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

Table 7

Effect of irrigation treatments (FI, HI, and RF) and PG (SR and TR planting) on soybean seed amino acids: methionine (MET), isoleucine (ISO), leucine (LEU), tyrosine (TYR), phenylalanine (PHE), lysine (LYS), histidine (HIS), arginine (ARG), and tryptophan (TRY) (%).
