Cutting too low can result in damage to the crown and lead to reduced regrowth and yield in subsequent cuttings. On the other hand, leaving too much stubble can result in lower quality forage and increased risk of disease and weed pressure.
Timing of cuttings is equally important. Alfalfa should be cut at the bud stage or when approximately 10% of the plants have started flowering. At this stage, the plant has accumulated maximum energy reserves in its roots and leaves, which translates into higher regrowth potential. Waiting too long to cut can result in decreased yields and forage quality, as the plant diverts energy towards seed production.
### B. Impact of harvest frequency on yield
The frequency of harvests can also impact the overall yield of alfalfa. Generally, alfalfa fields can be harvested every 28 to 35 days during the growing season. However, it is important to consider the growth rate and environmental conditions when determining the frequency of harvests.
Harvesting too frequently, especially in fast-growing conditions, can reduce the yield per cutting. This is because the plant does not have enough time to accumulate sufficient energy reserves for regrowth before the next cutting. On the other hand, waiting too long between cuttings can result in significant yield losses due to increased plant maturity and reduced regrowth potential.
To maximize yield, it is recommended to monitor the growth rate and stage of growth closely. Adjusting the harvest frequency based on these factors can help optimize both yield and forage quality.
In conclusion, proper harvesting techniques, including cutting at the optimal height and timing, as well as managing the frequency of harvests, are crucial for maximizing yield in alfalfa production. By following these guidelines, farmers can ensure not only high yields but also maintain forage quality, resulting in successful hay production.
