SH-2 SWEET CORN CULTIVAR TR AL, X%5j^4Rg pRIDA/

M h .A.S. Univ. of Florida

Twenty three sh-2 sweet corn cultivars were planted March 17, 1984, in a
Lauderhill muck soil in Zellwood, Florida. Seeds were hand planted one kernel
per drop, nine inches apart. Three row plots, each row spaced three feet on
center and 25 feet long were replicated four times.

Prior to planting, 1200 pounds per acre of a 10-4-10 dry fertilizer were
broadcast and disked to incorporate. A 2% parathion bait was used for wireworm
control at a rate of 40 pounds material pet acre. Lasso plus Atrazine were
used after irrigation. Methomyl was applied nine times between silking and
harvest by airplane.

Plots were harvested as close to optimum maturity as possible. Each
cultivar was harvested once when the majority of ears were judged mature. Yield
data are presented in Table 1. Ear length and width (diameter) were measured
from a random sample of 10 husked ears per replication. Ear tip fill was
assigned a value of 5 when completely filled and a value of 1 if over 1 inch
of the tip was not filled. Due to heavy pressure from corn ear worms and sap
beetles, it is essential for Florida grown sweet corn to have good husk cover.
There were 7 cultivars in the top 15 which would be undesirable in Florida due
to poor husk cover ratings. The best overall cultivars in this test were
Summer Sweet 7800 (slightly large), FMX23, Sweet Time, and Florida Staysweet.

Seeds were obtained from:

AC Abbott and Cobb
AS Asgrow Seeds
FM Ferry, Morse
HA Harris Seeds
SU Sun Seeds
TW Twilley Seeds
