Variety Trials of Summer Annual Grasses, Sorghum
and Corn for Silage, and Grain Sorghum

Summer Annual Grasses: 1
The summer annual grass trial contained fo millets and fourteen sorghum X
sudangrass hybrids. These were planted on March 26, 19$,nrwaln which e re six-
teen feet long and spaced three feet apart. Thr e replications were use The
seeding rate was 10 pounds per acre. For the us o 1k to con-
vert to metric units, the conversion factors ar a blj 4rial was
located on an Orangeburg sandy loam soil (Typic Paleudult). An application of
250 pounds per acre of an 8-24-24 fertilizer was applied and disked into the
soil on March 15. Ammonium nitrate was applied at 200 pounds per acre on May 2
and at 100 pounds per acre on June 13 and on July 13. Harvests were made on June
5, July 11, Sept. 5, and Nov. 6. The weather was rather wet in August and prevent-
ed a harvest at that time (Table 2). Chinch bugs did severe damage to some of these
varieties and were particularly damaging to the millets. Sevin was utilized at
recommended rates on July 23 and again on Sept. 6; however, damage was very severe.
Data for yield, height, disease, and maturity are given in Tables 3, 4, and 5.

Sorghum and Corn for Silage:
Two sweet sorghums, ten forage sorghums, and four corns were evaluated for
silage potential in 1984. This trial was planted on April 6, 1984 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 seeded per row and later thinned to 22 plants per row. Pre-
plant fertilizer was an application of 500 pounds per acre of an 8-24-24 fertili-
zer on April 2. A side-dressing of 200 pounds per acre of ammonium nitrate was
applied on May 14 and another application at the same rate was made following the
first harvest. The soil was an Orangeburg sandy loam (.Typic Paleudult). An applica-
tion of 1.5 pounds per acre of atrazine and 1-1/2 quarts per acre of natural oil
was made on April 25 for weed control. The first harvest began on July 13 with the
varieties ready at that time and was completed on August 21 when MN1500 was har-
vested. The ratoon harvest began on October 10 and was completed on November 14.
Data are presented in tables 6, 7, and 8.

Grain Sorghum Jay:
Cultivars of 69 grain sorghums were tested in replicated trials in 1984 on a
Red Bay sandy loam (Rhodic Paleudult) to determine yield, height, lodging, head
type, heading date, and disease reaction. All cultivars were planted April 20 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 250 pounds per acre (280 kg/ha) ammonium nitrate was applied
May 10. A preemergence application of 1 pound of atrazine and 4 pounds of propa-
chlor (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 August 7 and dried to 12% moisture before
weighing.

Yields were good for most cultivars. Data on yield and other agronomic
characteristics are presented in Table 9. The highest yielding hybrids were Colt
(Asgrow) with 8230 pounds grain per acre (9220 kg/ha), 8303 (Pioneer) with 7740
pounds grain per acre (8670 kg/ha), Savanna 5 (Northrup King) with 7740 pounds
grain per acre (8670 kg/ha), and G-1711 (Funks) with 7740 pounds grain per acre
(8670 kg/ha). Several other hybrids yielded more than 7000 pounds grain per acre
(7840 kg/ha), approximately 117 bushels per acre. Two- and three-year average
yields of several hybrids grown at AREC, Jay are presented in Table 10. The
highest yielding hybrid averaged over three years was DK-64A (DeKalb). The highest
yielding hybrid averaged over two years was Savanna 5 (Northrup King).

A late season trial of 16 cultivars was planted July 26 on Orangeburg sandy
loam at the same seeding rate as that used in the April planting. A preplant
application of 500 pounds per acre (560 kg/ha) of 8-24-24 was disked into the
soil and the plants were top dressed with 100 pounds per acre (112 kg/ha) ammonium
nitrate. Grain was harvested after killing frost (harvested November 16) and dried
to 12% moisture before weighing. Data are presented in Table 11. Yields were good
with both ORO-XTRA (Young) and RA-787 (Ring Around) producing 4980 pounds per acre
grain (5580 kg/ha).

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

Grain Sorghum Marianna:
Two plantings of commercial grain sorghum hybrids were made at the Marianna
AREC on April 16 and July 24. Both plantings were irrigated but the July planting
suffered extensive moisture stress and drought damage before irrigations were be-
gun on September 12. The two tests had 68 and 73 entries, respectively. The April
test was irrigated four times and the July test was irrigated five times.

There were no insect problems on the April test but midge, chinch bugs, and
various head feeding worms were a problem on the July planting. Anthracnose was
somewhat of a problem on both tests but not as much on the late planting as often
occurs. The late season drought in September-November reduced yields directly on
the July planting and contributed to lodging on some entries, primarily due to
charcoal stalk rot (Macrophomina phaseoli).

Yield levels were near average, compared to previous tests, for both plantings.
Yield and other data from the April and July plantings are presented in Tables 12
and 13, respectively. Three-year yields and 3-year average yield are presented in
Table 14. Rainfall data for AREC, Marianna are presented in Table 15.
