Russell bermudagrass and other grasses. This trial included four bermudagrass entries and two "volunteer" entries. Russell and Tifton 85 bermudagrass were set in 1995, and Florakirk bermudagrass was set in 1996. DH#1 bermudagrass was set in 1997. Those set after 1995 were set into plots where other entries had been removed. The two volunteer entries consisted of various grasses and weeds. Crabgrass was a big component. In the volunteer plots with the lowest average yield, Cd90160 bermudagrass was planted on 29 June 00; however, in the very dry weather which followed no germination was obtained, and only the volunteers appeared. The trial was located on an Orangeburg sandy loam (Typic Paleudult). An application of 400 pounds per acre of 8-24-24 was made on 13 April 00. Ammonium nitrate was applied at 200 pounds per acre on 11 July 00 and at 100 pounds per acre on 14 Aug. 00. Harvests were made on 29 June, 9 Aug., and 29 Sept. 00. The yields were surprisingly good in view of the hot dry season. Yield data are presented in Table 3. DH#1 produced the highest average total yield, but it was not significantly higher than that of Florakirk. Russell produced the least yield among the bermudagrasses. The yields from the volunteers were relatively low. 'Associate Professor, WFREC, Jay and Professor, NFREC, Marianna.
