Local growers report a yield ceiling in oats, unlike barley, suggesting a challenge in achieving higher grain yield. This may stem from higher biomass and a source-sink imbalance, making oats more vulnerable to environmental stress. Last season’s trials support this, showing excessive nitrogen reduced harvest index and grain weight, ultimately lowering yields—likely due to increased biomass and greater susceptibility to terminal drought.
