Conversion factors are given in Table 1 for the use of those who would like to
convert to metric units. Climatological data are presented in Table 2.

Warm-season perennial grasses.
Nine grasses were included in this trial in 1997. Three included in 1996 no long-
er had sufficient stands in 1997. The bahiagrasses and Suerte atra paspalum were
planted on 22 April 92, and rooted plants of all others except Tifton 85 and
Coastal bermudagrass were set on 23 April 92. Tifton 85 was set on 14 April 93,
and Coastal was set on 18 April 94. The trial was located on an Orangeburg sandy
loam (Typic Paleudult). An application of 400 pounds per acre of an 8-24-24 fer-
tilizer was made on 24 March 97. Ammonium nitrate was applied to supply 50 pounds
per acre N on 24 April, 6 June, 9 July, 6 Aug., and 5 Sept.. Gypsum was applied
at 125 pounds per acre on 24 March. Harvests were obtained on 22 April, 2 June,
2 July, 4 Aug., 3 Sept., and 1 Oct. 97. Yields of dry matter are given in Table
3. Late August and most of September were very dry, and the harvest in October
reflects this.

Russell bermudagrass and other grasses;
Observations were made in 1997 in a trial containing Russell bermudagrass and
Tifton 85 bermudagrass which were set in 1995 and Florakirk bermudagrass which
was set in 1996. Also included were Carostan flaccidgrass which was planted in
April, 1996, and DH #1 bermudagrass and Cd 90160 bermudagrass which were set
and planted respectively on 22 May 97. An application of 400 pounds per acre
of an 8-24-24 fertilizer was made on 24 March 97 along with 125 pounds per
acre of gypsum. Ammonium nitrate was applied at 100 pounds per acre on 1 May,
17 July, and 19 August 97 and at 200 pounds per acre on 19 June 97. Harvests
were obtained on 30 April, 11 June, 15 July, 14 August, and 9 September. Data
are presented in Table 4 and indicate that Tifton 85 was the highest yielder
of dry matter. Florakirk and Russell were essentially equal in yield followed
by DH #1. Carostan did not have a very good stand in 1996 and appeared to have
an even poorer stand in 1997. Cd 90160 ( did not come up very well and had a
very poor stand.

Suerte atra paspalum-Carostan flaccidgrass-Red River crabgrass.
A trial was continued in 1997 to observe Suerte atra paspalum, Carostan flaccid-
grass, and Red River crabgrass. This trial was planted in April, 1996 except Red
River was planted on May 5, 1997 and is located on an Orangeburg sandy loam soil
(Typic Paleudult). An application of 300 pounds per acre of an 8-24-24 fertilizer
was made on May 5, 1997. Ammonium nitrate was applied at 100 pounds per acre on
9 July and at 200 pounds per acre on 6 August. Harvests were obtained on 11
April, 24 June, 5 August, and 5 September. Yield data are presented in Table 5
and show no significant difference between Suerte and Carostan with respect to

total yield. Red River yielded considerably less although the stand was much
better in 1997 than in 1996.

Bahiagrass cultivar trial.
A new bahiagrass trial was planted on 16 April 97. on a Dothan fine sandy loam
soil (Plinthic Paleudult). These plots were seeded at a rate of 20 pounds per
acre. An application of 400 pounds per acre of 8-24-24 fertilizer was made on
26 March 97. Ammonium nitrate was applied at 100 pounds per acre on 10 July and
19 August 97. Harvests were obtained on 10 July, 14 August, and 12 September 97.
Yields among the top three: Tifton 23, Tifton 18, and Tifton 9 were not signifi-
cantly different. Data are presented in Table 6.

Gamagrass.
Observations were continued on three ecotypes and a cultivar of Eastern gama-
grass. These observations were made on single plants (replicated four times) set
on four-foot centers. The plants were set on 29 March 93. They had developed
into relatively large plants. The ecotypes were from Alabama, Tennessee, and
Florida. The cultivar 'Pete' was released in 1988 by the USDA-SCS in cooperation
with the Kansas and Oklahoma Agricultural Experiment Stations and the USDA-ARS.
The plants were located on an Orangeburg sandy loam soil (Typic Paleudult). An
application of 400 pounds per acre of 8-24-24 was made on 2 May 97, and ammonium
nitrate was applied at 100 pounds per acre on 6 June, 9 July, and 20 August 97.
Data are presented in Table 7 and show that the Alabama ecotype was the most
productive.

Summer annual grasses.
No trial of summer annual grasses has been conducted at WFREC, Jay for the past
two years; however, a trial is planned for 1998. Since no trial was conducted
in 1997, a table of yields of entries during 1990-1995 has been included in this
report. It is presented in Table 8 and includes five millets and eight sorghum X
sudangrass hybrids. An average yield is shown; however, remember to consider the
variability in years of testing.

