Cool-Season Forage Variety Trials, WFREC, Jay, FL.,

1999-20001
L. S. Dunavin and C. G. Chambliss2


Cool-season forage trials conducted in
1999-2000 included a ryegrass cultivar trial, a clover
trial including seven species of Trifolium, a trial in
which Flame crimson clover was overseeded on eight
perennial grasses and on prepared seed beds, and an
observation of four entries of cool-season grass.
Some notes are included in regard to chicory.
Climatological data are given in Table 5.

Rvegrass Cultivar Trial. In 1999-2000, the
ryegrass cultivar trial contained 24 entries. It was
planted on 4 Nov. 1999 on a Tifton sandy loam
(Plinthic Paleudult). Seed were broadcast at 20
pounds per acre on a well-prepared seed bed, and the
area was cultipacked following seeding. An
application of 800 pounds per acre of a 4-12-12
fertilizer was disked into the soil prior to seeding.
Ammonium nitrate was applied at 100 pounds per
acre on 5 Jan. and 17 Mar. 2000 and at 200 pounds
per acre on 18 Feb. 2000. Only three harvests were
obtained because of the very dry May. These were
on 16 Feb., 14 Mar., and 26 Apr. 2000. Not enough
rust was observed to rate. Yield data are presented in
Table 1. FLX 1995 (GXS) MR Late (an
experimental line) had the highest average yield


(6,950 lb. dry matter); however, it was not
significantly higher than the yield of 11 other entries.

Clover Trial. The clover trial in 1999-2000
contained 9 entries consisting of seven species of
Trifolium. These were T. incarnatum, Flame and
DWC X P.I. 378130 crimson; T. pratense, Cherokee
red; T. hirtum, ARCJ-44 and Overton x ARCJ-44
rose; T. vesiculosum, Yuchi arrowleaf; T
alexandrinum, Bigbee berseem; T. hybridum, Canada
common alsike; and T. arvense, rabbitfoot. Two
entries, Flame Crimson, and Cherokee Red Clover
are adapted, proven varieties. The trial was planted
on 9 November 1999 on a Red Bay sandy loam
(Rhodic Paleudult) using inoculated seed at 20
pounds per acre for crimson, rose and berseem, 10
pounds for red and arrowleaf and six pounds for
alsike and rabbitfoot Prior to planting, an
application of 300 pounds per acre of 0-20-20
fertilizer was tilled into the soil. After planting, the
area was cultipacked. At the time of planting the soil
was somewhat dry although rain was expected;
however, the only rain for the rest of November was
0.62" on 20 Nov. and 0.11" on 26 Nov. Rainfall was
fair in December and January, somewhat short in
February, adequate in March, rather short in April,

and almost non-existent in May. Stands did not
develop as well as expected. More weeds were
present than anticipated and required some control
measures. The first harvest was not obtained until 18
April 1999, and the only other harvest was made on
24 May 1999. Yields were relatively low and are
presented in Table 2. Although only one year of data
is presented, this trial may indicate the greater
adaptability of Flame Crimson and Cherokee Red
Clover compared to the other entries. The entry ARC
J44 rose clover may have some potential in
Northwest Florida, but requires further testing.

Flame Crimson Clover Overseeded on
Perennial Grass. In this trial, Flame crimson clover
was overseeded on Argentine, Pensacola, Tifton 9,
and Tifton 18 bahiagrass plots and on Tifton 85,
Florakirk, Tifton 78, and Coastal bermudagrass plots.
It was also seeded on four sets of plots, with
well-prepared seed beds, which had contained
grasses in previous years. The clover was planted on
14 December 1999 on an Orangeburg sandy loam
(Typic Paleudult). The seeding rate was 20 pounds
per acre of inoculated seed. Fertilizer was not
applied until 7 Jan. 2000 at which time the
application consisted of 300 pounds per acre of
0-20-20. Rainfall was fair in December and January,
somewhat short in February, adequate in March,
rather short in April, and almost non-existent in May.
In general, the weather was warm, and the grasses
did not really go completely dormant. In early
January and in late February there was very little
clover apparent. By the third week in March, there
appeared to be more clover on the perennial grass
plots than on the well-prepared plots. This was
completely out of line with similar studies in other
years. A harvest was finally obtained on 4 May 2000.
Yields were very low, and these data are presented
in Table 3. There was considerable variability, and
no significant difference existed among the
treatments.

Cool-Season Grass Observation. This trial
contained Surrey ryegrass, Quincy #1 select tall
fescue (an unreleased breeding line), Boreal creeping
red fescue, and Santiam Holcus lanatus. The latter is
known as Yorkshire fog in Britain and as velvetgrass
in the United States. The trial was planted on 23 Nov.
1999 on a Tifton sandy loam (Phinthic Paleudult).


Prior to planting, an application of 800 pounds per
acre of 4-12-12 fertilizer was disked into the soil on
10 Nov. 1999. Ammonium nitrate was applied at 200
pounds per acre on 3 Feb. and at 100 pounds per acre
on 17 Mar. 2000. Harvests were obtained on 17 Mar.
and 5 May 2000. Data are presented in Table 4 and
indicate that the ryegrass was much superior in yield.
The tall fescue was next followed by Holcus lanatus.
Red fescue was last with a very low yield as was
expected.

Chicory. Chicory has been observed at the
West Florida Research and Education Center
(WFREC) for a number of years in two separate
trials. In neither of these trials were stands ever
really what would be desired. In the last of the two
trials an effort was made to improve stands by
overseeding with a little success but not enough. The
last harvest of chicory was made on 30 June 1999.
The highest yield on that date was 2310 pounds per
acre of dry matter (WFREC Res. Rept WF99-12).
An application of 100 pounds per acre of ammonium
nitrate was made to the chicory on 16 July 1999, and
1.5 tons per acre of dolomitic limestone was applied
in late January 2000. No other fertilizer was added in
the cool-season of 1999-2000. No harvests were
made during the season. Stands appeared to be very
poor on 3 Mar. 2000, and weeds were mowed off on
22 Mar. 2000. Stands were rated on 9 June 2000 and
varied from an estimated low of 2% to a high of
50%.
