Variety Trials of Summer Annual Grasses, Sorghum and Corn for ,

Silage, Red Clover, White Clover and Grain Sorghum /

L. S. Dunavin, H. A. Peacock, and D. W. Gorbet1

Summer Annual Grasses:

The summer annual grass trial contained nine millets and eleven sorghum X

sudangrass hybrids in 1986. These were planted on March 31, 1986 in four repli-

cations. The seeding rate was ten pounds per acre. The trial was planted in

rows spaced three feet apart. For the use of those who would like to convert to

metric units, the conversion factors are given in Table 1. This trial was locat-

ed on an Orangeburg sandy loam soil (Typic Paleudult). An application of 300

pounds per acre of an 8-24-24 fertilizer was applied and disked into the soil on

March 26, 1986. Ammonium nitrate was applied at 200 pounds per acre on April 25,

and at 100 pounds per acre on May 30, June 30, and August 4. Portions of the

summer of 1986 were very hot and climatological data are presented in Table 2.

Harvests were made on May 28, June 27, August 1, and September 18. Data for yield,

height, disease, and maturity are presented in Tables 3, 4, and 5.

Sorghum and Corn for Silage:

Six forage sorghums, one sorghum X sudangrass hybrid, and five corns were

evaluated in 1986 for silage potential. This trial was planted on April 1, 1986

in four replications. The seeding rate for sorghum was ten pounds per acre, and

corn was planted at forty grains per 16-foot row and later thinned to 22 plants

per row. Rows were on a 3-foot spacing. An application of 300 pounds per acre of

an 8-24-24 fertilizer was disked into the soil on March 26. Ammonium nitrate at

200 pounds per acre was applied on May 5 and again a few days following the first

harvest of each variety. The soil was an Orangeburg sandy loam (Typic Paleudult).

The first harvest began on July 10 and continued through July 22 as varieties be-

came ready. The second or ratoon harvest began on October 3 and was completed on

October 20. Data on yield, lodging, height, and disease are presented in Tables

6, 7, and 8.

Red and White Clover:

Second-year data were obtained on red and white clovers which were spring-

planted on March 27, 1985 following the loss of the fall-planted clovers. The

soil was an Orangeburg sandy loam (Typic Paleudult). Data from harvests made on

April 16, June 11, and September 2 are presented in Table 9. Following the

September harvest, the red clovers died and growth of the white clovers was

reduced for a period of time. On January 20, 1987 the stands of Osceola were very

good and the stands of La. S-1 were fair to good.

Grain Sorghum Jay:

Cultivars of 66 grain sorghums were tested in two replicated trials in 1986

on a Red Bay sandy loam (Rhodic Paleudult) to determine yield, height, heading

date, lodging, and disease reaction. All cultivars were planted 9 April at a seed-

ing rate of 12 seed per foot of row [8 to 12 Ibs seed/A (8.9 to 13.4 kg/ha) depend-

ing on seed size] in rows 3 feet (0.9 m) apart. A preplant application of 500

lbs./A (560 kg/ha) of 8-24-24 fertilizer was disked into the soil'and 200 lbs./A

(224 kg/ha) ammonium nitrate was applied as a top dressing. A preemergence applica-

tion of 1 lb. of atrazine and 4 lbs. of propachlor per acre (1.12 and 4.5 kg/ha,

respectively) controlled weedy grasses and broadleaves except nutsedge and morning-

glory. Soil insect control consisted of 20 lbs./A (22.4 kg/ha) Furadan applied in

a band of 6 inches (15.24 cm) deep under the row before planting. Grain was har-

vested 14 August and dried to 12% moisture before weighing. One test was rainfed;

the other was irrigated enough to prevent the sorghum from going into drouth

stress. A heavy rain and windstorm on 2 August lodged all entries; thus, lodging

ratings were not made.

Yields were good for most cultivars but final yields were only a little

better than in 1985 because of the lodging, pre harvest seed sprouting, and shedding

of the grain. Data on yield and other agronomic characteristics are presented in

Table 10. The highest yielding hybrids in the irrigated test were Sunbelt 444 with

5960 lbs. grain per acre (6680 kg/ha), followed by Agra Tech GK-712G with 5810 Ibs.

grain per acre (6510 kg/ha), and McCurdy 84-74 and Conlee Tophand II with 5730

lbs. grain per acre (6420 kg/ha). The highest yielding hybrids in the unirrigated

test were Pioneer 8226 with 5350 Ibs. grain per acre (5990 kg/ha), followed by

Asgrow Colt with 5200 lbs. grain per acre (5820 kg/ha). Several other hybrids in

both the irrigated and unirrigated yielded more than 5000 lbs. grain per acre

(5600 kg/ha), approximately 83 bushels per acre which is 23 bushels per acre more

than the average yield from 64 corn hybrids in unirrigated test plots in 1986.

Two-, three- and four-year average yields of several hybrids grown at AREC, Jay

are presented in Table 11. The highest yielding hybrid averaged over four years

was Asgrow Colt. The highest yielding hybrid averaged over three years was Northrup

King Savanna 5. The highest yielding hybrid averaged over two years was Northrup

King 2665.

Leaf diseases were evident (primarily anthracnose, Colletotrichum graminicola)

but were not severe enough for a differential variety reaction. Therefore, ratings

were not made.

Grain Sorghum Marianna;

Two plantings of commercial grain sorghum hybrids were made at the AREC,

Marianna on 9 April and 18 July. Both plantings were irrigated. The two tests had

48 entries each. Yield and other data from the April and July plantings are present-

ed in Tables 12 and 13, respectively, Three-year yields and two- and three-year

average yields are presented in Table 14. The highest yielding hybrid over three

years was Young ORO T XTRA with 6000 lbs. per acre grain (6720 kg/ha).
