as close to optimum maturity as possible. Each variety
as harvested once when the majority of ears were considered ready. The first
harvest was on October 16 and the last on October 24. Ears were counted and
weighed with the husk on. Ear length and width (diameter) measurements were taken
from a random sample of 10 husked ears per replication. Ear tip fill was assigned
a value of five when completely filled and a value of 1, if over one inch of the

fresh market.

Bonanza has been the leading fall variety grown in the Zellwood area. In
this trial, 11 of the 22 lines yielded as well as Bonanza or better with nine lines
having significantly higher yield as measured by dozen ears per acre. In comparing
yield, the % stand should be considered. Some plots of Goldenrod, NCX 2009, and
Silver Queen had extensive racoon damage. The planting was made earlier this year
than last, as a result, the stand was poorer, incidence of disease greater, and
worm damage greater than experienced with later plantings.

A summary of the data is found in Table 1.
