To examine tailoring barley plant density to specific varieties in order to maximise yield and quality
• In the unusually wet growing season of 2016, increasing the barley plant density did not increase the yield of all varieties.
• High tiller numbers reduced overall grain size.
• In ideal growing conditions, some varieties with lower plant densities of <125 plants/m2 out-yielded higher density treatments.
Randomised complete block design, varieties and seed rates randomised within three replicates
