“…Similar effects on root growth parameters have been identified. For example, Delfim et al (2018) [23] reported that a high level of fertilization results in significant decreases in soybean root length, root surface area, root volume and root diameter compared with soybean receiving no N application. Saito et al (2014) [22] also found decreases in root length when soybean was supplied with additional N compared with no fertilizer.…”

“…It is not clear why the NV are more tolerant to high FR, but the inhibition of RTs in the MV and OV by a high FR may be related to the reduced above-ground photosynthesis resulting from the high N level. A large amount of fertilizer in soil inhibits root nodule numbers and nodule mass, thereby reducing N 2 fixation [23,42]. Gibson and Harper (1985) [43] pointed out that this inhibition is a homeostatic mechanism that may allow the plant to balance the cost of N 2 fixation with the need for N. The diminished ability to fix N 2 may result in the plant being N deficient [19], which would further impede leaf photosynthesis and the supply of photosynthetic products to belowground parts, ultimately impacting root growth.…”

“…The soybean root system is sensitive to changes in the amount of N fertilizer. Root morphological or physiological traits generally increase significantly under moderate N conditions [20,21], but as the N fertilizer application rate (FR) increases, soybean RTs are inhibited compared with no fertilizer conditions [22][23][24]. In general, very limited soybean genotypes have been used as experimental materials, leading to the lack of a comparative study on the responses of RTs of varieties having varied yield potentials to increasing N fertilizer levels.…”

Root traits (RTs) of soybean (Glycine max (L.) Merr.) that can be improved through long-term genetic breeding have been identified. However, whether resistance to environmental stresses can be enhanced and more detailed information on the relationships between RTs and seed yield remain unclear. Here, we used a pot-culture experiment with 13 varieties released in different years to investigate the changes in some RTs resulting from genetic breeding-based improvements. We determined whether RTs in different varieties respond to increasing fertilization rates (FRs) differently and quantified the contributions of RTs to seed yield variation among varieties. Decades of genetic selection have resulted in significant desired changes in RTs as well as the seed yield (per plant) under different FR conditions. The RT values of soybean receiving the 1.1 g pot−1 FR treatment increased significantly by 8.20%, 8.75% and 8.68%, whereas those receiving the 2.2 g pot−1 FR treatment decreased by 14.31%, 13.28% and 5.52%, for old, middle and new variety groups, respectively, compared with the no fertilizer treatment, indicating that the tolerance of root to fertilizer stress was enhanced. The results of artificial interference analysis showed that root length at the full bloom stage, root-to-shoot ratio at the full seed stage and root activity at the beginning maturity stage were the most important factors affecting seed yield, contributing approximately 54%, 58% and 59%, respectively, to seed yield variation. Overall, our work provides a theoretical basis for future breeding, suggesting a direct selection of soybean RTs to improve soybean yield.

Drought severely affects the growth and yield of soybean plants especially during the flowering period. To investigate the effect of 2-oxoglutarate (2OG) in combination with foliar nitrogen (N) at flowering stage on drought resistance and seed yield of soybean under drought stress. This experiment was conducted in 2021 and 2022 on drought-resistant variety (Hefeng 50) and drought-sensitive variety (Hefeng 43) soybean plants treated with foliar N (DS + N) and 2-oxoglutarate (DS + 2OG) at flowering stage under drought stress. The results showed that drought stress at flowering stage significantly increased leaf malonaldehyde (MDA) content and reduced soybean yield per plant. However, superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities were significantly increased by foliar N treatment, and 2-oxoglutarate synergistically with foliar N treatment (DS + N + 2OG) was more beneficial to plant photosynthesis. 2-oxoglutarate significantly enhanced plant N content, glutamine synthetase (GS) and glutamate synthase (GOGAT) activity. Furthermore, 2-oxoglutarate increased the accumulation of proline and soluble sugars under drought stress. Under drought stress, soybean seed yield was increased by DS + N + 2OG treatment by 16.48–17.10% and 14.96–18.84% in 2021 and 2022, respectively. Thus, the combination of foliar N and 2-oxoglutarate better mitigated the adverse effects of drought stress and could better compensate for the yield loss of soybean under drought stress.
