Kopu II White Clover
High stolen density
Summer & fall growth
Kopu II was selected for stolen density, persistence under grazing, high yield, and large leaf size. This was achieved primarily by selection under cattle grazing in the northern United States and sheep grazing in New Zealand.
Kopu II, bred by AgResearch Grasslands of New Zealand, was selected from a world collection of white clovers. Penn State University and the University of Wisconsin participated in the selection and evaluation of the cultivar. In trials in Lancaster, Arlington, and Marshfield, Wisconsin Kopu II has exhibited improved yield and persistence over Alice (known as the industry standard).
Kopu II outperforms or equals Patriot and Durana in most locations in Kentucky for Persistence and Yield.
Dr. Ken Albrecht, UW-Madison agronomist, approves of Kopu II White Clover.
New hay fields/pasture: 2-4 lbs/acre in mixes
Renovation/Overseeding existing fields/pastures:
3-5 lbs/acre for pastures
Method of Seeding:
Use of a Brillion seeder, a no-till drill or a culti-packer is ideal. Frost seeding also works well, especially if the animals are allowed to "hoof" if into the existing pasture. Seed to soil contact is vital to having a successful stand. Take caution to not plant the seed more than 1/4" deep. For best performance, Kopu II should lightly grazed frequently during establishment.
