Product Description

Jumbo is a higher yielding, later maturing, and winter-hardy modern tetraploid variety suitable for both grazing and mechanical harvesting, developed by Dr. Gordon Prine at the University of Florida. The superior rust resistance of Jumbo in varied environments is legendary. Jumbo has consistently performed well in forage trials throughout the annual ryegrass growing regions of the U.S. Jumbo exhibits cold tolerance, vigorous growth habit and high forage yields. The variety is suitable for mechanical harvesting (silage) as well as grazing.

  • Tetraploid
  • High sugar content
  • Rust Resistant
  • Late Maturity
  • Excellent Regrowth

Forage trials throughout the South prove Jumbo to be superior in yield and regrowth. Cold injury ratings performed in Ardmore, OK prove Jumbo to have superior winter-hardiness. Disease screenings performed at Beaumont, TX and Gainesville, FL prove Jumbo to have superior resistance to gray leaf spot and crown rust. Jumbo not only delivers higher yields with a larger plant, it also delivers higher quality forage through disease and weather resistance.

Annual Ryegrass

Annual Ryegrass establishes very rapidly, which gives high productivity in the planting season. Annual ryegrass is one of the best choices for overseeding warm season pastures cover crop because of its versatility, ease of establishment, amazing root system, and incredible nutrient scavenging abilities. It is an excellent soil builder, great at erosion control and weed suppression. The massive root system can add 5000 – 9000 lbs of organic material per acre, growing down to 54 inches, providing channels for air, water, and following crop root systems. Farmers have reported corn root zones down to nearly 5 feet following ryegrass. Annual ryegrass is best suited for grazing or harvest as silage. Annual Ryegrass is also used as a cover crop all across the Midwest.

Establishment

Drill at 15-25 lbs/Acre, 1/4 to 1/2 inch deep or fly on into standing corn at the higher rate. You can also broadcast onto bare soil and roll with a cultipacker. Seed 40 days before killing frost date to help protect from winter kill. Annual ryegrass rates in mixes can be cut to 8-15 lbs.

Management

Annual ryegrass has extremely fast emergence and establishes quickly on a variety of soil types. It works well alone or in mixes. In severe winter conditions, annual ryegrass can winter kill, but roots have usually grown down 24-32 inches, sequestering leftover nutrients and providing a good start for the following crop. Incorporation will work to kill ryegrass if it is completely covered. If using glyphosate, apply a full rate when the days are warm, averaging over 50°F and the grass is growing vigorously.
