Product Description


Byron’s 44 Mag Organic is a tall robust alfalfa with a dense leafy canopy. Alfalfa is a legume that can fix most of its own nitrogen, is deep-rooted to give drought tolerance, and yields well during the hotter part of the summer. On many farms today, alfalfa stands are only in production for three to four years. Byron Seeds selects only the highest-performing varieties for maximum yields throughout the life span of the stand.

The low-lignin industry alfalfas are good quality but they have a drag on yield. Our Byron Seed alfalfas are not only excellent in quality, but they actually increase yield. Byron’s 44 Mag has improved fiber digestibility. Other qualities of Byron’s 44 Mag Organic are:

  • Tall, robust alfalfa variety with a dense, leafy canopy
  • Delivers good tonnage while maintaining high-quality
  • Performs well in short or longer rotations
  • A grower-friendly variety that’s easy to manage
  • Excellent recovery after harvest


Many modern varieties can handle 28-day cutting schedules, and some elite varieties need that type of management to perform their best. Byron’s 44 Mag is flexible; adapted to a 3, 4 or 5 cut system. One very critical aspect of alfalfa management is know when to take the last cutting in the fall. Alfalfa needs five weeks of growth before a killing frost (25 degrees F). 

Higher fall dormancy number in alfalfa indicate early spring and late fall growth, thus increased yield. Byron’s 44 Mag fall dormancy is 4.3. For winter survival, the lower the winter survival number, the more winter hardy the variety. Byron’s 44 Mag winter survival number is 2.2. 


Alfalfa can be planted in the spring or late summer, but we recommend late summer whenever possible. Plant with a drill or Brillion seeder into a firm seedbed: 18-22 lbs./A. If spring sown a nurse crop of grass or small grain is recommended to maximize the tonnage in the seeding year. We usually recommend seeding grass with alfalfa to give a higher tonnage and a better quality feed for the life of the stand.

Good rations of sulfur, boron, and phosphorus as well as a pH above 6.5 are critical for alfalfa. Nitrogen is key for good grass yields. We recommend a soil test. Higher yields and quality starts with good soil. 

Alfalfa exhibits autotoxicity, which means established plants (older than 6 months) give off compounds that prevent new alfalfa seedlings from establishing.
