To determine if mixing cereal varieites with differing maturing will help reduce risk of crop failure in a moderate risk zone.
mixing varieties with different phenologies together can reduces frost risk/damage by allowing for multiple flowering windows that can avoid a frost at different times.

Other trial notes |
There is some anecodotal evidence to suggest that mixing varieties with differing phenology has the ability to he risk of crop failure from frost, however the benefit needs quanification and types of mixes need further exploration. Trial impacted by any unusual or adverse factors: Frost |
