Summary The effect of nitrogen applications on the amino acid composition of wheat grain was studied in a pot experiment, in which spring wheat was supplied with increasing amounts of ammonium sulphate. The ensuing yield curve extended from very small N-applications to applications resulting in a toxic effect on the yield. The contents of dry matter, total N, 15 amino acids and ammonia were determined in samples taken from 9 representative treatments. The relationship between the yield of dry matter and the concentration in the dry matte rof the individual amino acids showed the same characteristic variations as those previously found for total N and for a number of plant nutrients. In accordance with the results cited in the literature, increasing applications of N caused an increase of glumatic acid and proline on a nitrogen basis, whereas lysine and arginine decreased.
