VARIETY TRIALS OF WARM-SEASON PERENNIAL GRASSES,
SUMMER ANNUAL GRASSES, GAMAGRASS, AND GRAIN SORGHUM

L. S. Dunavin, H. A. Peacock, 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 1995. The bahiagrasses, rhodesgrass,
and Suerte atra paspalum 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 application of 400
pounds per acre of an 8-24-24 fertilizer was made 14 March 95. Ammonium nitrate
was applied to supply 35 pounds per acre N on 04 May 95 and 50 pounds per acre N
on 08 June, 11 July, 10 Aug., 06 Sept., and 28 Sept. 95. Harvests were obtained
on 01 May, 05 June, 07 July, 02 Aug., 31 Aug., 26 Sept., and 26 Oct. 95. Yields
of dry matter are given in Table 3 and show Tifton 18 bahiagrass to have the
highest average yield at 13,390 pounds per acre; however, this was not significant-
ly higher than the yield for Tifton 9.

Warm-Season Perennial Grasses and Crabgrass.
This trial contained old plots of Florakirk bermudagrass and Tifton 9 bahiagrass
which had been established for a number of years. It also included plots of Red
River crabgrass and plots overseeded with Red River. Florakirk was set in the late
summer of 1986 and Tifton 9 was planted on 17 May 88. Red River was planted on 14
April 95. Red River was seeded on prepared seedbeds at 10 pounds of seed per acre
and in the double-seed treatment at 20 pounds of seed per acre. Red River was also
overseeded on Florakirk plots and on plots which contained crabgrass in 1994 at 10
pounds of seed per acre. The soil was a Red Bay sandy loam (Rhodic Paleudult). An
application of 300 pounds per acre of an 8-24-24 was made on 10 April 95. Ammonium
nitrate was applied at 200 pounds per acre on 06 June and 07 July 95 and at 100
pounds per acre on 17 Aug. 95. Yield .data are presented in Table 4,and show the
highest production of dry matter to be from Tifton 9 bahiagrass at 10,710 pounds
per acre. Florakirk was not very productive in 1995 because the nine-year-old stand
has deteriorated to a considerable extent. The crabgrass just did not do well under
the conditions of this trial.

Summer Annual Grasses.
Twenty entries of summer annual grasses were tested in 1995. This trial was located
on a Dothan fine sandy loam soil (Plinthic Paleudult). Planting was done on 19 May
95. This was considerably later than we usually plant. Prior to planting, an applica-
tion of 400 pounds per acre of 8-24-24 fertilizer was made on 02 May 95. Ammonium
nitrate was applied at 200 pounds per acre on 06 June and 18 Aug. 95 and at 100.pounds
per acre on 07 July 95. The first harvest was made with the plants not as tall as
usual and the second harvest was made within 3 weeks. Four harvests were obtained.
Tift Exp. 5 millet produced the highest average yield of dry matter (9,410 pounds
per acre); however, the yield was not significantly higher than that of Tift. Exp.
4 millet. Yield data are given in Table 5.

Gamagrass.
Observations were made on three ecotypes and a cultivar of Eastern Gamagrass.
These observations were made on single plants set on four-foot centers. The
plants were set on 29 Mar. 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 Agr. Exp. 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 18 May 95, and 200 pounds per acre of
ammonium nitrate were applied on 10 July 95. Only three harvests were obtained
in 1995. These were on 15 May, 10 July, and 24 Aug.. The highest yield was
obtained from the Alabama ecotype at 14,230 pounds per acre. Yield data are
presented in Table 6.

Grain Sorghum Jay.
Cultivars of 48 grain sorghum hybrids and one grain millet were planted in a
replicated trial at WFREC, Jay in 1995 on a Tifton sandy loam to determine yield,
heading data, head type, disease reaction, lodging, height, and bird depredation.
All hybrids were planted 20 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 250 Ibs./A 8-24-24 was disked into the soil and 300 lbs./A ammonium
nitrate was applied as a topdressing on 08 June. A preemergence application of 1
lb. atrazine and 4 lbs. propachlor/A controlled weedy grasses and broadleaves
except morningglory. Preciptation by day of month at WFREC, Jay is shown in
Table 7.

On 03 August, hurricane "Erin" flattened the grain sorghum planting and no harvest
of grain was possible.

Grain Sorghum Marianna.
Two plantings of 40 grain sorghum hybrids were made at NFREC, Marianna, in 1995
on a Chipola loamy sand. The early planting was made 14 April and a late planting
was made in June. The June planting was not harvested because of hurricane "Opal"
damage. The April planting was fertilized preplant with 400 Ibs./A 18-9-8,
sidedressed with 300 lbs./A 13-13-13, and sidedressed with 250 Ibs./A ammonium
nitrate. The April planting was irrigated 7 times for a total of 7" of water.
Precipitation for NFREC, Marianna is shown in Table 8. Data on yield and other
agronomic characteristics from the April planting are shown in Table 9. The
highest yielding hybrid was DeKalb DK-58 with 6,353 Ibs. grain followed by DeKalb
DK-54 with 5,826 lbs./A grain. The mean yield of the test was 4,370 Ibs./A.

Yields from the April planting at NFREC, Marianna in 1993, 1994, 1995, and two-
and three-year average yields are presented in Table 10. The highest yielding
hybrid averaged over two years was DeKalb DK-54 followed by Hyperformer 1330DR
and DeKalb DK-55. The highest yielding hybrid averaged over three years was DeKalb
DK-58 followed by Agri Pro HSC Wings.

Table 11 lists the sources of seed for the 1995 grain sorghum and annual forage
tests grown at WFREC, Jay and NFREC, Marianna.
