Abstract
Annual cool-season forages can extend forage production and distribution and decrease reliance on supplemental feeding during cooler months in the Southeast region. The planting window for annual cool-season forages ranges from late September through November in South Carolina, and proper nutrient and harvest management should be used to guarantee the proper establishment and production throughout the season. Choosing adequate forage species adapted to each location, weather, and management skills is crucial. In this context, in 2023, a study evaluating cool-season grasses was conducted at the Clemson Research and Education Centers in Blackville (EREC) and Columbia (SREC). Triticale (xTriticosecale Wittmack), wheat (Triticum aestivum), rye (Secale cereale), and ryegrass (Lolium multiflorum) cultivars were managed under two harvest strategies: simulated grazing (three harvests) or baleage production (single harvest). Visual ratings for cold damage and forage accumulation and nutritive value responses were determined in both locations. Trical 344 triticale yielded 3,372 vs 4,371 lbs/a at the EREC and SREC, respectively (Fig. 1). Wheat Gore had 3,336 vs 1,873lbs/a at the EREC and SREC, respectively. Among the ryegrass cultivars, they ranged from 2,284 to 4,603 lbs/a among locations. In terms of crude protein concentration, results were up to 23%. In 2023, field days were held at both locations in March and April, and approximately 90 people attended. In addition, Dr. Silva presented the data in meetings and developed educational online content that disseminated the information further and allowed for additional visualizations (n>200 views). Results emphasize the high quality of cool-season annual forages and their ability to meet nutritional requirements for livestock. Additionally, the interest from producers supports the need to conduct additional data collection and work to provide information on variety selection statewide.
