Remote Sensing, Год журнала: 2025, Номер 17(4), С. 690 - 690

The breeding of high-yield varieties is a core objective soybean programs, and phenotypic trait-based selection offers an effective pathway to achieve this goal. aim study was identify the key traits utilize these for screening varieties. In study, UAV (unmanned aerial vehicle)- field-based data were collected from 1923 1015 plots at Xuzhou experimental site in 2022 2023, respectively. First, grouped by using self-organizing map K-means clustering investigate relationships between various yield ones selecting It shown that duration canopy coverage remaining above 90% (Tcc90) critical trait Moreover, typically exhibited several such as rapid development (Tcc90r, time when first reached 90%), prolonged high (Tcc90), delayed decline (Tcc90d, began below moderate-to-high plant height (PH) hundred-grain weight (HGW). Based on findings, method proposed, through which 87% 72% (top 5%) respectively, successfully selected. Additionally, about 9% (in 2022) 10% 2023) low-yielding (bottom 60%) misclassified high-yielding. This demonstrates benefit high-throughput phenotyping yield-related variety provides helpful insights into identifying programs.

Analysis of the Synergistic Effect of Endophytic Bacteria and Metabolites on Yield in Soybean Roots Under Biochar with Nitrogen Fertilization

Agronomy, Год журнала: 2025, Номер 15(1), С. 177 - 177

Опубликована: Янв. 13, 2025

The appropriate application of nitrogen fertilizers and biochar to the soil is beneficial for soybean growth, a combination can improve low-nitrogen fertilizer utilization efficiency. However, effect on roots still unclear. Therefore, in this study, we investigate changes endophytic bacterial communities metabolites under different combinations treatments by setting fertilization levels using high-throughput sequencing non-targeted metabolomics techniques. results showed that applying 20 t/ha 180 kg/ha (C2N1) resulted highest yield. By studying community roots, it was observed dominant phyla were Proteobacteria, Bacteroidota, Actinobacteriota, genera Bradyrhizobium, Streptomyces, Rhizobacter. Moreover, metabolic pathway analysis revealed glycosylphosphatidylinositol (GPI)-anchor biosynthesis most significant C0N1 vs. C0N0 comparison group, glycerophospholipid metabolism C2N1 C1N1 group; they both associated with regulatory mechanisms such as plant growth promotion nutrient cycling. Structural equation modeling indicates bacteria have positive impact Bradyrhizobium Rhizobium are observable variables effects bacteria, while Phe-Thr 7-allyloxycoumarin metabolites. Endophytic not only direct crop yield, but also indirectly affect yield through their This study has important scientific value guiding significance improving yields.

Enhancing soybean productivity through agroforestry, organic waste fertilization, and mulching: A review about climate change

BIO Web of Conferences, Год журнала: 2025, Номер 155, С. 01021 - 01021

Опубликована: Янв. 1, 2025

Some issues that will threaten agriculture now and in the future are declining productivity increased risks due to climate change. However, agroforestry, organic waste fertilizers, mulching promising ways address these challenges. They offer approaches increase improve land adaptability extremes. This review explores integration of fertilizer from local systems as strategies soybean while ensuring sustainability. Agroforestry reduced soil erosion by 50% carbon stocks 26-34% at various depths. Organic fertilizers combined with inorganic inputs yields 12.8-32.5%, further 38.6-44.2%. These practices health, reduce reliance on chemical provide ecosystem services support adaptation mitigation for combination is expected production meet global demand. adoption remains limited economic technical constraints, particularly among smallholder farmers. Future studies should cost-effective solutions identify optimal zones implementation.
