Variety Trials of Summer Annual Grasses, Sorghum and Ic_ EorJrt.ag ,Forida
Perennial Grasses and Grain Sorghum

L. S. Dunavin and H. A. Peacock1

Summer Annual Grasses:

The summer annual grass variety trial contained twenty-six entries in 1981.
These were planted on April 3 in rows spaced three feet (0.9 m) apart at-a seeding
rate of 10 pounds per acre (11.2 kg/ha) on a Dothan fine sandy loam soil (Plinthic
Paleudult). An application of 500 pounds per acre (560 kg/ha) of 8-24-24 fertilizer
was applied and disked into the soil prior to planting. An application of 300
pounds per acre (336 kg/ha) of ammonium nitrate was made on April 21 and additional
applications of 100 pounds per acre (112 kg/ha) on June 15, July 16, and August 14.
Harvests were made on May 18, June 10, July 7, Aug. 5, Sept. 3, and Oct. 5. Data
are presented in Tables 1-4, and average yield data for several recently tested
summer annual grasses are presented in Table 5.

Forage Sorghum and Corn for Silage:

The silage trial contained eight forage sorghum cultivars, the sweet sorghum
cultivar, Theis, at two rates of seeding, and two cultivars of corn. These were
planted on April 3, 1981. The seeding rate was 10 pounds per acre (11.2 kg/ha) for
the forage sorghums and 10 and 3 pounds for the cultivar, Theis. Corn was planted
at 40 grains per 16-foot (4.9 m) row and thinned in April to 22 stalks per row.
Prior to planting, an application of 500 pounds per acre (560 kg/ha) of 8-24-24
fertilizer was disked into the soil which was a Dothan fine sandy loam. An
application of 300 pounds per acre (336 kg/ha) of ammonium nitrate was made on
April 21 and an-application of 200: pounds per acre (224 -kg/ha) on July 22. Atrazine
was applied at 1.8 pounds per acre (2.0 kg/ha) active ingredient and an oil-surfac-
tant blend at one quart per acre on April 23 for weed control. The first harvest
began on July 14 when the forage sorghums and corn were harvested and ended on
July 22 when Theis was harvested. The second harvest began on 20 October and ended
on 6 November. Data are presented in Tables 6, 7, and 8.

Biomass and/or Forage Observation:

Six entries including Gahi-3 millet, FS-25a+ forage sorghum, 911 forage sorghum,
broomcorn, Sordan 79 sorghum X sudangrass, and Tifleaf-l millet were planted July 29,
1981 on a Dothan fine sandy loam in a non-replicated observation for determination
of biomass and/or forage. These were planted following corn. An application of 200
pounds per acre (224 kg/ha) of ammonium nitrate was made on August 28. The millets
were harvested on Oct. 20, FS-25a+ and Sordan 79 on Nov. 6, and 911 and broomcorn
on Nov. 20. Data are presented in Table 9.

Perennial Grasses:

Seven varieties of bermudagrass were set out in the spring of 1978 on a Red
Bay fine sandy loam soil (Rhodic Paleudult). One harvest was made in the fall of

1Associate Professor of Agronomy and Professor and Center Director, respectively.







1978 and five harvests each in 1979 and 1980. A single harvest was made on May. 5
81, and the trial was terminated. Plant material from some of the plots was used
to establish new pastures and other types of trials. The total yield data from
this trial are presented in Table 10.

Fifteen plots each of Tifton 44 bermudagrass and the limpograss introduction,
P.I.364888, were established in June, 1981 in preparation for a trial to begin in
1982. The soil was a Dothan fine sandy loam (Plinthic Paleudult) and had adequate
amounts of P and K at setting. An application of 100 pounds per acre (112 kg/ha)
of ammonium nitrate was made on 30 June 81. No other fertilizer was applied prior
to the single harvest made on 8 Sept. 81. The average yield of dry matter at this
harvest was 9,480 pounds per acre (10,620 kg/ha) for P.I.364888and 6,730 pounds
per acre (7,540 kg/ha) for Tifton 44. It should be noted that June and July had
only about half the normal rainfall; however, the precipitation in August was above
normal.

Llano buffelgrass was established in May, 1980 and harvested twice in 1980.
It is located on a Dothan fine sandy loam soil. Ammonium nitrate was applied in
1981 at the rate of 200 pounds per acre (224 kg/ha) on 29 May and 100 pounds per
acre (112 kg/ha) on 30 June and again on 6 August. Four harvests were made in 1981
and the following yields of oven dry forage were obtained (pounds per acre):
28 May = 1350, 30 June = 6150, 6 August = 3300, 4 September = 3030, Total = 13,830
(multiply by 1.12 to obtain kg/ha).

Climatological Data:

Climatological data recorded at the Agricultural Research Center, Jay are
presented in Table 11. The total rainfall for the year of 46.65 inches (118.49 cm)
indicates a drouth year. However, the distribution was such that most crop yields
were normal. Summer annual grasses, forage sorghum, corn, and grain sorghum yields
were higher than in 1980. The summer was hot but drouth periods did not last more
than two weeks and crop yields approached normal levels.

Grain Sorghum:

Cultivars of 43 grain sorghums were tested in replicated trials in 1981 on a
Red Bay sandy loam (Rhodic Paleudult) to determine yield, disease resistance, head
type, and combine height. All cultivars were planted April 15 at a seeding rate of
12 seed per foot of row [8 to 12 pounds per acre (8.9 to 13.4 kg/ha) depending on
seed size] in rows 3 feet (0.9 m) apart. A preplant application of 250 pounds per
acre (280 kg/ha) of 8-24-24 was disked into the soil and 300 pounds per acre (336
kg/ha) ammonium nitrate was applied May 1. A preemergence application of 1 pound
atrazine and 4 pounds propachlor (1.12 and 4.5 kg/ha, respectively) controlled
weedy grasses and all broadleaves except morningglory. Soil insect control consisted
of 20 pounds per acre (22.4 kg/ha) Furadan applied in a band six inches (15.24 cm)
deep under the row before planting and 20 pounds per acre (22.4 kg/ha) Heptachlor
applied broadcast over the row at emergence.

First harvest was made July 21. Grain harvest from the ratoon crop was not
made because of damage by sorghum midge and birds.

In spite of hot and dry periods during the growing season, yields of most cul-
tivars were about normal. Data on yield, head type, height, and disease are presented
in Table 12. The highest yielding cultivar was Two 64-YG (Texas Triumph). Several
cultivars, Gator Grain, C-228Y, Dr-1053, GK-522G, and G-611 yielded more than 7,000
pounds grain per acre (7,840 kg/ha), approximately 117 bushels per acre. Two- three-
and four-year average yields of several cultivars grown at the ARC, Jay are presented
in Table 13.
