Abstract

The amino acid composition of samples of Irish-grown barley has been investigated using an auto matic analyser. The application of nitrogenous fertiliser (46 lb nitrogen/acre) at the time of sowing significantly increased the crude protein content of barley (variety Proctor) by 2.0 percent (p<0.01) without appreciably altering its amino acid composition. Levels of individual acids varied widely among barley samples with crude protein contents ranging from 6.5 to 12.9 percent. Significant relationships between the amino acids and crude protein content were found for aspartic and glutamic acids, glycine, tyrosine and threonine.
