Grain and Graze 3 - Grazing crops and frost locations

The trial aims to see the benefits of crop grazing at various times of sowing, to increase feed availability for stock, while retaining winter pastures and to find out whether crop grazing can be utilised in delaying the flowering window to reduce the impact of frost. It also aims to assess the impact of grazing times against the grain yield and quality across various species and varieties.

Key messages

In summary, the TOS1 showed a greater variance overall between grazing treatments and the frost events of 2016 seemed to have a greater impact on this section of the trial. Results from TOS2 did not vary greatly between treatments and the effects of frost damage were not as prevalent. This indicates that grazing early sown cereals can have a great effect on yields and provide an excellent source of feed to livestock and the grazing of later sown crops in a season like 2016 does not impact yields or quality
