Dual-purpose oat evaluation, Tamworth 2020

Abstract

Key findings • Varieties differed in the amount of dry matter (DM) produced at stem elongation (growth stage 30; GS30) and in response to sowing date. • Sowing date two (SD2) sown on 2 April, produced the highest grain yield responses following grazing at GS30. • All varieties suffered yield penalties when sown early, SD1 sown on 13 March, versus SD2. • Some varieties had significant yield increases in response to grazing due to reduced lodging. • Varieties differed in their ability to achieve grain receival standards. The combination of rainfall and inherently inferior grain quality resulted in downgrading due to low test weight and/or high screenings.
