Product Description


KingFisher SynergyX Blaze HD2 is a blend of high-performing alfalfas focused on highest digestible quality and highest disease resistance. Blaze is naturally bred for reduced crosslinking with lignin and lower UNDF240 and Blaze maintains it forage quality across varying cutting systems. Increased persistence through synergistic tap and branch rooting systems as well as the strong disease resistance (APH2 resistant) of this blend brings incredible longevity and consistent quality. Blaze is selected for increased NDF30 and protein digestion to boost livestock performance, bringing greater profit potential to your farm. 

  • Disease Resistance  30-35
  • Dormancy 4.5 (early spring and later fall growth)
  • Branch root and tap root blend

SynergyX Blaze HD2 can fix most of its own nitrogen. SynergyX Blaze HD2 has increase digestibility. The varying root system feed the plants whether it’s warm or cool, wet or dry. Alfalfa stands usually last  3-4 years. Byron seeds selects only the highest-performing varieties for maximum yields through-out the life span of the stand. 


Many modern varieties can handle 28-day cutting schedules, and some elite varieties need that type of management to perform their best. One vary critical aspect of alfalfa management is knowing when to take the last cutting in the fall. Alfalfa needs five weeks of growth before a killing frost (25 F degrees). In some areas, another cutting can be taken after frost when the alfas is dormant.

Higher fall dormancy numbers in alfalfa indicate early spring and late fall growth, thus increased yield. For winter survival, the lower the winter survival number, the more winter hardy the variety.  


Alfalfa can be planted in the spring or late summer, but we advise late summer when possible. If spring sown, a nurse crop of grass or small grain is advisable to maximize the tonnage in the seeding year. We usually advise seeding grass with alfalfa to increase tonnage and produce a better quality food for the life of the stand.

Good ratios of sulfur, boron, and phosphorus as well as a pH above 6.5 are critical for alfalfa. Nitrogen is key for good grass yields. Plant with a drill or Brillion seeder into a firm seedbed; 18-22 lbs./A.

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