Variety Trials of Summer Annual Grasses, Sorghum and Other Crops

for Silage, Alfalfa and Clover, and Grainj S' gum t L.- ;

L. S. Dunavin and H. A. Peacock pn ;j

Summer Annual Grasses:..

In 1983, there were twenty sorghum X sudangrass hybrids-and five millets in

the summer annual grass variety trial. One forage sorghum was also included. These

were planted on May 10 in rows spaced three feet apart. This was a late planting

and was due to loss, because of very excessive packing rain, of the original plant-

ing made on April 13. The seeding rate was 10 pounds per acre. For the use of those

who would like to convert to metric units, the-conversion factors are given in

Table 1. The trial was located on a Dothan fine sandy loam soil (Plinthic Paleudult).

An application of 250 pounds per acre of an 8-24-24 fertilizer was applied and

disked into the soil on April 6. Ammonium nitrate was applied at 200 pounds per acre

on June 1 and at 100 pounds per acre on July 7 and August 10. Loss of the first

planting and the late planting reduced the number of harvests in 1983. Harvests were

made on July 5, August 4, and September 16. Data are presented in Tables 2 and 3.

Sorghum, Corn, and Millet for Silage:

Four sweet sorghums, twelve forage sorghums, three corns and one millet were

tested for silage potential in 1983. This trial was planted on May 10 in rows spaced

three feet apart. This was a late planting and was due to loss, because of very

excessive packing rain, of the original planting made on April 13. Sorghum and

millet were planted at a seeding rate of 10 pounds per acre. Corn was planted at 40

grains per 16-foot row and thinned on June 2 to 22 plants per row. An application

of 250 pounds per acre of an 8-24-24 fertilizer was applied and disked into the

soil on April 6. This soil was a Dothan fine sandy loam (Plinthic Paleudult). An

application of 200 pounds per acre of ammonium nitrate was made on June 1, and

another application at the same rate was made on September 2 to varieties already

harvested and to other varieties on September 7 and 9 following harvests. An

application of 1.5 pounds per acre of atrazine and one quart per acre of Agri-Dex

was made on June 8 for weed control. The first harvest began on August 8 with the

varieties ready at that time and was completed on September 8 when MN1500 was

harvested due to very severe lodging and 911 was harvested to complete the field

since it would not head until October anyway. Intermittent spraying with Sevin XLR

was done as varieties came into anthesis prior to the ratoon harvest in order to

control the midge. The ratoon harvest was-made on November 8 since night tempera-

tures had already dropped to 370F and were expected to drop below freezing as

they did a few nights later. Data are presented in tables 4, 5, 6, and 7.

Alfalfa and Clover:

Two alfalfas and a white clover were planted on November,13, 1981 on a Dothan

fine sandy loam (Plinthic Paleudult). Yields for 1982 were presented in Jay, ARC

Research Report WF83-2. On October 5, 1982 3 pounds per acre of elemental boron

were applied as solubor along with 200 pounds per acre of 60% muriate of potash.

An application of 250 pounds per acre of 0-30-20, 200 pounds per acre of 60% muriate

of potash and 20 pounds per acre of solubor (4 pounds B) was made on April 20, 1983.

Harvests in 1983 were made on April 19, May 17, June 13, July 12, August 12, and

September 27. This white clover has recently been released under the name Osceola.

A special harvest of this clover was made on December 27, 1982 at which time it was

growing extremely well. On this date, the clover was 8 inches in height, was not

blooming and produced 1500 pounds per acre of dry matter. Data for 1983 are present-

ed in Table 8. It should be noted that considerable stand loss of alfalfa occurred

in 1983 and by October 19 no plot of alfalfa in the trial had what could be consid-

2 -








ered a satisfactory stand. Insects did a lot of damage in the late summer and early

fall, and the wet spring of 1983 probably helped cause an increase in leaf and stem

diseases. The exact cause of stand loss has not been definitely identified.

Precipitation:

Rainfall was excessive in the first four months of 1983, and the total for the

year was 1.25 times more than the 35-year average. Based on the averages, May was

relatively dry, and July, August, September and October were below average. Novem-

ber was on the wet side and December was very wet. Data are presented in Table 9.

Grain Sorghum:

Cultivars of 72 grain sorghums were tested in replicated trials in 1983 on a

Red Bay sandy loam (Rhodic Paleudult) to determine yield, height, lodging, disease

resistance, bird damage, heading date and head type. All cultivars were planted

March 31 at a seeding rate of 12 seed per foot of row [8 to 12 pounds seed per

acre (8.9 to 13.4 kg/ha) depending on seed size] in rows 3 feet (0.9 m) apart. A

preplant application of 500 pounds per acre (560 kg/ha) of 8-24-24 was disked into

the soil and 250 pounds per acre (280 kg/ha) ammonium nitrateiwas applied May 9. A

preemergence application of 1 pound of atrazine and 4 pounds of propachlor (1.12

and 4.5 kg/ha, respectively) controlled weedy grasses and all broadleaves except

morningglory. Soil insect control consisted of 20 pounds per acre (22.4 kg/ha)

Furadan applied in a band 6 inches (15.24 cm) deep under the row before planting.

Grain was harvested July 28 and dried to 12% moisture before threshing and weighing.

Yields were good for most cultivars. Data on yield and other agronomic charac-

teristics are presented in Table 10. The highest yielding cultivars were DK-64A

(DeKalb) with 8280 pounds grain per acre (9270 kg/ha) and Two 80D (Texas Triumph)

with 7740 pounds grain per acre (8670 kg/ha). Several cultivars, DK-64 (DeKalb),

W-851 DR (George Warner), and 6658 (PAG) yielded more than 7000 pounds grain per

acre (7840 kg/ha), approximately 117 bushels per acre. Two- and three-yeaK average

yields of several cultivars grown at ARC, Jay are presented in Table 11. The highest

3 -








yielding cultivar averaged over three years was M-57YG (McCurdy). The highest

yielding cultivar averaged over two years was DK-64A (DeKalb).

A late season trial of 16 cultivars was planted July 22 on Orangeburg sandy

loam at the same seeding rate as that used in the March planting. A preplant

application of 500 pounds per acre (560 kg/ha) of 8-24-24 was disked into the soil

and the plants were top dressed with 100 pounds per acre (112 kg/ha) ammonium

nitrate. Grain was harvested after first killing frost (harvested November 24)

and dried to 12% moisture before threshing and weighing. Data are presented in

Table 12. Yields were good with Savanna 5 (Northrup King) producing 5280 pounds grain

per acre (5910 kg/ha) followed by RA787 (Ring Around) with 4690 pounds per acre

(5250 kg/ha) and DK-64 (DeKalb) with 4650 pounds per acre (5110 kg/ha). Leaf

diseases were evident but were not rated.
