Annual, Italian and short rotation ryegrass varieties 2010


The annual and Italian ryegrasses play an important role in providing winter forage in areas where temperate perennial ryegrasses fail to persist.

Poor persistence of perennial ryegrass occurs on the NSW Slopes and Tablelands due to low rainfall and soil acidity.

On the far north coast of NSW and in the irrigation areas of southern NSW, perennial ryegrass is unable to persist because of high summer temperatures and competition from tropical grasses.

This Primefact discusses plant types, maturity times, rust susceptibility, diploid/tetraploid differences, sowing rates, feed quality, animal health issues and seed differences.
