Ranahan Tetraploid Annual Rye Grass


Ranahan is an ideal choice for beef and dairy cattle providing season long production. The higher intake and more digestible fiber of tetraploid ryegrass can mean greater animal performance. Ranahan, with its erect growth, is suitable for green chop, baleage, silage or hay. Late maturity or delayed heading allows for extended grazing for a greater harvest window. The more open sward of a tetraploid ryegrass allows for more diversity of plant species which contribute to soil health, nitrogen fixation, and rumen fill. Ranahan was developed by utilizing the highest-yielding and disease resistant Southern ryegrass cultivars crossed with Peak Plant Genetics private plant collection.

Ranahan readily establishes on loosened bare soil or in close-cut harvested fields. For typical new seeding, applications apply at a rate of 40-45 lbs. per acre. For overseeding and cover crop use seed at a rate of 25-35 lbs. per acre for pastures and 3-5 lbs. per acre into thinning alfalfa stands. Use a Brillion seeder, a no-till drill, or broadcast followed by a cultipacker. Seed to soil contact is critical to successful germination and establishment. For highest hay quality harvest at initial boot stage.


Proper management begins with correct fertilization. Soil sampling is a great tool to get baseline soil fertility inventory, especially on pH, organic matter, phosphorus, potassium and other macro and micro elements to best determine application rates based on soil maintenance and nutrient removal. Correct nitrogen application rates should consider organic matter, yield goals, stocking rate, etc. Your local agronomy input supplier or extension service can provide valuable regional information. Control broadleaf weeds as necessary.
