Lowboy
Annual Ryegrass
An innovative new tool for cover crop systems.
LowBoy is as easy to terminate as it is to plant, giving it an edge over traditional annual ryegrasses used for cover cropping. Its unique growing habit reduces weeds, yet allow for other cover crop species. LowBoy is deep-rooted and cold-tolerant too, making it an ideal cover crop tool.

Great Ground Coverage
Compared to other annual ryegrasses, LowBoy has much more aggressive tillering. This spreading effect minimizes bare soil, runoff, evaporation, and unwanted weeds during the growing season.
Easy To Terminate
LowBoy’s narrower leaves and reduced top growth make it easier for late-season termination, especially during wetter springs.
Deep and Wide Roots
LowBoy's roots go deep. They also go wide helping retain soil, absorb water and create an abundance of root channels.
Cold Tolerant
LowBoy has shown good cold tolerance in Midwest trials.
Planting Green & No-Till
Thanks to its shorter canopy and minimal residue, LowBoy is ideal for planting green and no-till crop establishment.
Endophyte-Free
While used primarily as a cover crop, LowBoy is also safe for all livestock and free of toxic endophyte.
Strengths
Stays Low to the Ground
LowBoy covers more ground. Compared to other annual ryegrasses, LowBoy has much more aggressive tillering. This spreading effect minimizes bare soil, runoff, evaporation, and unwanted weeds during the growing season. LowBoy is truly excellent temporary ground cover.
Easy Termination
When late spring arrives, LowBoy goes away with ease, making transition to row crops or warm season crops easy. Compared to traditional ryegrasses, LowBoy has significantly less top-growth. Excessive top-growth can be difficult to burn down chemically as well as hinder no-till seeding and sufficient light penetration to dry out and warm up soil. LowBoy is there when you need it, and leaves when you don’t, allowing easier establishment of primary crops, such as corn and soybeans.
Plays Well With Others
LowBoy is an excellent grass to use in multi-species cover crop mixtures. It germinates quickly, fills in at the crown, but doesn’t overwhelm other components with excessive height and lodging. Use it with small grains, brassicas, and legumes.
An example of this is shown in this video out of eastern Pennsylvania where Lowboy was planted with Dixie crimson clover.
Deep and Dense Root System
In multiple evaluations, LowBoy has demonstrated an extensive root system with two predictable characteristics. First, LowBoy’s has very dense roots directly under each plant. These roots are wide and thick, penetrating soil with countless channels. Second, LowBoy sends roots deep. In soil pit/plug studies LowBoy demonstrated root depths as deep, if not deeper than other well-known cover-crop ryegrasses.
Cold Tolerance
LowBoy has shown very good cold tolerance throughout the country, providing confidence in use throughout the United States. PLUS, LowBoy doesn't produce excessive tonnage at the end of the season, making termination much easier.

Testimonials
After looking at Lowboy for 2 years in 2016 and 2017, I would describe it as a low growing annual ryegrass that has aggressive tillering. It is not a product I would recommend as a forage but is great for use in cover crop situations. With our Carter Harvester, which is a flail mower, after harvesting across the plots, the other traditional annual ryegrasses you can see the individual rows (7” spacing) after harvesting. With the Lowboy, the rows were almost completely filled in.
