Soybean seed is composed of protein, oil, and residual. The residual fraction contains minerals, soluble and insoluble carbohydrates, and lignin. Carbohydrates in the residual fraction are rarely studied because of their low economic and nutritional value, but they can affect the performance and quality of derived protein ingredients. Our objective was to describe how genotypes (G) and environment (E) affect protein, oil, and soluble carbohydrates within the residual fraction of soybean seeds. We evaluated nine commercial genotypes in two environments with contrasting sowing dates (8 Nov. and 19 Dec., 2019) in Zavalla, Santa Fe. The late sowing environment had more protein and slightly less oil concentration, but no significant (p>0.05) variation was observed in the residual one. However, observed changes in these three traits were dependent on the specific genotype (significant GxE; p
