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. Ryegrass 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 l6 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,

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%. NOTE: This extension fact sheet is an adaptation of WFREC Research Report WF00-11.
