H. A. Peacockl/1"

We have grown a cotton variety trial at ARE Jay for the last 11 years to
determine those varieties best adapted fo. this area. Variety trial results for
1990 and averages over several years' ae' included in this report. Also included
are results from varietyiTrials grown in Santa Rosa, Okaloosa, Calhoun, and
Jackson Counties, and NFREC, Quincy in Gadsden County, as well as variety trials
grown in Brewton, Alabama.

Forty cotton varieties were tested in a single trial replicated 4 times in
1990 on a Red Bay sandy loam to determine yield. All varieties were planted 30
April 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 1 pint/acre Treflan.
The stand was thinned to 3-4 plants/foot of row. Ammonium nitrate was applied as
a top-dressing at 200 lbs/acre plus 14 lbs/acre Nitrogen from urea in two
applications. The plots were harvested 25 October. No supplemental potash or
water was applied. Climatological data for 1990 at AREC, Jay are shown in Table 1.

Yields were good for most varieties. The overall mean for the test was 935
lbs/acre. Data on yield at AREC, Jay in 1990 along with 2-, 3-, 4-, 5-, and 6-year
average yields are presented in Table 2. The highest yielding variety of the
varieties grown 3 years was Deltapine 90; the highest yielding variety of the
varieties grown 6 years was also Deltapine 90. To get the best performance from
Deltapine 90, care must be taken to prevent excessive growth. A common error is
to overfertilize. On the heavier soils in Florida, nitrogen application should not
exceed 50 lbs/acre, otherwise, excessive plant growth and poor fruiting will
result.

Data on yield of several cotton varieties grown at 7 locations in northwest
Florida are presented in Table 3. Note that the highest yielding variety planted
in all locations was a hybrid, Chembred 1135, followed by Stoneville 506 and
Deltapine 50.

Data on yield and other characteristics of cotton varieties grown at Brewton,
Alabama in 1990 are presented in Table 4. The highest yielding variety in 1990
was Deltapine 5690. The highest yielding variety of varieties grown 3 years was
HS46 followed by KC380 and Deltapine 90.

Data on yield and other characteristics of cotton varieties grown at Head-
land, Alabama in 1990 are presented in Table 5. The highest yielding variety in
1990 was Deltapine 51. The highest yielding variety of varieties grown 3 years
was KC380 followed by Deltapine 90 and Coker 84-828.

Data on yield and other characteristics of cotton varieties grown at Fair-
hope, Alabama in 1990 are presented in Table 6. The highest yielding variety in

1990 was DES119. The highest yielding variety of varieties grown 3 years was
Deltapine 90 followed by DES119 and HS46.

Data from the fusarium wilt test at Tallassee, Alabama showing performance
of commonly grown varieties are presented in Table 7. Rowden is the susceptible
check and S-35 is the resistant check.

The estimated costs of producing an acre of cotton in North Florida and
break-even prices are presented in Table 8.

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

*To get the best performance from Deltapine 90, care must be taken to prevent
excessive growth. A common error is to overfertilize. On the heavier soils, N
application should not exceed 50 lbs/acre unless you have previous history of
Deltapine performance on the soil. If too much N is applied, excessive plant
growth and poor fruiting will result.

If cotton follows soybean or. peanut, N fertilization should be limited to
30-50 lbs/acre to prevent excessive vegetative growth.
