Trial details

Aims

To evaluate how new and existing wheat and barley varieties respond to grazing and post-grazing nitrogen (N) application rates.

Key messages
  • Grazed crops showed no effects from grazing in 2016 – an excellent season producing high early biomass. Crops recovered and yielded very well.
  • Trojan and LRPB Arrow were the best dual purpose wheat varieties.
  • Fathom, Spartacus and Rosalind were the best dual purpose barley varieties.
