Cool-Season Forage Trials, 1994-1995 University of Florida

L. S. DunavinI

Several cool-season forage trials were conducted in 1994-1995. These included
two ryegrass cultivar trials, a fescue cultivar trial, clovers on sod, and red
and crimson clovers grown alone.and with rye and ryegrass.

Conversion factors from English to metric units are presented in Table 1, and
climatological data are presented in Table 2.

Ryegrass Cultivar Trial. This trial contained 12.cultivars and was planted on
October 20, 1994 on an Orangeburg sandy loam soil (Typic Paleudult). The seed-
ing rate was 20 pounds per acre. Following seeding, the area was cultipacked.
Prior to seeding, an application of 500 pounds per acre of an 0-30-15 fertilizer
was disked into the soil. On the date of seeding, ammonium nitrate was applied
at 100 pounds per acre and at the same rate on January 12, February 23, March
24, and May 04, 1995. Four harvests were obtained, and yield data are presented
in Table 3. Rust data are presented in Table 4.

Ryegrass Cultivar Trial #2. This trial contained only five cultivars and was
planted to include an entry which arrived after all entries were thought to be
here, and the first trial had already been planted. This trial was also planted
on an Orangeburg sandy loam soil (Typic Paleudult) although in a different area
of the research center than the previous trial. It was planted on October 27,
1994. Prior to planting, an application of 400 pounds per acre of an 8-24-24
fertilizer was disked into the soil. Ammonium nitrate was applied at 200 pounds
per acre on February 03, 1995 and at 100 pounds per acre on March 06 and April
10, 1995. Four harvests were obtained, and yield data are presented in Table 5.
Yields were much higher in this trial than in the previous trial.

Fescue Cultivar Trial. This trial contained 16 entries and was planted on Novem-
ber 16, 1993 on an Orangeburg sandy loam soil (Typic Paleudult). An application
of 300 pounds per acre of an 8-24-24 fertilizer was made on September 29, 1994.
Ammonium nitrate was applied at 200 pounds per acre on December 14, 1994 and
March 06, 1995 and at 100 pounds per acre on September 29, 1994 and April 10,
1995. Four harvests were obtained, and yield data are presented in Table 6. These
yields were not very high but were somewhat higher than in the first year of the
trial.

Clovers on Tifton'78 Bermudagrass Sod. This trial contained eight clovers which
were top-seeded on Tifton 78 bermudagrass sod on December 07, 1994. Seeding rates
were 20 pounds per acre for berseem, crimson, and rose clovers, 10 pounds for red
clover and 6 pounds for white, alsike, and arrowleaf. The sod was located on a
Tifton sandy loam soil (Plinthic Paleudult). The bermudagrass had been invaded by
a considerable amount of bahiagrass. Seed were inoculated and broadcast by hand.
They were dispersed in damp sand. An application of 400 pounds per acre of 0-30-15
fertilizer was applied on December 12, 1994. Pure clover yields were determined,
and data through June 16, 1995 are presented in Table 7.

Red and Crimson Cldvers'Al6rn and With-Ryearid'Ryegrass. This trial was excerpt-
ed from a larger trial containing more.treatments'and comparisons. These data will
be made available later in another report. Thisexcerption was analyzed as though
it were a single randomized complete block trial. Cherokee red and Flame crimson
clover were planted alone and in combination with Surrey ryegrass and Fla. 401 rye
on October 18, 1994 on an Orangeburg sandy loam soil (Typic Paleudult). Prior to
planting, 500 pounds per acre 0-30-15 fertilizer was disked into the soil. At
planting, 130 pounds per acre of ammonium nitrate was applied. A harvest which
contained mostly rye was made on February 01, 1995, and subsequent harvests were
obtained on March 22, April 19, and May 22. Yield data are presented in Table 8.
Further production from red clover was expected in June and possibly also in July;
however, these data will be presented in a later report. Although the seasonal
totals through May 22 were not statistically different due to considerable
variability among replications, those entries containing red clover had higher
average yields.
