VARIETY TRIALS OF UPLAND COTTON

Hugh A. Peacock-/

We have grown a cotton variety trial at AREC, Jay for the last 14 years to
determine those varieties best adapted to this area and to provide a basis for
variety recommendations by the Extension Service. Variety trial results for 1993
and averages over several years are included in this report. Also included are
results from variety trials grown in Santa Rosa and Okaloosa counties, and AREC,
Jay; as well as variety trials grown in Tifton, Georgia; and Fairhope, Brewton,
Headland, and Monroeville, Alabama. From comparison of these reports, one should
be able to determine the cotton variety best adapted to a general area.

EXPLANATION OF DATA
\\
Harvest of Seed Cotton:
Tests at AREC, Jay, Santa Rosa, Fairhope, Brewton, Headland, Monroeville,
and Tifton, were harvested by a mechanical spindle picked. Average yield of seed
cotton was determined:for each variety at each location.

Lint Percentage:
Seed cotton samples from each variety were ginned on a 10-saw gin. Lint
percentage was calculated by dividing weight of lint by weight of unginned seed
cotton and multiplying by 100.

Lint Yield:
Lint yield was determined by multiplying seed cotton yield by lint percentage
for that variety. Lint yield from Florida tests was determined by multiplying seed
cotton yield by 0.40, an average lint percentage figure for this area.

Fiber Properties:

Length. For Alabama tests, this is the fiber length measured with the HVI
instrument and approximates classer"s staple. For Georgia tests, this is the
fiber length measured with the Digital Fibrograph. The 2.5% S.L. is the length in
inches and approximates classes'' staple; 50% S.L. is length in inches of the test
fiber specimen spanned by 50% of the fiber scanned. S.L. is span length.

Strength. A measure of the fiber strength of a bundle of fiber measured with
two jaws holding the fiber bundle separated by 1/8 inch, expressed in grams force
per tex. Tex is a size measurement of the fiber bundle expressed as the mass, in
millimeters, of 1 meter of the fiber filaments. The data are given as the force,
in grams, needed to break this bundle; also noted in Georgia data as T1. The
higher the number the stronger the fiber.

Elongation (El). A measure of the percentage stretch before the fibers break.

I/Professor and Center Director, University of Florida, Institute of Food and
Agricultural Sciences, AREC, Jay.

Micronaire. This measures the fineness of the cotton fibers taken from the
ginned lint. The smaller the micronaire reading, the finer and/or more immature
the fibers. The desirable range of micronaire is 3.5 to 4.9.

Uniformity. A measure of the uniformity of the fiber length of the fiber
sample.

Earliness. Where more than one harvest was made, earliness is reported as
the percentage of the total yield harvested at the first picking.

Fusarium Wilt. Reaction of varieties to Fusarium oxysporium f. vasinfectum
was evaluated under field conditions at the E. V. Smith Research Center at Shor-
ter, Alabama. These data are courtesy Kathy M. Glass, Research Assistant in
Agronomy and Soils, Auburn University, and Dr. W. S. Gazaway, Professor and
Extension Plant Pathologist/Nematologist, Auburn University, Auburn, AL.

RESULTS

AREC, Jay:
The AREC, Jay cotton variety test is a continuing evaluation of available
cotton varieties from private companies and state agricultural experiment sta-
tions. Breeding lines that are likely to be released are also tested. We try to
test only those varieties and strains that will be adapted to the North Florida-
South Georgia-South Alabama area. Cultural practices are those generally recommend-
ed by University of Florida to farmers. Every effort is made to test the varieties
and present the results in an unbiased manner. Appropriate analyses of the yield
data were made. The variability in the test was measured and is expressed as a
percentage of the test mean, that is, the coefficient of variation (CV). An indica-
tion of the magnitude. of difference between variety averages necessary to be
considered a real difference is given for each location and is designated as the
Least Significance difference (LSD05 and LSD01).

