Variety Trials of Summer Annal Gra s o age Sd h and
Corn for Silage, Perennial. Grasses, and in Sor um

L. S. Dunavin and H. A-.-Peacock!

Summer Annual Grasses.

Twenty-four varieties of summer annual grasses were tested in 1979 to deter-
mine their forage production potential. These were planted on March 28, 1979 in
rows on a three-foot spacing at a seeding rate of 10 pounds per acre (11.2 kg/ha) on
a Red Bay fine sandy loam soil (Rhodic Paleudult). Prior to planting, an application
of 400 pounds per acre (448 kg/ha) of 8-24-24 was disked into the soil. An applica-
tion of ammonium nitrate at 300 pounds per acre (336 kg/ha) was made on May 3 with
additional application's at 100 pounds per acre (112 kg/ha) on June 29 and on August
20. Five harvests were obtained and data are presented in Tables 1-4.

Silage Trial.

Fifteen varieties of sorghum and three varieties of corn were included in the
silage variety trial. These were planted on March 28, 1979 in rows on a three-foot
spacing at a seeding rate of 10 pounds per acre (11.2 kg/ha) for sorghum. Corn was
planted at 40 grains per 16-foot (4.9 m) row and later thinned to 22 plants per row.
The soil was a Red Bay fine sandy loam (Rhodic Paleudult). Prior to planting, an
application of 400 pounds per acre (448 kg/ha) of 8-24-24 was disked into the soil.
A side-dressing of 300 pounds per acre (336 kg/ha) of ammonium nitrate was applied
on May 3, 1979. Pre-emergent herbicides were Propachlor at 4 pounds per acre (4.5
kg/ha) and Atrazine at one pound per acre (1.12 kg/ha). The first harvest began on
July 9, 1979 and was completed on July 23. Rain as well as varietal maturity diff-
erences caused the long time span. A side-dressing of 200 pounds per acre of ammonium
nitrate was applied on August 20, 1979; however, 911 was not side-dressed at that
time because it had not yet headed nor been harvested. The second harvest began on
October 31 and was completed on November 15 following a minimum temperature of 360
F. the previous night. Data are presented in Tables 5-8.

Perennial Grasses.

Seven varieties of bermudagrass and two limpograsses (Hemarthria altissima)
were established in 1978 on a Red Bay fine sandy loam soil (Rhodic Paleudult). On
March 16, 1979 an application of 450 pounds per acre (504 kg/ha) of an 8-24-24
fertilizer was applied. Applications of ammonium nitrate at 100 pounds per acre
(112 kg/ha) were made on April 27, June 8, and August 21. Five harvests were
obtained. Data are presented in Table 9.

Grain Sorghum.

Cultivars of 43 grain sorghums were tested in replicated trials in 1979 to
determine yield, bird depredation, lodging, and days to bloom. All cultivars were
planted March 28 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 pre-plant

application of 400 pounds (448 kg/ha) 8-24-24 per acre was disked into the soil
(Red Bay fine sandy loam) on March 20 followed by a side-dress application of 300
pounds per acre (336 kg/ha) ammonium nitrate on April 16. A pre-emergence applica-
tion of 1 pound Aatrex + 4 pounds Bexton ai per acre (1.12 + 4.48 kg/ha) on March
29 controlled weedy grasses and broadleaves except morningglory. 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 on March 26 and 20 pounds per acre (22.4
kg/ha) Heptachlor applied broadcast over the row on April 4.

First harvest was made July 26. Grain harvest from the ratoon crop was not
made because of bird depredation. Data on yield, height, bloom date, and bird
damage are presented in Table 10. Two- and three year averages of yield of several
cultivars grown at the ARC, Jay are presented in table 11.

Monthly precipitation data are presented in Table 12.
