Everglades Station Mimeo Report EES69-18 May 1969

1965 Field Corn Research
f- ----~"EVerghd Wl'Area

Victor E. Green, Jr.-


Almost every year since the Station was established, corn trials have been
conducted in a quest to: .find new, improved varieties and hybrids that are better
than those which have been previously: grown.

Experimental

Four field corn variety tests were conducted during 1965, on old muck,
contiguous to one another. Test 1 consisted of 3 Rocamex and 5 Poey hybrids of
the 60- and 70-series, compared with Mayorbela and Big Joe. Test 2 contained
10 tropical varieties previously tested at this Station. Test 3 was largely a
test of old and new Funk hybrids of the G-(Southern) series, along with Rocamex
H-504 and Cade CS 274. Test 4 contained 2 Poey old white hybrids, a repeat of
the Table 1 entries of Poey hybrids of the 70- series, and 4 new Funk hybrids
to check their adaptability to March planting. There were 10 entries in each
test. The experimental design was the randomized complete block with 6 replica-
tions in each test. Plots consisted of one row of corn 20 feet long with rows
3 feet apart running east and west. All rows and experiments were bordered.
Ten-foot alleys separated replications and experiments. The survival stand
goal was 1 plant every foot, or 14,520 plants per acre. Seed were planted on
February 17, except in Test 4 on March 10, every 12 inches in rows 3 feet apart
and the stand thinned to one plant per foot.

Land preparation consisted of a mid-December plowing, disking in late
December, and disking and levelling in early January. Mole drains were run
from the south ditch every 12 feet at a depth of 3 feet in mid-January. On
January 21, 3-12-12 fertilizer was applied at the rate of 500 lbs./A. and con-
tained 1% each of CuO, MnO, B203, and ZnO, with 5 lbs./A. technical Aldrin for
wireworm control. Pre-emergence application of CDAA and CDEC (Vegedex and Ran-
dox) were made on February 19, except Test 4 on March 12, under the supervision
of Dr. J. R. Orsenigo, Weed Scientist at this Station. Slight frost damage was
experienced on February 27. Weed control was adequate to harvest. Skips in
the stand were replanted for Test 1 on March 5; Test 2 and 3 on March 8; and
Test 4 on March 19. On April 1, budworms were controlled by spraying 2 qts.
DDT 25% and pint of 8E Toxaphene in 100 gallons of water per acre. The plots
were cultivated lightly on March 29 and April 2, and laid-by on April 5. The

pollen midpoint was recorded for each variety in each replication on the date
of occurrence. On May 27, each plot was rated for resistance to northern leaf
blight. Stalk heights and ear heights above the ground were recorded on June 4.
Percentage stands and percentage lodging were recorded on July 12. The plots
were harvested as snapped corn on July 13. Tests 1 and 2 were weighed in the
husk on July 16 and Tests 3 and 4 were weighed on July 20. The ears in each
sack were husked and the earcorn weights were taken. Six-ear samples were used
to determine shelling percentage, test weight and moisture at harvest.

RESULTS

The data summarizing the test are shown in Tables 1 through 8. The data
for varieties occurring in more than one test are shown in Table 9. The cumu-
lative yields of varieties and hybrids grown thrice or more times at this Station
in February plantings are shown in Table 10.

Test 1. Big Joe, a multi-lined synthetic variety released at this Station in the
1940's was the earliest of the group, and along with Mayorbela, its female par-
ent, the lowest yielding. Poey T-78 and Rocamex H-501 both yielded almost 100
Bu./A. The Rocamex hybrids were the tallest with the highest set ears from the
soil level. Poey T-72 stood best against winds and wet soil conditions. There
was little or no difference among the entries regarding resistance to leaf
blight.

Test 2. Poey T-62 and second generation Rocamex H-501 yielded about 90 Bu./A.
each. Corneli 54 and Poey T-62 were most resistant to leaf blight. Rocamex
hybrids were the tallest with the highest set ears, and were among the last to
shed pollen.

Test 3. Funk G-4703, a single cross, was the earliest pollinator of the corns
in the 3 tests planted February 17, and along with Funk G-745 and G-711AA,
lodged most. Cade CS 274 yielded 95 bushels per acre, while Rocamex H-504 gave
the highest yields of the 3 tests, 105 Bu./A.

Test 4. This is the late-planted test. The 4 new Funk G-series entries were
disappointing. Poey T-23A, a special cross yielded 95 bushels per acre. The
4 Poey T-hybrids grown both in Test 1 and in this test showed interesting com-
parisons. All 4 in this late-planted test grew taller, had higher-set ears,
lower leaf blight ratings, and made better stands. Three of the 4 had lower
yields when planted in March.