Temperate corn.
Cultivars of 25 corn hybrids were planted in a replicated field trial in 1997 on
an Orangeburg fine sandy loam to determine yield and ear quality. All hybrids
were planted 25 March at a seeding rate of two seeds per foot of row in rows
three feet apart. A preplant application of 700 lb/acre 3-9-18 was applied broad-
cast and disked into the soil 19 March. A topdressing of 300 lb/acre ammonium
nitrate was applied when the corn reached the 5-leaf stage. Other normal farming
practices were applied to the experimental area. Grain was harvested and dried to
12% moisture before weighing for yield. Precipitation at WFREC, Jay is shown in
Table 9.

May rainfall was normal while June was above normal; thus the corn grew off well
and all entries except one produced more than 100 bu/acre grain (Table 10). DeKalb
687 was highest in yield with 162.1 bu/acre grain followed by Northrup King 8811
with 150.4 and AgriPro AP9707 and DeKalb 706 with 138.7 bu/acre grain.

Two-, three-, and four-year average yields of corn hybrids grown at WFREC, Jay
are presented in Table 11. The highest yielding hybrid averaged over two years
was DeKalb 687; over three years was DeKalb 706; and over four years was Northrup-
King 8811 followed by DeKalb 714 and AgraTech 888.









Grain sorghum Jay.
Cultivars of 41 grain sorghum hybrids were planted in a replicated field trial
in 1997 on an Orangeburg fine sandy loam to determine yield, heading date, head
type, disease reaction, lodging, height, and bird depredation. All hybrids were
planted 8 May at a seeding rate of 10 seed per foot of row (8-12 lb seed/acre
depending on seed size) in rows 3 feet apart. A preplant application of 500 lb/
acre 3-9-18 was disked into the soil and 200 lb/acre ammonium nitrate was
applied as a topdressing on 8 June. A preemergence application of 1 lb atrazine
and 4 Ib propachlor/acre controlled weedy grasses and broadleaves except morn-
ingglory. Grain was harvested and dried to 12% moisture before weighing for
yield.

Yields were poor for most hybrids with the test average being 4162 Ib/acre,
about half the normal yield for the WFREC at Jay (Table 12). Rainfall was-25.7
inches from 8 May through 30 August. The 49-year average for the same period at
WFREC, Jay was 26.39 inches. Therefore it appears rainfall was not a limiting
factor in yield. On average, in 1997, grain sorghum hybrids yielded 61.5 bu/acre
less than average corn hybrids grown in 1997.

There was no lodging, bird depredation, or preharvest seed sprouting in 1997.
Leaf diseases were, on average, no more severe than in recent years (primarily
anthracnose, Colletotrichum graminicola. The seedlings were slow to emerge and
seemed slow in beginning to grow.

Data on yield and other agronomic characteristics are presented in Table 12.
The highest yielding hybrid in the test was DeKalb DK52 followed by Novartis
Savanna 5, DeKalb DK64, and DeKalb DK54. Only 7 of the 41 hybrids produced more
than 5000 lb/A grain.

Two-, three-, four-, and five-year average yields of hybrids grown at WFREC, Jay
are presented in Table 13. The highest yielding hybrid averaged over two years
was Novartis Savanna 5 followed closely by DeKalb DK 52; over three years was
Novartis Savanna 5 followed by AgriPro HSC Wings and AgriPro Cherokee; over four
years was Triumph Two 80-D, AgriPro HSC Wings, and Cargill 837; and over five
years was Triumph Two 80-D, AgriPro HSC Wings, and DeKalb DK 54.

Grain sorghum Marianna.
Two plantings of grain sorghum were made at NFREC, Marianna in 1997 on Chipola
loamy sand. The early planting of 41 hybrids was made 25 April. The late plant-
ing of 39 of the 41 hybrids was made 11 July. The April planting was irrigated
2 times for a total of 1.6 inches of water and was fertilized with 400 lb/acre
18-9-18 preplant incorporated, 350 lb/acre 13-13-13 on 9 May, and 200 lb/acre
ammonium nitrate on 4 June. Data on yield and other agronomic characteristics
are presented in Table 14. The highest yielding hybrid was DeKalb DK54.followed
by DeKalb DK 55, and Novartis Savanna 5. The mean yield of the test was 4055
lb/acre grain.

Data on yield and other agronomic characteristics from the late planting at NFREC,
Marianna are presented in Table 15. The late planting of 39 hybrids was made 11
July and was irrigated 8 times for a total of 7.5 inches water. It was fertilized
with 350 lb/acre 13-13-13 on 27 July and 13 August and 200 lb/acre ammonium
nitrate on 14 August. The highest yielding hybrid was Novartis Savanna 5 followed
by Novartis KS 989 and DeKalb DK 55. The mean yield of the test was 2823 Ib/acre
grain, with highest yield 4598 lb/acre.










.Data from the early plantings at NFREC, Marianna and WFREC, Jay and the 2-loca-
tion average yields are presented in Table 16. The highest yielding hybrid from
the average of the two locations was DeKalb DK 54 followed by Novartis Savanna
5 and Novartis KS 936. The overall mean yield for the two locations was 4108
lb/acre grain.

Table 17 lists the sources of seed for the 1997 grain sorghum tests grown at
WFREC, Jay and NFREC, Marianna.
