Description

POWER Tetraploid Perennial Ryegrass is a late maturing tetraploid perennial ryegrass bred to produce large amounts of high energy forage.

POWER is highly digestible, profuse tillering, and a quick-growing variety. POWER is less sensitive to drought and heat than many ryegrass varieties. Give your animals the energy they need… give them POWER!

Other Info

POWER has been recognized for a number of applications, but is best identified as being the preferred ryegrass for rotational grazing, providing large volumes of easily digestible feed to production animals, such as beef, dairy, sheep and other meat-producing livestock. POWER can also be used in a maintenance diet for horse and other non-production livestock. It is an ideal component in mixtures with other ryegrasses or high palatable grasses and legumes. Use Power as pasture, intensive grazing, green chop, haylage, or dry hay. POWER is also beneficial for use with alfalfa as an establishment crop as well as a final 1-3 year support crop

Seeding Rates:
Tetraploid seed is about twice the size of diploid seed. Seeding rates are higher than diploids.
  Pure seeding: 35-45 lbs/acre
  Mixed with legumes: 35-45 lbs/acre
  New alfalfa seedings (where alfalfa is predominant): 2-3 lbs/acre
  Mixed with other grasses: 10-15 lbs/acre

Renovation/Overseeding existing fields/pastures:
  Pastures: 30-40 lbs./acre
  Alfalfa Hay Field: 5-7 lbs./acre.

Method of Seeding:
Use of a Brillion seeder, a no-till drill or a culti-packer is ideal. Frost seeding and broadcast seeding in early fall timed with moist soil can work well, especially if the animals are allowed to "hoof" it into the existing pasture. Seed to soil contact is vital to having a successful stand. Plant ¼" deep. POWER establishes rapidly, but plants should be firmly rooted prior to first grazing.

Fertility:
POWER is a high-energy grass. Protein content is highly influence by nitrogen fertility. When available, legume-derived nitrogen is preferred - i.e. use of kura, white, or red clover. If no legume-derived nitrogen is available, apply commercial fertilizer or manure at a rate of 50# N/a at planting time and approximately every other grazing. If machine harvesting, 50# N/a should be applied at green-up and after each cutting. Finally, follow soil test recommendations.
