Summary: The relationship between soybean and Bradyrhizobium japonicum provides the majority of nitrogen required for the crop, but supplemental nitrogen studies and co-inoculation with Azospirillum are necessary to investigate higher yields. This study evaluated the effects of nitrogen rates and inoculation on nodulation and found that excessive nitrogen inhibited nodulation. Co-inoculation increased the number and volume of nodules, but did not significantly improve yield compared to inoculation with B. japonicum.

Summary: The study aims to verify the effect of bacterial inoculation and compare it with different mineral nitrogen fertilization on soybean in south-eastern Poland. The results showed that inoculation with B. japonicum increased nodulation, yield components, and seed yield, but had no significant effect on seed yield. The application of 30 kg N .ha (-1) fertilizer did not result in a significant reduction in the number and weight of nodules compared to seeds inoculated and not fertilized with nitrogen.

Summary: The study found that the base of the stem in soybean plants is a reliable fraction for quantifying ureide abundance, while the ureide content in upper leaflets is poorly correlated with values in the main stem. Additionally, the RAU trends in the upper petiole are similar to those in the base of the stem, but do not provide reliable RAU estimates.

Summary: In Mediterranean cropping systems, sustainable nitrogen management requires practices to be specifically adapted to the local agro-environmental characteristics, with a special emphasis on water availability for rainfed and irrigated systems. This approach should also include a systemic analysis of nitrogen input into the territory driven by the configuration of the agro-food system.

Summary: This study investigated the effects of fertilization on soybean yield in arid areas under a drip irrigation system. The results showed that nitrogen fertilizer had the greatest impact on grain yield, while phosphorus and potassium fertilizers influenced other growth traits. The optimal fertilizer combination for high yield and quality was determined using quadratic polynomial regression analysis. The findings provide guidance for effective fertilizer application and promoting large-scale cultivation of soybean under drip irrigation.

Summary: Algae extract biostimulants can enhance nutrient uptake, stress tolerance, and productivity in various crops. This study aimed to investigate the effect of a commercial Ascophyllum nodosum algae extract on nitrogen metabolism and productivity in nodulating soybean plants. The results showed that the application of algae extract increased leaf and stem biomass, pod and seed number and weight, and overall productivity. Biochemical analysis revealed an increase in amino acid content in leaves after extract application. Principal component analysis and gene expression heatmaps supported the conclusion that algae extract application affected nitrogen metabolism and led to higher seed production.

Summary: The study found that straw returning significantly increased soil fertility, enzyme activities, and microbial community diversity, particularly in bacterial and fungal communities. In contrast, nitrogen fertilizer application increased soil fertility and enzyme activities but decreased the richness of bacterial and fungal communities.

Summary: Seed storage compound deposition is influenced by maternal and filial tissues. This study investigated the strategies employed during soybean embryo development and filling, using in vitro culture systems and metabolomics and proteomics approaches. The carbon:nitrogen ratio (C:N) and abscisic acid (ABA) were found to be specific and interacting signals that induced metabolic reprogramming and changes in storage macromolecule accumulation. The results provide valuable insights for improving oil and protein yields, with implications for nutrition and green chemistry.

Summary: Imprecise irrigation hinders the sustainable development of the fruit tree-crop intercropping system in the Loess Gully Area of China. Drip fertigation was applied for two years as part of an apple-soybean intercropping system to optimize local water and nutrient management patterns. The effects of different drip irrigation and fertilizer levels on photosynthetic characteristics, soil nutrients, and their interspecific competitions were studied. The results indicate that a combination of irrigation at 80% of field capacity and 92 kg.ha(-1) nitrogen fertilizer application is optimal for the system.

Summary: Soil organic matter plays a crucial role in soil quality. In sandy soils, high biological activity accelerates mineralization and restricts the increase of organic matter content. This study shows that cover cropping can significantly increase the content of various fractions of organic matter in a short period, and a mixture of cover crops is the best option.

Summary: The use of thiamethoxam and the ripener sulfometuron-methyl can significantly increase the yield and sucrose content of sugarcane. Thiamethoxam, as a bioactivator, promotes new stalk and leaf growth, leading to higher biomass production. Applying both thiamethoxam and sulfometuron-methyl can achieve better results simultaneously.

Summary: Recent advances in biotechnology make it possible to obtain glyphosate-resistant corn genotypes, allowing for large-scale usage of this herbicide. However, the use of glyphosate can exacerbate water deficit effects during the initial development of crops. This study aimed to investigate the physiological and biochemical effects of glyphosate on glyphosate-resistant (RR) corn plants under water deficit conditions. Our results show that glyphosate application does not negatively impact RR corn plants under moderate water deficit but negatively affects root length and volume in the absence of water deficit.

Summary: Soil aggregation is a critical indicator for assessing soil health and its role in protecting against erosion, storing organic carbon, and supporting soil organisms. The choice of initial sieve opening size impacts the determination of dry-stable and water-stable mean-weight diameter (MWD) in fine-textured soils. While initial sieving through 8 mm resulted in higher dry-stable MWD, the soil stability index was not affected by the sieve size. Both methods provided consistent interpretations of soil management practices and demonstrated the depth effect on water-stable MWD. The study suggests that using a 4.75-mm sieve opening for soil analysis can provide reasonable estimates and interpretations of surface soil aggregation.

Summary: Soil management systems have a direct impact on the relationship between soil and plants, but there is limited research on the influence of long-term management systems on the physiological quality of soybean seeds. The effects of pre-harvest desiccation on seed quality, particularly seed longevity, are also not well understood. This study aimed to evaluate the physiological quality of soybean seeds grown under conventional tillage and no-tillage systems, with and without the use of desiccants. Overall, seeds cultivated under conventional tillage showed higher vigor, while the no-tillage system had superior seed longevity. However, the application of desiccants reduced seed longevity in both systems.

Summary: Herbicides with desiccant actions can be used to anticipate soybean seed harvesting, but they may compromise the acquisition of seed quality components, especially longevity. This research aimed to evaluate the physiological quality of soybean seeds subjected to forced maturation with desiccants. The results indicate that the application of herbicide with desiccant action interrupts the process of acquiring seed physiological quality, especially longevity in soybean seeds.
