A field experiment was conducted at Dirnaseer in 2021 to evaluate the differences between wheat and barley for phenology, grain yield and quality in response to sowing time. This paper presents the results and discusses the influence of sowing date on the phenology, grain yield and quality for 24 wheat and 12 barley varieties.
• Mild temperatures, combined with unlimited soil moisture through the season provided optimal conditions for crop growth and development, resulting in very high grain yields in 2021.
• There were significant differences in grain yield responses across sowing dates, with many newly released wheat and barley genotypes achieving higher grain yields compared with current industry benchmarks.
• The barley genotypes flowering window was 15 days earlier compared with the wheat genotypes; barley had higher yields than wheat at comparable flowering dates.
• Rain, combined with cool temperatures during the grain filling stages, had a significant effect on grain quality. There were significant genotype × sowing date interactions, with earlier sowing treatments recording lower falling numbers compared with the late
May sowing.
