Variety Trials of Summer Annual Grasses, Sorghum and.'A ernfdo0Sr'T ge,
Alfalfa, Red Clover, White Clover, and rain Sorghum

L. S. Dunavin, H. A. Peacock, and D. Gorbet

Summer Annual Grasses:
The summer annual grass trial contained five millets and fifteen sorghum X
sudangrass hybrids in 1985. These were planted on April 4, 1985 in rows which were
sixteen feet long and spaced three feet apart. Three replications were used. The
seeding rate was ten pounds per acre. For the use of those who would like to con-
vert to metric units, the conversion factors are given in Table 1. This trial was
located on an Orangeburg sandy loam soil (Typic Paleudult). An application of 300
pounds per acre of an 8-24-24 fertilizer was applied and disked into the soil on
March 26, 1985. Ammonium nitrate was applied at 200 pounds per acre on May 14 and
at 100 pounds per acre on July 10 and August 14. The trial area was plowed on May
1. Harvests were made on May 31, July 3, August 1, and September 26. April was dry
with only 35% of the 37-year average precipitation (Table 2). May also was below
average in precipitation; however, June had 2.1 times as much rain as average and
July had 1.5 times as much as average with August also above average. Chinch bug
damage did not appear to be as severe as in 1984; however, Sevin was utilized on
June 13 and July 10 at recommended rates for chinch bug control. Yields were very
poor in 1985, and weather seemed to be the main reason for the poor yields; however,
Failure to control crabgrass and nutsedge had some effect also. Data for yield,
height, disease, and maturity are presented in Tables 3, 4, and 5.

Sorghum and Corn for Silage:
Seven forage sorghums, one sweet sorghum, two sorghum X sudangrass hybrids,
and six corns were evaluated for silage potential in 1985. This trial was planted
on April 15, 1985 in 5-row plots. Rows were sixteen feet long and spaced three
feet apart. Three replications were used in the trial. The seeding rate for sorghum
was 10 pounds per acre. Forty grains of corn were planted per row and later thinned
to 22 plants per row. A preplant application of 400 pounds per acre of 8-24-24
fertilizer was applied and disked into the soil. A side-dress application of
ammonium nitrate at 200 pounds per acre was applied on May 15 and again a few days
following the first harvest. The soil was an Orangeburg sandy loam (Typic Paleudult).
The corns were harvested on July 26, and most of the sorghums on July 31 with one
entry harvested on August 4 and the sweet sorghum, MN1500, harvested on August 20.
The second or ratoon harvest of sorghums was done on November 6 following a tempera-
ture of 350 F on the preceding night. At this harvest, many entries were relatively
immature. Data on yield, lodging, height, disease, and maturity are presented in
Tables 6, 7, and 8.

Alfalfa:
An alfalfa cultivar trial was planted on October 23, 1984 at AREC, Jay on an
Orangeburg sandy loam soil (Typic Paleudult). Prior to planting, two tons per acre

of dolomitic limestone were applied, disked into the soil, and turned under, and
another ton was applied and disked into the soil. This was done to bring the soil
pH near 7.0. An application of 600 pounds per acre of an 0-30-15 fertilizer was
applied on October 19. Solubor at 20 pounds per acre was applied on October 23 at
planting. The alfalfa was seeded at 20 pounds per acre and a commercial alfalfa
inoculant was used on the seed. The area was cultipacked following seeding. The
weather was dry at planting and soil conditions were not as favorable as desired.
There were generally fair stands on November 30. The extremely low 30 F experienc-
ed in late January did some damage but did not destroy the alfalfa. Harvests were
obtained on April 30, June 5, July 1, and August 28, 1985. An excessively wet
summer was partially responsible for the relatively low yields obtained (Table 9).
At an observation made in mid-October, 1985, stands were extremely poor.

Clover:
Due to loss of stand of fall-planted red and white clovers, a.spring planting
of these was made on March 27, 1985. The soil was an Orangeburg sandy loam (Typic
Paleudult) which had been well-limed and fertilized during the fall for the fall-
planted clovers which were destroyed by the cold weather of late January. Seeds
were inoculated with commercial inoculants and planted at 10 pounds per acre for
red clover and six pounds per acre for white clover. Harvests were obtained on July
1 and on August 28. Data are presented in Table 10.

Grain Sorghum Jay:
Cultivars of 65 grain sorghums were tested in a replicated trial in 1985 on a
Red Bay sandy loam (Rhodic Paleudult) to determine yield, height, lodging, heading
date, head type, and disease reaction. All cultivars were planted April 4 at a
seeding rate of 12 seed per foot of row [8 to 12 pounds seed 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 500 pounds per acre (560 kg/ha) of 8-24-24 fertilizer was disked into the soil
and 200 pounds per acre (224 kg/ha) ammonium nitrate was applied as a top dressing.
A preemergence application of 1 pound of atrazine and 4 pounds of propachlor (1.12
and 4.5 kg/ha, respectively) controlled weedy grasses and broadleaves except
nutsedge and morningglory. Soil insect control consisted of 20 pounds per acre
(22.4 kg/ha) Furadan applied in a band 6 inches (15.24 cm) deep under the row before
planting. Grain was harvested July 30 and dried to 12% moisture before weighing.

Yields were good for most cultivars but the final yields were only fair because
unfavorable weather conditions at and following grain maturity caused pre harvest
sprouting and shedding of the grain. Data on yield and other agronomic character-
istics are presented in Table 11. The highest yielding hybrids were Savanna 5
(Northrup King) with 6780 pounds grain per acre (7590 kg/ha), followed by NK2665
(Northrup King) with 5810 pounds grain per acre (6510 kg/ha), and DK64A (DeKalb)
and Gator Grain B (Florida Seed and Feed) with 5660 pounds grain per acre (6340
kg/ha). Several other hybrids yielded more than 5000 pounds grain per acre (5600
kg/ha), approximately 83 bushels per acre which is 21 bushels per acre more than
the average yield from 63 corn hybrids in unirrigated test plots in 1985. Two- and
three-year average yields of several hybrids grown at AREC, Jay are presented in
Table 12. The highest yielding hybrids averaged over three years was Savanna 5
(Northrup King). The highest yielding hybrid averaged over two years was also
Savanna 5 (Northrup King).

Leaf diseases were evident (primarily Anthracnose, Colletotrichum graminicola)
but were not as severe as observed in some years.

Grain Sorghum Marianna:
Two plantings of commercial grain sorghum hybrids were made at the AREC,
Marianna on April 12 and July 25. Both plantings were irrigated. Neither test
yielded as much as in previous years. The test planted in April needed more
nitrogen and the test planted in July suffered from midge damage and too much
water. The wet weather late in the season caused grain mold, grain sprouting in
the head, and severe Anthracnose. The two tests had 37 entries each. The April-
planted test was irrigated 3 times for a total of 3 additional acre-inches of
water. The July-planted test was irrigated 2 times for a total of 1.75 acre-
inches additional water.

Yield and other data from the April and July plantings are presented in
Tables 13 and 14, respectively. Three-year yields and 2- and 3-year average
yields are presented in Table 15. Rainfall data for AREC, Marianna are presented
in Table 16.
