Comparison of the two varieties DBA Vittaroi and DBA Aurora under various N, PGR and sowing rates
DBA Vittaroi had higher grain protein than DBA Aurora under similar N management
Both varieties lodged where a PGR was not applied
Sowing rate did not affect yield or grains per head.
Graind per head averaged 2.1g or 2.1 t/ha per 100 heads/m2
