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

Table 4

Effect of irrigation treatments (FI, HI, and RF) and PG (single-row (SR) and twin-row (TR) planting) on soybean seed protein: oil, palmitic (C16:0), stearic (C18:0), oleic (C18:1), linoleic (C18:2), linolenic (C18:3), and sugars (sucrose, raffinose, and stachyose).
