IX 3 Variety Trials of Summer Annual Grasses, Forage Sorghums for Silage,
Corn for Silage, Sunflowers, and Grain Sorghum

L. S. Dunavin and H. A. Peacock1

Trials were conducted in 1976 with several summer annual grasses to
determine their potential for grazing, hay or green chop. The trials were planted
on April 5, 1976 at a seeding rate of 10 pounds of seed per acre. Rows were on a
36" spacing. A pre-plant application of 400 pounds per acre of 8-24-24 was disked
into the soil. A side-dressing of 200 pounds per acre of ammonium nitrate was
applied on May 10. Additional applications of 100 pounds per acre of ammonium
nitrate were made on June 11 and on August 11. Sevin was applied on June 11,
August 3, and September 15 at two pounds per acre to control chinch bugs. Five
harvests were obtained and data are presented in Tables 1-5.

Eighteen varieties of forage sorghum were tested for silage potential in a
trial planted April 5, 1976. The seeding rate was 10 pounds of seed per acre in
rows on a 36" spacing. Prior to planting, an application of 400 pounds per acre
of 8-24-24 was disked into the soil. A side-dressing of 200 pounds per acre of
ammonium nitrate was applied on May 10. Immediately following planting, an
application of two pounds of Atrazine and 1-1/2 gallons of dinitro per acre was
sprayed onto the soil as a pre-emergence herbicide. The first harvest season
began on July 22 and was completed on August 4. An application of 200 pounds per
acre of ammonium nitrate was made on August 11. Sevin was applied at two pounds
per acre on September 15 and September 29 to control midge. The ratoon harvest was
made on November 5 and a killing frost followed. Data are presented in Tables 6,
7, and 8.

Nine varieties of corn were tested for value as silage in 1976. This trial
was planted on April 5, 1976 in rows on 36" spacing. Corn was planted at 30 grains
per 16-foot row and thinned in May to 22 plants per row. Prior to planting, 400
pounds per acre of 8-24-24 was disked into the soil. Immediately following
planting, the area was sprayed with two pounds of Atrazine and 1-1/2 gallons of
dinitro per acre as a pre-emergence herbicide. A side-dressing of 200 pounds per
acre of ammonium nitrate was applied on May 10. Harvesting began on August 3 when
the first variety had developed a black layer and was completed on August 10.
Data are presented in Table 9.

Twelve varieties of sunflower were tested for seed yield in 1976. These were
planted in rows on a 36" spacing on April 7. Forty seed were planted per 20-foot
row and the sunflowers were thinned to 25 plants per row in May. Prior to planting,
400 pounds per acre of 8-24-24 was disked into the soil. Also prior to planting,
one pound per acre of Treflan was applied and disked into t oil as a pre-plant
herbicide on April 6. The plants were side-d q o desseonds per acre of
ammonium nitrate on May 10. Seed were ar s on aanr data are present-
ed in Table 10.

Cultivars of 52 grain sorghuns were tested in replicated trials in 1976 to
determine yield, bird depredation, disease resistance, and lodging. In addition
25 hybrids were tested for the same characteristics, but especially for
resistance to the grain sorghum disease, Anthracnose (Colletotrichum graminicolum
(Ces) C. W. Wils). All cultivars were planted Iarch 30 at a seeding rate of 12
seed per foot of row (8 to 12 pounds per acre depending on seed size) in rows 3
feet apart. A pre-plant application of 400 pounds 8-24-24 was disked into the soil
on March 23 followed by a side-dress application of 300 Ibs. per acre ammonium
nitrate on April 14. A pre-emergence application of Atrazine at 2 pounds per acre
plus 6 quarts dinitro applied March 31 controlled weedy grasses and broadleaves
except cockleburs. Soil insect and nematode control consisted of 20 pounds per
acre Furadan applied in a band six inches deep under the row on March 25 and 20
pounds per acre Heptachlor applied broadcast over the row on April 2.

First harvest (Tables 11 and 12) was made July 21. Grain harvest from the
ratoon crop was not made because of bird depredation. Data on yield, head type,
height, disease rating, bird damage, lodging, and days to heading are presented
in Tables 11 and 12. Two- and three-year averages of yields of several cultivars
grown at the ARC, Jay are presented in Table 13.

Precipitation by months at the ARC, Jay in 1976 is presented in Table 14.

Jay, ARC Research Report WF77-4 / December, 1977

) -L Variety Trials of Summer Annual Grasse Forage Sog i /~.age,
Corn for Silage, Sunflowers and /ai Sorghum
6 1979
L. S. Dunavin and H /AI. Peacockl

Summer annual grasses were tested in 1977 to ii fp tential for
grazing, hay or green chop. This trial was planted on Aprt d seeding rate of
10 pounds per acre in rows spaced 3 feet apart. Prior to planting, 400 pounds per
acre of 8-24-24 were disked into the soil. A side-dressing of 400 pounds per acre
of ammonium nitrate was applied on May 3. Two additional applications of 100 pounds
per acre of ammonium nitrate were made on June 9 and on August 8. The very dry
weather in 1977 did not seriously affect yields. Six harvests were obtained and
data are presented in Tables 1-4.

