Product Description

KingFisher 406A2 from Byron Seeds is bred for resistance to Aphanomyces Race 2 also known seen as alfalfa root rot. Aphanomyces root rot is identified by the yellowing and stunted nature of the alfalfa plant. Once contracted, alfalfa will likely maintain this disease for the life of the stand. Being Aphanomyces Race 2 resistant, KingFisher 406A2 has immunities to Aphanomyces Race 2, Aphanomyces Race 1, and several other races of Aphanomyces. The KingFisher 406A2 recieves a rank of 2.5 for winterhardiness . KF 406A2 fixes most of its own nitrogen and will perform strongly for 3 to 4 years.

    • One of the most disease resistant – very hearty
    • Fast recovery after harvest
    • A leader in yield
    • Very good forage quality

Establishment

KingFisher 406A2 alfalfa can be planted in the spring or late summer, but we recommend late summer whenever possible. Planting depth should be 0.25 to 0.50 inches with good soil contact. 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 KingFisher 406A2 alfalfa to give a higher tonnage and better quality feed for the life of the stand. KingFisher 406A2 alfalfa exhibits autotoxicity, which means established plants, generally older than 6 months, give off compounds that prevent new alfalfa seedlings from establishing.

Management

Once established, KingFisher 406A2 alfalfa stand can last for many years. Many modern varieties can handle 28 day cutting schedules and in fact, some elite varieties need that type of management to perform their best. One very critical aspect of KingFisher 406A2 alfalfa management is knowing when to take the last cutting in the fall. By using Growing Degree Days (GDD) you can determine the best time to take the last fall cutting. An early fall cut can be taken as long as the plants can accumulate more than 500 GDD to replenish root reserves. A late fall cutting can be taken as long as no more than 200 GDD will accumulate before killing frost (25°F).
