Hybrid Field Corn Variety Tests Results From The Everglades
Agricultural Area, 1981.

The 1981 field corn variety test was planted in a commercial

field of corn on Pioneer Farm No. 2 (Hundley Farms) 13 miles east

of Belle Glade, Florida. The soil was a Terra Ceia muck with the

following soil test values at planting time: pH-6.0, P-23, and

K-231 (Belle Glade-A.R.E.C. soil test procedures). The fertility

level was higher than that currently recommended for field corn.

No fertilizer was applied to the corn. Several crops of radishes

had been grown on this particular field prior to the corn crop.

The variety test was planted on March 10, 1981. The experimental

design was a randomized complete block with four replications of 30

different varieties. Plots consisted of three 36-inch wide rows,

S 22 feet long, with data taken from one row. Plots were laid out in

such a manner that only 20 feet of row:was planted leaving a 2 foot

space between the ends of plots. In this report the entire 22 feet

was used as a basis for calculating yields.' In previous reports 21

feet was used as the basis for calculating yields, which would give

slightly higher yields. The above statement is given to explain

+ the discrepancy between the report presented at the field day and

this report. Ranking of varieties remains the same.

Pesticides used for weed and insect control were as follows:

May 22 74 Toxaphene and Lannate 1 pint each

May 25 77 Toxaphene and Lannate 1 pint each

The field was cultivated twice for weed control.

The corn was harvested on July 13 and 14. Grain yields in

bushels per acre, corrected to 15.5 percent moisture, are presented

in Table 1. Yields ranged from 145 to 202 bushels per acre. Data

for several other traits that may be of interest in selecting a

corn hybrid are also presented in Table 1. Lodging and barrenness

were measured, but since neither were significant,results are not

reported.

The commercial field in which the variety test was located

was planted at 24,000 plants per acre with a final stand of 23,500

plants. It was estimated to have yielded 190 bushels per acre.

Two adjacent fields averaged approximately 171 bushels per acre.

It is felt that the unusually high yields for the varieties in this trial

as well as the commercial field were due in part to the 1) high soil fertility

levels, 2) increase in solar radiation, and 3) decrease in rainfall which

resulted in less lodging and stalk rot and a greater release of soil nitrogen.
