Influence of plant population and nitrogen timing on canopy structure, yield potential and quality on malting barley cv Gairdner locations
Aims

This trial is part of larger GRDC funded project, which examines whether lower plant populations and later timed nitrogen approaches are suited to the HRZ in Australia, it also examines whether these techniques which were principally established for wheat can be used in malting barley, where high protein can be undesirable.

Key messages

The work illustrated that in low fertility situations, which are more ideal for malting barley (2nd cereal low soil N reserves), there was no disadvantage to applying nitrogen applications at stem elongation (GS30-33).
