Effects of Irrigation and Planting Geometry on Soybean (Glycine max L.) Seed Nutrition in Humid Climates

Table 6

Effect of irrigation treatments (FI, HI, and RF) and PG (SR and TR planting) on soybean seed amino acids: aspartic acid (ASP), threonine (THR), serine (SER), and glutamic (GLU), proline (PRO), glycine (GLY), alanine (ALA), cystine (CYS), valine (VAL), methionine (MET), isoleucine (ISO), leucine (LEU), tyrosine (TYR), phenylalanine (PHE), and lysine (LYC).
