The effects of filling pods on the production and partitioning of nonstructural carbohydrates (NSC) were determined in field‐grown ‘Clay’ soybeans ( Glycine max (L.) Merr.) by periodically sampling the NSC concentrations in stems, leaflets and petioles of control and depodded plants from flowering to maturity. Rates of dry matter accumulation were greater in control plants than in depodded plants, but total dry matter accumulation at the time of pod maturity was similar in control and depodded plants, primarily because the depodded plants did not drop their leaves. Concentrations of NSC in stems, leaflets, and petioles remained fairly constant in control plants, but all increased markedly in depodded plants, primarily due to starch accumulation. Leaflets and especially petioles in the upper part of the canopy were major sites of starch storage in depodded plants.
