Variety Trials of Summer Annual Grasses, Forage Sorghumst N
For Silage, and Grain Sorghum

L. S. Dunavin and H. A. Peacock& e

Trials were conducted in 1974 with millets and sorghuX udangra ybrids
to determine their potential for grazing, hay, or green cho trials were
planted on April 12, 1974 at a seeding rate of 10 pounds of see d r acre. Ro
were on a 36-inch spacing. A preplant application of 250 pounds 4 re of/
8-24-24 was disked into the soil. A side-dressing of 300 pounds percy
ammonium nitrate was applied on May 10. Additional applications of 100o ds per
acre of ammonium nitrate were made on June 19, July 25, August 19, and September
20. Sevin was applied at 2 pounds per acre on August 9 and September 11 to
control chinchbugs and budworms. Six harvests were obtained and data are
presented with regard to yield, height, disease, and maturity in Tables 1, 2, 3,
and 4, respectively.

Trials were also conducted with cultivars of forage sorghums to determine
their potential for silage. Planting date, seeding rate, row spacing, preplant
fertilization, and first application of ammonium nitrate were the same as given
above for the millets and sorghum X sudangrass hybrids. Two harvests were made.
The ratoon crop was sidedressed with 200 pounds per acre of ammonium nitrate on
August 23. The relatively late planting date of April 12 resulted in a late
first harvest which further resulted in a very late ratoon crop. The ratoon
harvest was made just prior to a killing frost and grain yields were exceedingly
low due to a lack of maturity. Data are presented in Tables 5 and 6.

Four cultivars of sorghum were planted on July 16, 1974 following field corn
and sweet corn. These were side-dressed with 200 pounds per acre of ammonium
nitrate on August 19. Although this planting date of July 16 is only about a week
later than desirable for a late planting of forage sorghum for silage, the
relatively cool temperatures in late October and early November slowed maturity
and reduced grain yields. These grain yields were considerably better than ratoon
crop yields of grain. Data for these plantings following corn are presented in
Tables 7 and 8.

Cultivars of 47 grain sorghums were tested in replicated trials in 1974 to
determine yield, bird depredation, disease resistance, and lodging. All cultivars
were planted April 18 at a seeding rate of 12 seed per foot of row (8 to 12 lbs/A
depending on seed size) in rows 3 feet apart. A preplant application of 250 lbs/A
of 8-24-24 was disked into the soil on April 12 followed by a side-dress application
of 300 lbs/A ammonium nitrate on May 10. A pre-emergence application of Atrazine at
2 lbs/acre applied April 19 and a post-emergence application of 1 pt/acre 2-4,D on
June 5 controlled weedy grasses and broadleaves except for a few morning glory vines
that were removed by hand. First harvest was made August 20. A grain harvest from
the ratoon crop was not made because a killing frost occurred before the ratoon
crop was mature. Data on yield, head type, disease rating, bird damage, height,
and days to heading are presented in Table 9.

Two- and three-year averages of yields of several cultivars grown at the ARC,
Jay are presented in Table 10.
