Oat agronomy trial report (variety agronomy) locations

This trial is the second year of the trial series comparing the performance and response of two breeding lines (03198-18, named Kowari, and 06204-16, named Bilby) and two benchmark varieties (Carrolup and Williams) to changes in nitrogen and plant density in medium rainfall environments.

Key messages

 New variety Bilby  (breeding line 06204-16) out-yielded Carrolup (by 0.7 t/ha), but did not out-yield Williams , and had lower grain quality than Carrolup in grain quality. 

Similar to 2017, a mild finish to the growing season meant all varieties met Oat1 quality specifications, and agronomy had a reduced impact on grain quality.
