Effect of nitrogen fertilization on metabolisms of essential and non-essential amino acids in field-grown grain maize (Zea mays L.)
In Boys Hat two-year field experiments, nitrogen (N) in the form of urea (0, 120 and 240 kg N/ha) was applied to grain maize (Zea mays L.) hybrid KWS 2376.The two-year mean content of total grain N at harvest was 1.54%.The highest N dose reduced most of the 17 amino acids (AA) analysed in the grain compared with the other treatments.Possible reason
