Yield and grain quality response of barley cultivars to four sowing dates – Narrabri 2014

Abstract

Key findings • This time of sowing trial highlighted the ability of some of the newer barley varieties namely Compass [PBR] and Fathom [PBR] to maintain grain yield (GY) and grain quality parameters across a relatively wide sowing window. • Results illustrated the benefit of sowing in the early part of the sowing window, particularly for the longer season varieties Navigator [PBR] and Oxford [PBR], which showed significant decreases in GY and quality (increased screenings/ decreased retentions) with delayed sowings. • GrangeR [PBR] and Compass [PBR], showed improved grain retentions and grain stability in comparison to Gairdner [PBR] and Commander [PBR] respectively, highlighting the breeding improvements in terms of GY and quality, of the newer malt and or potential malt varieties. • NRB121156, an advanced breeders line, showed good grain stability and displayed excellent straw strength across sowing dates.
