Interpretive Summary: not required
Seeded bermudagrasses are very popular with livestock producers because they are less expensive and easier to establish than vegetatively propagated bermudagrasses. Variety trials were planted in Texas, Mississippi, and Georgia in the spring of 2006 to compare seeded varieties and new breeding lines with sprigged varieties. Yields in 2006 were low in Texas and Mississippi because of poor stands due to drought and weeds with maximum yields of 6000 kg/ha in Texas and 8300 kg/ha in Mississippi. In Georgia the soil was fumigated with methyl bromide to control weeds and the study was irrigated resulting in maximum yields of 21,500 kg/ha. In 2007 dry matter yields ranged from 6,400 to 15,600 kg/ha in Texas, from 6,200 to 10,400 kg/ha in Mississippi, and from 8,600 to 30,800 kg/ha in Georgia. Tifton 85 was always one of the highest yielding entries at all locations in 2006 and 2007. Sprigged entries other than Coastal were generally more productive than seeded types. The most productive seeded entries varied with location and year. Across locations and years, Cheyenne, giant, and SWI 810 were frequently some of the more productive seeded entries. This study will be continued through 2008.
