Long Rotation Ryegrass

Long rotation ryegrasses generally fall between perennial and hybrid ryegrass in growth and persistence. Their genetic composition is mostly perennial ryegrass, but may contain up to 25% annual or short rotation ryegrass. Long rotation ryegrasses are mainly used in summer wet areas where they can show good persistence. >> View Catalogue

Short Rotation

Short rotation ryegrass and annual ryegrass are discussed together as they are usually used for the same purpose. Most commonly they are sown for a high quality short term winter crop, to provide multiple grazings in winter and spring. They are also undersown into run out pasture to boost its winter and early spring performance.

Short rotation ryegrass is more persistent and can be sown for a 2-3 year pasture where Argentine Stem Weevil (to which it is susceptible) is not a problem. Including short rotation/annual ryegrass in a permanent pasture seed mix is not recommended. The shorter term ryegrass tends to die out, allowing weeds to take over. >> View Catalogue


Perennial Ryegrass

Throughout the temperate zone world-wide, perennial ryegrass is the grass of choice where rainfall is reasonable and there are no extremes. In New Zealand, perennial ryegrass is our most widely used grass for grazing systems. It establishes rapidly, tolerates a range of management practices, and has high nutritive value.

Most perennial ryegrasses are available in "high" or "without" endophyte options, and recently new "safe" endophyte have become available. Endophyte can assist plant survival but may cause stock health problems. >> View Catalogue
