Determining the ideal time for the first cutting of alfalfa can significantly impact yields and nutritive quality. Weather conditions, targeted harvest schedules, and end goals regarding feed value all play a crucial role in this decision-making process. Sarah Bauder, a forage field specialist at South Dakota State University Extension, emphasizes the importance of considering these factors when scheduling the harvest.
Research conducted by the University of Wisconsin reveals that harvesting more frequently yields high-quality forage with reasonable yields, but compromises stand persistence and plant vigor. Longer harvest intervals, on the other hand, tend to produce higher yields and better stand longevity but lower-quality feeds.
The first cutting of established alfalfa typically offers the highest concentration of digestible fiber for the season. Therefore, it is crucial to determine the appropriate timing for this initial cutting. Instead of relying on uncertain research or the practices of neighboring farmers, Bauder recommends considering the crop's developmental stage as a better predictor.
