Kingfisher 444 Alfalfa has deep rich green foliage with that extra quality plus high yields. KF 444 will branch root when conditions are wet and works great in heavy wet soil conditions where root rot is a concern, this also aids in the tolerance of heavy wheel traffic at harvest. In addition to rot it has excellent pest resistance. This is a long rotation alfalfa with outstanding persistence this lengthens the production season into late fall harvest. KF 444 scored a good winter survival score of 1.5 from Univ. of WI/MN trials. KF 444 gives the producer a complete package for wide adaption.
- Branch-rooted variety for wetter and heavier clay soils
- Branch root resists heaving
- More traffic and stress tolerant
- Best disease resistance
- Exceptional winter hardiness
Kingfisher 444 is the forage base for many farms today. It is a legume that can fix most of its own nitrogen. Due to the pressures of the rotation schedule on many farms, Kingfisher 444 stands are only in production for three or four years before decreases in productivity are noticed. It is important to get all the yield possible in this short time and these high performing varieties are what we focus on.
Kingfisher 444 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 444 to give a higher tonnage and better quality feed for the life of the stand. Kingfisher 444 exhibits autotoxicity, which means established plants (older than 6 months) give off compounds that prevent new alfalfa seedlings from establishing.
Once established, Kingfisher 444 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 444 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).
