Matrix Perennial Ryegrass is an outstanding long term persistent ryegrass that is well suited to high performing dairy and beef operations. Matrix is a reliable thoroughly proven perennial ryegrass with it’s late maturity (+23 days compared to Nui) high digestibility, year round yields, strong winter and early spring activity.

Matrix is the grass of choice for persistent ryegrass pastures, as it tolerates a range of management practices, has the ability to respond well to summer rainfall events, resulting in greater leafy summer production, and has shown robust persistent genetics.

The late heading date (+23 days) is ideal for high performing farms as the Matrix Perennial Ryegrass maintains leafy feed through to late spring and early summer, making pasture management easier. The well priced seed and the high annual forage production of Matrix Perennial Ryegrass combined with consistent seasonal growth curves assists farmers in delivering reduced overall feed costs.

Matrix is well suited to sowing in combination with tetraploid perennial ryegrass, such as in Vatbuster, as the Matrix’s tiller density handles heavy grazing well and helps avoid over grazing.