Thirty cotton varieties were tested in a single trial replicated four
times in 1993 on a Red Bay sandy loam to determine yield. All varieties were
planted May 6 at the rate of 20 lbs/acre acid delinted seed. A preplant
application of 250 lbs/acre 8-24-24 was disked into the soil along with Treflan
and Vernam. The stand was thinned to 3-4 plants/foot of row. Ammonium nitrate was
applied as a top-dressing at 200 lbs/acre plus 7 Ibs/acre nitrogen from urea two
times. The plots were harvested October 18. No supplemental water or potash was
applied. Pix was applied once.

Yields were good for most varieties. The overall mean for the test was 1212
lbs lint/acre. The data on yield at AREC, Jay in 1993 along with 2-, 3-, 4-, 5-,
and 6-year average yields are shown in Table 1. The highest yielding variety of
the varieties grown 3 years was Deltapine 51; the highest yielding variety of
varieties grown 6 years was Deltapine Acala 90.i Highest yield in 1993 was from
Stoneville 907.

Statewide Tests:
Data on yield of several cotton varieties grown at 3 locations in North
Florida are presented in Table 2. A test scheduled for Jackson County was never
planted because of unfavorable planting conditions. The highest yielding variety
from the 3-location average was Deltapine 51 followed closely by MD51ne. The
highest yielding variety from the two Santa Rosa locations average was Deltapine
51 followed by Deltapine 5415, MD51ne, and Deltapine 5690 (Table 2).

Sii' Table,3 presents data from cotton varieties grown at several locations in
both 1992 and 1993 and the 1992-1993 average yield of those varieties at Santa
Rosa county locations and all locations (including Santa Rosa county) where grown.
MD51ne was highest in both Santa Rosa county locations and in all locations for
the 2-year average yield.

New Strains Test:
Data on yield of several new strains grown in a test at AREC, Jay on Red Bay
sandy loam are presented in Table 4. Of the new cotton strains, Deltapine 5409 was
highest in yield followed by Suregrow 223, Seed Source 9302, Hyperformer 39, and
Suregrow 39. Yields were good with an overall mean of 1203 lbs lint/acre.

Georgia Tests:
Data on yield and other characteristics of cotton varieties grown at Tifton
(Tables 5, 6, 7, 8) are presented for your perusual. Of special interest might be
Table 8 which presents data on high quality (long and strong fibers with desirable
micronaire) varieties that might be grown in this area. Length, strength, and
fineness values for each variety in this test should be the values that could be
expected from those same varieties grown in North Florida. Yields would differ.

Yields in the variety trial at Tifton were good (Table 5) with the overall
mean of the test 1253 lbs/A lint. Highest yielding variety was Suregrow 125
followed by Suregrow 501. There was no significant difference in yield among the
first 7 entries.

The three-year average performance of cotton varieties grown at Tifton, GA is
shown in Table 6. Deltapine 51 was highest in yield followed closely by Deltapine
5415, Stoneville Georgia King, and Stoneville KC311.

The new strains test at Tifton CTable 71 shows yield and other characteristics
among the elite strains from breeders. Overall average yield was 1250 lbs/A lint.

The data presented in Table 8 are from high quality varieties grown at Tifton,
Acala 1517-88 should have the highest strength and longest fibers and may be used
as a check for length and strength of the other entries tested.

Climatological Data:
A summary of the climatological data for the Agricultural Research and Educa-
tion Center, Jay for 1993 is shown in Table 9 and the daily precipitation is shown
in Table 10. The AREC, Jay climatological gathering location is an official weather
station. The cotton tests at AREC, Jay- received 20.4 inches precipitation from
planting to harvest. No supplemental water was added.

Alabama Tests:
Data on yield and other characteristics of cotton varieties grown at Fairhope
in 1993 are presented in Table 11. The highest yielding variety was Suregrow 125
followed by-Stoneville 9573.

