Abstract
Abstract Background The incorporation of legumes, specifically alfalfa ( Medicago sativa L.), into bermudagrass ( Cynodon spp.)‐based pasture systems in the southeastern United States has increased in recent years as an alternative to synthetic nitrogen (N) fertilization. Methods A small plot evaluation was conducted in Shorter, Alabama, and Tifton, Georgia, USA, to evaluate the impact of harvest height (HH) and harvest frequency (HF) on agronomic characteristics of alfalfa+bermudagrass mixtures in southeastern United States. Results Results from both locations revealed that the longer the HF and the shorter the HH, the greater the alfalfa retention was in the stand ( p < 0.01). HH did not impact any of the reported nutritive value parameters, while longer HF resulted in lower total digestible nutrients, lower crude protein, higher acid detergent fiber, and lower 48 h in vitro dry matter digestibility ( p < 0.01). Both HH and HF impacted forage accumulation at both locations ( p < 0.01). HH resulted in different trends at each location, while longer frequencies generally increased forage accumulation. Conclusions This research confirmed recent findings from comparable evaluations in the southeastern United States, in that increasing HH and decreasing HF improved alfalfa retention while having a negligible effect on nutritive value or forage accumulation.
