JAY ARC RESEARCH REPORT-WF73-5 DECEMBER, 1973

VARIETY TRIALS OF SUMMER ANNUAL GRASSES
AND OF FORAGE SORGHUMS FOR SILAGE

L. S. Dunavin1

Variety trials were conducted in 1973 with millets and sorghum X sudangrass

hybrids to determine their potential for grazing, hay, or green chop. These trials

were planted on April 12, 1973 at a seeding rate of i0 Ibs. of seed per acre. Rows

were on a 36-inch spacing. A pre-plant application of 500 Ibs./acre of 0-20-20 was

disked into the soil. A side-dressing of 300 lbs. per acre of ammonium nittate was

applied on May 17. Additional applications of 100 Ibs. per acre of arn-onium

nitrate were made on June 29 and August 27. Two lbs. per acre of Sevin were

applied on June 27 and September 28 to control chinch bugs. Even with these

applications, millet was severely damaged by chinch bugs. Five harvests were

made and data are presented in tables 1, 2, 3, and 4.

Variety trials were conducted with forage sorghums to determine their

potential for silage. Planting date, seeding rate, row spacing, pre-plant

fertilization, and first application of ammonium nitrate were the same as

previously given for the millets and sorghum X sudangrass. Two harvests were made.

The ratoon crop was side-dressed with 200 lbs. per acre of ammonium nitrate on

August 27. Sevin was applied at 2 lbs. per acre in the anthesis stage of each

variety to control midge. Data are presented in tables 5 and 6.
