Effect of seeding density and nitrogen rate on yield and quality of milling oat varieties – Wagga Wagga 2016 and Marrar 2017 locations
Aims

T evaluate the influence of seeding density and nitrogen (N) applied at sowing on plant establishment, phenology, grain yield and quality of four commercial milling oat varieties.
 

Key messages

• Yield responses to seeding density and nitrogen rate varied between the 2016 and 2017 seasons.

• BannisterA achieved the highest grain yields and had consistent grain quality in both years compared with other varieties.

• In 2017 the new milling variety KowariA had a yield advantage over benchmark variety MitikaA, and had a more stable grain quality at higher seeding and nitrogen rates.
