HYBRID FIELD CORN VARIETY TEST RESULTS FROM
THE EVERGLADES AGRICULTURAL AREA, SPRING, 1980

Kenneth D. Shuler and C. G. Chamblis 1

Field corn continues to be grown in the Everglades Agricu\lgr~' A (EAA)
as a spring crop in rotation with sugarcane and vegetab s. tn 1979 over 6,700
acres of field corn were grown in the EAA, 90% for high moisture ora rAdIa
1980 more than 10,700 acres were grown. A survey of ove irs eht
vealed that Golden Harvest 2775 and Dekalb XL 78 were th-t ommonly used
varieties. This report includes the results of a test conducted in the spring of
1980 involving 35 field corn hybrids.

Experimental Procedure

The test was conducted in Palm Beach County on the A. Duda & Sons farm at
Belle Glade. The test was planted on Pahokee muck; 8.5 miles southeast of Lake
Okeechobee. The preceding crop was sugarcane and the soil test levels before
fertilization were as follows: pH 6.6, phosphorus 3, and potassium 34 (Belle
Glade AREC analytical procedures). The experimental design was a randomized
complete block with four replications of 35 different varieties. Plots consisted
of three 34-inch wide rows, 21 feet long, with data taken from one row. The test
was planted on February 22 and 23, 1980, and harvested June 25-27 (123 to 126 days
after planting). All plots were planted and harvested by hand. Plots were thinned
to 29 plants per row (21,231 plants per acre) four weeks after planting. Wireworm
damage contributed to reduced stands in some plots. Rainfall from planting until
harvest as recorded at the Belle Glade AREC was 15.6 inches, average minimum daily
temperature, 63.3 F; average daily solar radiation, 490.8 langleys.
Cultural practices were conducted by A. Duda & Sons. Production materials
used were as follows:
Fertilizer 1500 pounds per acre of 0-18-30 with micronutrients broadcast
dry. Techmagam (75-78% manganous sulfate) applied in 10 applica-
tions at 1 pound per acre and 1 application at 2 pounds per acre
(tank mixed with insecticides).

Herbicides Atrazine 80W and 11-E oil, 1 pounds and 1 quart per acre,
respectively applied post emerge.
Insecticides 2% parathion on corn glutin, 1 application at 40 pounds per
acre for wireworms applied preplant.

Insecticides con't

Por fall armyworm and corn earworm control:

Parathion 6-3, 1 application at 1 pint per acre,
Toxaphene 8-E, 3 applications at 1 pint per acre.
Lannate 2-L, 7 applications at pint per acre,

Fungicides Manzate 200, 1 application at 1 pound per acre.,

Results

Grain yields in bushels per acre, corrected to 15.5 percent moisture, are
presented in Table 1. Yields ranged from 62 to 143 bushels per acre. Data for
several other traits that may be of interest in selecting a corn hybrid are also
presented in Tablel.
