Abstract

Southeastern wildrye (Elymus glabriflorus (Vasey ex L.H. Dewey) Scrib & C.R. Ball) is a relatively new perennial cool-season grass that has shown potential as a forage crop in the Southeastern United States. However, there is a lack of research on this species assessing its agronomic performance. To assess the agronomic performance and it’s tolerance to imazapic field trials were established in Newton and Starkville, MS. A forage production trial included five nitrogen (N) 0, 56, 112, 168, and 224 kg N ha -1 (high input) and five annual clover (low input) treatments. Tolerance to imazapic was assessed with applications of four pre- and early post-emergent applications applied at 0.0, 0.35, 0.7, 0.105, and 0.14 kg ai ha -1. Results from both field trials combine to validate southeastern wildrye as a potential forage crop and continued research and development of agronomic traits in this species.
