West Florida

Research' and Education Center


The Jay lleacarch and Education Center (Jay
REC), part oftlhe University of Florida's Institute of
Food and Agricultural Sciences (WrAS), is about 15
miles. south ofJ.y and aloult 1.I miles north of
Mlilton, 3.I1/2 inil.~ we.t or Florida 39 and 3.1/2 miles
east or Florida 197 on Florida 182 in the heart or
Sntln lIn.n County's fanrmlnnd. The Iteseanrch Center
con.istL nrnn office building, a soils Inlmralory. a
ncnlatolohy laboratory, a fornae &rnp laboratory. and
a \eed Science Inboratory along with 24 support
building.'. The Center is located on 640 acres with
about 1f0 acres in pine trees. 40 acres in roads and
building nite. and *100 acres in cultivation. Thel Jny
Ihecnarch and Edlucntion 'was nauthorized in Chapter
2 19)87. Act. or 19.3,. by the State l.egislatlure. ,nil
-1I0 acres ofcut-over tilmberlnnd was purchased front
Fnnridn Pulp and Paper Compnny in 10-17.

Because of the distance between the extreme weat.
crn part of Florida and the Florida Agricultural Ex*
periment Station in Cainesvillo, relatively little was
known about the soils, the fertility requircmentL of
crops. and crop adaptations for the soils and climante
in this part of Florida. Through experimentation con-
ducted from n mobile unit from the North Florida Ex.
periment SLntion at Quincy. the farmers were .alown
som: or the aoricilturnl potential of thia area and
this. very likely, was responsible for the cdmnnnd by
farmers and buainessmen of the four wc.stcrnmnast
Florida counties for a branch station in thli area. The
tirst experimental ploLs were planted in 19-18.

Variety Trials of Several Warm-Season Grasses, Clover, Corn, and Grain Sorghum

L. S. Dunavin, H. A. Peacock, and D. W. Gorbett


Conversion factors are given in Table 1 for the use of those who would like to
convert to metric units. Climatological data are presented in Table 2.

Warm-Season Perennial Grasses.
Twelve grasses were included in this trial in 1996. The bahiagrasses, rhodes-
grass, and Suerte atrapaspalum were planted on 22 April 92, and rooted plants
of all others except Tifton 85 and Coastal bermudagrass were set on 23 April
92. Tifton 85 was set on 14 April 93 and Coastal was set on 18 April 94. The
trial was located on an Orangeburg sandy loam (Typic Paleudult). An applica-
tion of 400 pounds per acre of an 8-24-24 fertilizer was made on 13 March 96.
Ammonium nitrate was applied to supply 50 pounds per acre N on 15 May, 13
June, 11 July, 7 Aug., and 10 Sept. 96. Gypsum was applied at 125 pounds per
acre on 26 April 96. Harvests were obtained on 14 May, 11 June, 10 July, 7
Aug., 6 Sept., and 4 Oct. 96. Yields of dry matter are given in Table 3. The
cold temperatures in the first week of February, 1996 severely damaged Callide
rhodesgrass and Suerte atra paspalum. Whether the damage and succeeding poor
yield of limpograss was due to the cold or to numerous harvests in 1995 or a
combination of the two or something else is not known at this time.

Gamagrass.
Observations were made on three ecotypes and a cultivar of Eastern gamagrass.
These observations were made on single plants (replicated 4 times) set on
four-foot centers. The plants were set on 29 March 93. They had developed
into relatively large plants. The ecotypes were from Alabama, Tennessee, and
Florida (Ona-2). The cultivar was 'Pete' which was released in 1988 by the
USDA-SCS in cooperation with the Kansas and Oklahoma Agricultural Experiment
Stations and the USDA-ARS. The plants were located on an Orangeburg sandy loam
soil (Typic Paleudult). An application of 400 pounds per acre of an 8-24-24
fertilizer was made on 24 May 96. Ammonium nitrate was applied at 100 pounds
per acre on 3 July and 7 Aug. 96. Harvests were obtained on 22 May, 1 July,
29 July, and 20 Sept. 96. The-Ala. entry had significantly higher season
yields than Pete and Tenn. Data are presented in Table 4.

Russell bermudagrass.
Observations were made in 1996 in a trial containing Russell bermudagrass and
Tifton 85 bermudagrass which were set in 1995 and Florakirk bermudagrass which
was set in 1996 and Carostan flaccidgrass and Red River crabgrass which were
planted 22 Apr. at 10 pounds of seed per acre. Also included in the trial was
an entry of volunteer grasses which was to a large extent broadleaf signal-
grass. Russell and Tifton 85 were set on 16 May 95 and Florakirk was set on
4 April 96. An application of 400 pounds per acre of an 8-24-24 fertilizer
was made on 26 April 96 along with 125 pounds per acre of gypsum. Ammonium
nitrate was applied at 200 pounds per acre on 13 June 96 and at 100 pounds per

acre on 3 July, 7 Aug., and 3 Sept. 96. Harvests were obtained on 4 June
(Russell and Tifton 85 only), 2 July (all except Carostan), 2 Aug., 26 Aug.,
and 24 Sept. 96. Data are presented in Table 5 and show the higher yielding
ability of Tifton 85 with Russell being better than the rest in 1996.

