Variety Trials of Summer Annual Grasses, Forage Sorghums For
Silage, Corn For Silage, and Grain Sorghum=

L. S. Dunavin and H. A. Peacock1

Trials were conducted in 1975 with millets and sorghum X sudangrass hybrids
to determine their potential for grazing, hay, or green chop. The trials were
planted on March 28, 1975 at a seeding rate of 10 pounds of seed per acre. Rows
were on a 36-inch spacing. A pre-plant application of 500 pounds per acre of
4-12-12 was disked into the soil. A side-dressing of 300 pounds per acre of
ammonium nitrate was applied on May 14. Additional applications of 100 pounds
per acre of ammonium nitrate were made on June 13, July 17, and August 27. Sevin
was applied at 2 pounds per acre on June 12 and August 25 to control chinch bugs.
Methyl parathion at one-half pound per acre was applied on July 8 to control army
worms. Five harvests were obtained and data are presented in Tables 1-4 with
regard to yield, height, disease, and maturity. Later trials were planted on
May 27 and 28 at ARC, Jay and in the southern part of Santa Rosa County,
respectively. Seeding rates, row spacing, and pre-plant fertilization were like
those previously mentioned. At Jay, applications of 100 pounds per acre of
ammonium nitrate were made on July 17 and August 27. Because of excess moisture
in June at the southern site, 200 pounds per acre of ammonium nitrate were
applied on June 24 and additional applications of 100 pounds per acre on July 18
and August 27. One quart er acre of 2,4-D was applied on June 5 and again on
June 13 at the southern control abundant broadleaf weeds. At the Jay site,
2,4-D was used at one pn l our une 12 and on August 25. Sevin at 2 pounds
per acre was used at te Jay it(( e ne 20, and August 21 to control
chinch bugs. Three ha ests were obta d ah of these trials and data are
presented in Tables 5 7. Rai a 1 was excessive in late July, August, and September.
See Table 14 for rain all dat a/ AR97i Jay.

Trials were als c.4b cted with cultiva of corn and forage sorghum to
determine their poten .foI la e. These ere planted on March 28 at a seeding
rate of 10 pounds of seed pe e' ?/ g and at 30 grains per row for corn.
Rows were on a 36-inch spacing. Ap application of 500 pounds per acre of
4-12-12 was disked into the soil, and a s e-dressing of 300 pounds per acre of
ammonium nitrate was applied on May 14. Following planting, 2 pounds per acre of
Atrazine and 1-1/2 gallons per acre of dinitro were applied as a pre-emergence
herbicide. Corn was thinned on May 7 to a population of 20,000 plants per acre.
Methyl parathion at one-half pound per acre was applied on May 28 and June 12 to
control stink bugs and on July 8 to control a serious outbreak of army worms.
Corn was harvested on July 14 and the sorghum harvest extended from July 15-
August 18 with excessive rain being a factor. The ratoon sorghum crop was sprayed
with 2 pounds per acre of Sevin on August 21 to control chinch bugs and on
October 20 to control midge. One quart of 2,4-D per acre was applied on August 25
to control broadleaf weeds and 200 pounds per acre of ammonium nitrate were
applied on August 27. Freezing temperatures in mid-November resulted in a
pre-mature harvest of the ratoon crop. It should be noted, however, that the rain
caused delay in harvesting the first crop and this delayed the ratoon crop. Data
tor these silage trials are presented in Tables 8-10.

Cultivars of 34 grain sorghums were tested in replicated trials in 1975 to
determine yield, bird depredation, disease resistance, and lodging. In addition,
7 early maturing hybrids were tested for the same characteristics. All cultivars
were planted April 1 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
500 pounds per acre 4-12-12 was disked into the soil on March 21 followed by a
side-dress application of 480 pounds per acre ammonium nitrate on April 29. A
pre-emergence application of Atrazine at 2 pounds per acre applied April 2 and a
post-emergence of 1 pint per acre 2,4-D on June 24 controlled weedy grasses and
broadleaves except for cockleburs which were removed by hand. Soil insect and
nematode control consisted of 20 pounds per acre Furadan applied in a band six
inches deep under the row on April 1 immediately before planting and 20 pounds per
acre Heptachlor applied broadcast over the row on April 3. Methyl parathion at
1/2 pounds per acre was applied on July 8 to control an early outbreak of army
worms.

First harvest, delayed by excessive rainfall (Table 14), was made August 5.
Grain harvest from the ratoon crop was not made because a killing frost occurred
on November 13 before the ratoon crop was mature.

A new foliar disease of grain sorghum was observed in the test plots in late
July and early August. The disease was identified as being caused by Rhiaoctonia
solani and was prevalent on almost all the 34 cultivars grown in the test. Some
cultivars appeared to have some resistance.

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.
