Role of nitrogen and dry matter partitioning in determining the quality of malting barley

Abstract Variation in quality of grain for malting is caused by a complex set of interacting factors during the growth of the crop. Poor quality grain resulting from high screening percentage, high nitrogen (N) concentrations, or low malt extract levels occur particularly when soil conditions are dry during grain filling or if soil N management is inappropriate for dryland conditions. Commercial and experimental malting barley crops (Hordeum vulgare L. ‘Triumph') were monitored over three seasons to determine if the variation in quality could be explained by differences in the pattern of partitioning of crop dry matter (DM) and N accumulation. Screenings, grain N content, malt extract, and indicators of malt modification were strongly influenced by total crop N yield or crop N concentration at anthesis. The level of mobilisation of N reserves to the grain during grain filling was also correlated with grain and malt quality, whereas the level of post‐anthesis N uptake had little effect. The best opportunit...