The forage sorghum silage trial had eighteen entries in 1977. This trial was
planted on April 7 at a seeding rate of 10 pounds per acre in rows on a 3-foot
spacing. Prior to planting, 400 pounds per acre of 8-24-24 were disked into the
soil. Furadan 10 granules were applied in the furrow at 20 pounds per acre for
insect control. Immediately following planting, the area was sprayed with 2 pounds
of atrazine and 1-1/2 gallons of dinoseb per acre as pre-emergence herbicides. A
side-dressing of 400 pounds per acre of ammonium nitrate was applied on May 3. The
first varieties were ready for harvest on July 22 and harvest of the trial was
completed on August 5. An application of 200 pounds per acre of ammonium nitrate
was made on August 8. Although many varieties were immature, the ratoon harvest was
made on November 15 following several nights of low temperature. Data are presented
in Tables 5 and 6.

Ten varieties of corn were tested for silage potential in 1977. The trial was
planted on April 7 at 40 grains of corn per 16-foot row. Rows were on a 3-foot
spacing. The corn was thinned to 22 plants per row on May 10. Prior to planting,
400 pounds per acre of 8-24-24 were disked into the soil. Furadan 10 granules were
applied in the furrow at 20 pounds per acre to control insects. Immediately follow-
ing planting, 2 pounds of atrazine and 1-1/2 gallons of dinoseb per acre were
applied as pre-emergence herbicides. The corn was side-dressed on May 3 with 400
pounds per acre of ammonium nitrate. Corn was beginning to tassel on June 9, and
the weather was very dry (See Table 13). By June 15, lower leaves were firing badly
and it was obvious that the lack of moisture would severely reduce yield. Insects
were numerous and seemingly uncontrollable. Chinch bugs, earworms, and others were
exceedingly numerous despite sprayings (See Table 7). The trial was harvested on
July 20 with ears badly insect eaten and rotting. The best ear found in the whole
trial was from Coker variety 16 in replication 4. This ear was rotting on both ends
of the cob, worm eaten in the center, crooked, and, in most years, would be consider-
ed a real cull. The data, however, are presented in Table 7.

Six varieties of sunflower were tested in 1977. This trial was planted on
April 19 in rows on a 3-foot spacing. The sunflowers were planted at 40 seed per
16-foot row and thinned on May 10 to 22 plants per row. Prior to planting, 400
pounds per acre of 8-24-24 were disked into the soil. One pound per acre of 4EC
Treflan was disked into the soil for weed control. The sunflowers were side-dressed
on May 26 with 200 pounds per acre of ammonium nitrate. The sunflowers were irrigat-
ed several times during the severe drought. Seed were harvested on August 12.
Shattering was very severe prior to harvest and resulted in reduced yields. Data
are presented in Table 8.

-Associate Professor (Associate Agronomist) and Professor and Center Director,
respectively.





Cultivars of 54 grain sorghums were tested in replicated trials in 1977 to
determine yield, bird depredation, disease resistance, and lodging. In addition,
25 hybrids were tested for the same characteristics, but especially for resistance
to the grain sorghum disease, Anthracnose (Colletotrichum graminicolum (Ces) C. W.
Wils). All cultivars were planted April 4 at a seeding rate of 12 seed per foot of
row (8 to 12 pounds per acre depending on seed size) in rows 3 feet apart. A pre-
plant application of 400 pounds 8-24-24 per acre was disked into the soil on March
25 followed by a side-dress application of 400 pounds per acre ammonium nitrate on
May 3. A pre-emergence application of atrazine at 2 pounds per acre plus 6 quarts
of dinoseb applied April 5 controlled weedy grasses and broadleaves. Soil insect
and nematode control consisted of 20 pounds per acre Furadan 10 granules applied
in a hand six inches deep under the row on April 4 and 20 pounds per acre Heptachlor
applied broadcast over the row on April 8.

First harvest (Tables 9 and 10) was made July 27. Grain harvest from the
ratoon crop was not made because of loss of grain from bird depredation. Data on
yield, head type, height, disease rating, bird damage, lodging, and days to heading
are presented in Tables 9 and 10. Two-three-four-and five-year average yields of
several cultivars grown at ARC, Jay are presented in Tables 11 and 12.

In addition to Anthracnose, gray leaf spot (Cercospora sorghi Ell. and Ev.),
zonate leaf spot (Gleocercospora sorghi Bain and Edgerton), and sooty stripe
(Ramulispora sorphi Ell. and Ev.) were present but were of little economic impor-
tance. Dry weather affected yield to some extent, however, the effect was consider-
ably less than on corn.
