NE, E, and SE stand for non-essential, essential and semi-essential amino acids, respectively. CM and IMS stand for conventional management practice and integrated management strategies (see Materials and Methods). The unit of proteinogenic amino acids is the percentage of dry mass. The means ± standard errors (n = 3) within each column followed by the same letter are significantly different (P < 0.05) according to Fisher’s least significant difference (LSD) test.
