The effect of nitrogen, plant growth regulator and variety on yield in autumn sown oats

The poster presented a research study that investigated how nitrogen application rates, plant growth regulators (PGR), and oat varieties affected grain yield and quality in autumn-sown oats. It outlined the importance of oats as a high-value, nutritious crop with increasing market demand and emphasized the need to optimize management practices. Using a split-plot experimental design with three oat varieties (Husky, Barra, Isabel) and varying nitrogen levels, the study measured yield and grain quality through field trials. The results, shown in the graphs on the right side of the poster, indicated that higher nitrogen rates significantly increased yield, with the best performance at 150–180 kg/ha, while PGR had little effect. Variety played a key role, with Husky producing the highest yields and Barra the lowest, and also influencing grain screenings. The poster concluded that these were preliminary findings from ongoing multi-year trials aimed at improving oat production guidelines