Suerte atra paspalum Carostan flaccidgrass and Red River crabgrass.
A trial was started in 1996 with the original intention of a fertility study on
Suerte atra paspalum, Carostan flaccidgrass, and Red River crabgrass. Stands
were not good enough to proceed as a fertility trial; however, the trial was
continued as a variety trial utilizing the averages of all plots of each
species in a particular replication. Plots were planted on 24 April 96 at
10 pounds of seed per acre on an Orangeburg sandy loam soil. Fertilizer
included 300 pounds per acre of 8-24-24 in April and 200 pounds per acre of
ammonium nitrate on 7 Aug. 96. More nitrogen should have been applied earlier,
but the future of the trial remained in doubt because of poor stands until I
decided to harvest it in August. Harvests were made on 5 Aug. and 11 Sept. 96.
On 5 Aug., Carostan was in early bloom and Red River was in full bloom. Data
for yield are given in Table 6.

Clover (Summer Residual Yields).
Data are reported in Jay, WFREC Res. Rept. WF96-5 Table 5 for 8 clovers during
the 1995-1996 season. A statement was made in the narrative section of that
report that additional harvests would be included in a later report. An
additional harvest was made on 16 July 96 and was certainly a warm-season
harvest. Only two of the clovers produced at this time. The yields were:
Cherokee red clover, 1100 pounds per acre of dry matter and Yuchi arrowleaf
clover, 310 pounds per acre of dry matter.

Temperate corn;
Cultivars of 23 corn hybrids were planted in a replicated trial in 1996 on an
Orangeburg fine sandy loam to determine yield, ear quality, and lodging. All
hybrids were planted 4 April at a seeding rate of 2 seeds per foot of row in
rows 3 feet apart. A preplant application of 600 lbs/A 3-9-18 was disked into
the soil and 300 lbs/A ammonium nitrate was applied as a topdressing 8 May.
Other normal farming practices were applied to the experimental area.

May was extremely dry (0.64 inches rainfall) and rainfall in June was only a
little more than one-half the 48-year average, Even so, 3 entries yielded more
than 100 bushels of grain per acre (Table 7). Agra Tech 888 was highest yield-
ing with 118 bu/A grain.

Two-, three-, and four-year average yields of corn hybrids grown at WFREC, Jay
are presented in Table 8. The highest yielding hybrid averaged over two years
was Agra Tech 888; over three years was Agra Tech 888; and over four years was
Northrup King N8811.

Grain Sorghum Jay:
Cultivars of 41 grain sorghum hybrids were planted in a replicated trial in 1996
on an Orangeburg fine sandy loam to determine yield, heading date, head type,
disease reaction, lodging, height, and bird depredation. All hybrids were
planted 4 April at a seeding rate of 10 seed per foot of row (8-12 lbs. seed/A
depending on seed size) in rows 3 feet apart. A preplant application of 500 Ibs/A
3-9-18 was disked into the soil and 200 lbs/A ammonium nitrate was applied as a


- 3-









topdressing on 8 May. A preemergence application of 1 lb. atrazine and 4 Ibs.
propachlor/A controlled weedy grasses and broadleaves except morningglory.
Grain was harvested 30 July and dried to 12% moisture before weighing. Pre-
cipitation at WFREC, Jay is shown in Table 9.

Yields were good for most hybrids with a test average of 8,253 Ibs/A grain
(Table 10). The lowest yield in the test was 4,598 Ibs/A grain. Rainfall
was 20.78" from 4 April through 30 July. The 48-year average for the same
time period at WFREC, Jay is 24.70". On average, in 1996, grain sorghum
hybrids yielded 49 bu/A more than average corn grain-yield.

There was no lodging or bird depredation in 1996. Leaf diseases were less
severe than in recent years (primarily Anthracnose, Colletotrichum graminicola).
There also was no preharvest seed sprouting.

Data on yield and other agronomic characteristics are presented in Table 10.
The highest yielding hybrid in the test was HyPerformer AP9850 followed closely
by Northrup King Savanna 5. Twenty-two of the 41 grain sorghum hybrids produced
more than 140 bu/A grain (8,325 Ibs/A).

Two-, three-, four-, and five-year average yields of hybrids grown at WFREC,
Jay are presented in Table 11. The highest yielding hybrid averaged over two
years was Northrup King Savanna 5 followed by HyPerformer HSC Wings and My-
cogen 444E; over three years was Triumph Two 80D; over four years was Triumph
Two 80D; and over five years was DeKalb DK-54.

Grain Sorghum Marianna:
Two plantings of grain sorghum were made at NFREC, Marianna in 1996 on Chipola
loamy sand. The early planting of 41 hybrids was made 18 April. The late plant-
ing of the same 41 hybrids was made 10 July. The April planting was irrigated 8
times for a total of 5.7" water and the July planting was irrigated 6 times for
a total of 4.4". Data on yield and other agronomic characteristics from the
April planting are presented in Table 12. The highest yielding hybrid was
DeKalb DK-54 with 7,248 lbs/A grain followed by Northrup King KS-936 with 6,964
lbs/A grain. The mean yield of the test was 5,477 lbs/A grain.

Data on yield and other agronomic characteristics of the July planting are pre-
sented in Table 13. The highest yielding hybrid was DeKalb DK-54 followed by
Northrup King KS-936. The mean yield of the test was 1,641 lbs/A grain.

Data from the April plantings at NFREC, Marianna and WFREC, Jay and the 2-loca-
tion average yields are presented in Table 14. The highest yielding hybrid from
the average of the two locations was Northrup King Savanna 5 followed by DeKalb
DK-54 and HyPerformer HSC Wings. The overall mean yield for the two test loca-
tions was 6,865 Ibs/A grain.

Table 15 lists the sources of seed for the 1995 grain sorghum tests grown at
WFREC, Jay and NFREC, Marianna.