Data on yield and other characteristics of cotton varieties grown at Brewton
in 1993 are presented in Table 12. The highest yielding variety was Stoneville
9573 followed by Stoneville LA887.

Data on yield and other characteristics of cotton varieties grown at Monroe-
ville in 1993 are presented in Table 13. The highest yielding variety- was Deltapine
20. followed by Suregrow 404.

Data on yield and other characteristics of cotton varieties grown at Headland
in 1993 are presented in Table 14. The highest yielding variety was Deltapine 5690
followed by Suregrow 125.

The data in Table 15 presents average performance of cotton cultivars for
yield and other characteristics at South Alabama locations in 1993. Stoneville
9573 was the highest yielding entry when averaged over all South Alabama locations
followed closely by Suregrow 125, Deltapine DES119, and Suregrow 501.

The data in Table 16 presents two- and three-year average yield of cotton
cultivars grown at South Alabama locations. Suregrow 501 was highest in yield of
cultivars grown for two years at Fairhope, followed closely by Stoneville DES119
and Stoneville X84-828. Of cultivars grown three years at Fairhope, Deltapine 51
was highest in yield followed by Hyperformer HS46 and Deltapine 90. Stoneville
LA887 was highest in yield of cultivars grown two years at Brewton, followed
closely by Stoneville 907 and Deltapine 51. Of cultivars grown three years at
Brewton, Stoneville LA887 was highest followed by Deltapine 51 and Deltapine
DES119. Stoneville LA887 was highest in yield of cultivars grown for two years at
Monroeville, followed by Deltapine 20 and Deltapine DES119. Of cultivars grown
three years at Monroeville, Deltapine 5415 was highest followed by Deltapine
5690 and Deltapine DES119. Deltapine 5690 was highest in yield of cultivars
grown two years at Headland, followed closely by Chembred 1233 and Chembred 333.
Of cultivars grown three years at Headland, Deltapine 5690 was highest in yield
followed closely by Chembred 333, Suregrow 1001, Hyperformer HS46, and Deltapine
Acala 90.

Fusarium Wilt:
Data from the fusarium wilt test at the E. V. Smith Research Center, Shorter,
AL showing performance of commonly grown varieties are shown in Table 17. These
entries were grown on an Independence loamy fine sand highly infested with both
the fusarium wilt fungus (Fusarium oxysprium Schlect. f. vasinfectum [Atk.] Snyd.
and Hans.) and rootknot nematodes (Meloidogyne spp.). Plots were 40-inch-wide
bedded rows, 30 feet long, separated by 6-foot alleys. Four replications of the
test entries and checks, arranged in a block design, were evaluated. Both suscep-
tible (Rowden) and resistant (Auburn 56) cultivars were included as checks. Rowden
was planted in row 5 and every tenth row thereafter and Auburn 56 was planted in
row.10 and every tenth row thereafter throughout the test. Plots were planted May
7, 1993. Initial plant counts were made on June 2. Wilted plants were counted and
removed June 25, July 27, and August 24. The remaining live plants were also
counted and recorded August 24. Percent wilted plants was then determined and
mean wilting percentage for a given entry calculated.

The data in Table 18 is a summary of the data in Table 17. The wilt percent-
age of a particular variety in Table 18 should be interpreted in relationship to
the readings from the nearest susceptible and resistant checks.

Production Costs;
The estimated costs of producing an acre of cotton in North Florida and
break-even prices are presented in Table 19.

Recommended Varieties;
Varieties recommended by the University of Florida, IFAS, Florida Extension
Service that should yield well under normal conditions are as follows;

l/To get the best performance from Deltapine 90, care must be taken to prevent
excessive growth. A common error is to over-fertilize./, On the heavier soils
of Florida, N fertilization should not exceed 50 Ibs/A unless you have a
history of Deltapine 90 performance on the soil. If too much N is applied,
excessive plant growth and poor boll retention will result. In addition, lower
bolls will be more susceptible to boll-rotting organisms.
