Comparison of four high-yielding barley varieties under different water regimes – Condobolin 2017

Abstract

Key findings • • Under the low rainfall conditions in 2017, there was no competitive advantage of newer barley varieties over the benchmark variety La Trobe[PBR]. • • Newer varieties such as Rosalind[PBR], Compass[PBR] and RGT Planet[PBR] demonstrate a yield advantage in higher rainfall environments over La Trobe[PBR]. • • Under low rainfall conditions, La Trobe[PBR] demonstrates superior retention and screenings compared with newer barley varieties. • • Feed variety Rosalind[PBR] demonstrated excellent yield stability over a number of simulated rainfall scenarios.
