Summer Annual Grasses: -.L L of Florida

The summer annual grass variety trial contained five millets, seventeen
sorghum X sudangrass hybrids, one sudangrass, and one grain sorghum in 1980.
These were planted on April 17, 1980 in rows spaced three feet apart at a seeding
rate of 10 pounds per acre (11.2 kg/ha) on an Orangeburg loamy sand (Typic Paleudult).
The soil on which this trial was planted tested high in phosphorus; therefore, the
preplant fertilizer application was 125 pounds per acre (140 kg/ha) of 60% muriate
of potash. An application of 300 pounds per acre (336 kg/ha) of ammonium nitrate
was made on May 5, and additional applications at 100 pounds per acre (112 kg/ha)
were made on June 3, July 7, and August 5. Harvests were obtained on June 2, July
2, August 4, September 9, and October 13. Parts of this growing season were
extremely hot and dry, and the yields for a few varieties, particularly Gahi-3
millet, are surprisingly good in view of the prevailing weather conditions. It
should also be noted that the soil on which this trial was planted was probably
the driest ever used here for a summer annual grass variety trial. Data for this
trial are presented in tables 1, 2, 3, and 4.

Forage Sorghum and Corn for Silage:

The silage trial contained thirteen forage sorghums and three varieties of
corn. This trial was planted on April 17, 1980 on an Orangeburg loamy sand. Sorghum
was seeded at 10 pounds per acre (11.2 kg/ha) and corn was planted at 40 grains
per row and later thinned to 22 plants per row. Rows were sixteen feet long and
spaced three feet apart (4.9 m X 0.9 m). Prior to planting, an application of
125 pounds per acre (140 kg/ha) of 60% muriate of potash was disked into the soil.
Phosphorus was at a high level according to soil tests. An application of 300
pounds per acre (336 kg/ha) of ammonium nitrate was made on May 5. Herbicides
used were atrazine at one pound per acre (1.12 k,/ha) and propachlor at four
pounds per acre (4.5 kg/ha). These were applied on April 18. A severe drouth occurred
in 1980, and the soil upon which the trial was located was extremely dry. The first
harvest began on July 29 and continued over a long period as different varieties
became ready. An application of 100 pounds per acre (112 kg/ha) of ammonium nitrate
was made on August 27. The second harvest began on October 27 and continued as
varieties became ready until November 18 when all were harvested just prior to a
temperature drop to near freezing. Data for this trial are presented in tables
5, 6, 7, and 8.

Perennial Grasses:

This trial is located on a Red Bay fine sandy loam soil (Rhodic Paleudult).
The grasses were established in 1978. An application of 300 pounds per acre (336
kg/ha) of an 8-24-24 fertilizer was made on March 27, 1980. Ammonium nitrate at
100 pounds per acre (112 kg/ha) was applied on April 30 and on August 12. The rate
was 200 pounds per acre (224 kg/ha) on July 9 for ammonium nitrate. Harvests were
made on April 29, May 30, July 8, August 7, and September 8. Data on yield and
protein content are presented in tables 9 and 10.

Perennial Legumes:

A trial containing several perennial legumes was planted October 17, 1979 on a
Dothan fine sandy loam soil (Plinthic Paleudult); Red clover and birdsfoot trefoil
were seeded at 10 pounds per acre (11.2 kg/ha), and white Clover was seeded at 6
pounds per acre (6.7 kg/ha). Prior to plaiting, an application of 400 pounds per
acre (448 kg/ha) of an 0-36-15 fertilizer was disked into the soil. Comnerdial
inoculants were used at planting. Harvests were obtained oh February 29, April
10, April 30, May 28, July 1, and August 1. Data are presented in table Ill The
data through May were previously published in Jay, ARC Research Report WF80-3.

Precipitation:

Rainfall data obtained in 1980 at the Agricultural Research Center, Jay are
presented in table 12. Heavy spring rainfall delayed plantings, and high temperatures
along with lower rainfall brought on a severe sumner drouth. The monthly precipita-
tion figures do not indicate the severity of the drouth in early June and July
because of the way the rainfall was distributed. There was practically no rainfall
during the first eighteen days of June while 2.81 inches (7.14 cm) was recorded for
June 22. From June 28 until July 17 only 0.01 inches (0.03 cm) of rain fell. The
year, as a whole, actually closely approached the 32-year average, but the distri-
bution was generally quite unfavorable to crop production,

Grain Sorghum:

Cultivars of 39 grain sorghums were tested in replicated trials in 1980 on an
Orangeburg loamy sand to determine yield, maturity, disease resistance, and combine
height. All cultivars were planted April 21 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 apart. A preplant application of 125 pounds per acre (140 kg/ha) of 60%
muriate of potash was disked into the soil and 300 pounds per acre (336 kg/ha)
ammonium nitrate was applied May 5. A pre-emergence application of 1 nound aatrex
and 4 pounds propachlor (1.12 and 4.5 kg/ha, respectively) controlled weedy grasses
and broadleaves. Soil insect and nematode control consisted of 20 pounds per acre
(22.4 kg/ha) Furadan applied in a band six inches deep under the row before plant-
ing and 20 pounds per acre (22.4 kg/ha) Heptachlor applied broadcast over the row at
emergence.

First harvest was made July 24. Grain harvest from the ratoon crop was not
made.

Parts of the 1980 growing season were extremely hot and dry and yields of all
cultivars, in general, were poor. Considering the season, however, the yields
might be considered good. Data on yield, height, maturity, and disease are present-
ed in table 13. Two- and three-year averages of yield of several cultivars grown
at the ARC, Jay are presented in table 14.
