Summary: The study found that the application of glyphosate (2592 g a.i. ha(-1)) and the sequential application of glyphosate can result in higher levels of intoxication. However, the combination of B. subtilis BV02 with glyphosate (2592 g a.i. ha(-1)) can prevent losses in relative chlorophyll a and b values and the total chlorophyll index. Soybean yield is reduced when plants are subjected to a sequential application of glyphosate.

Summary: Estimates and explanations of yield gaps enable increased crop production through improvements in agricultural systems and crop management. This study aimed to break down the soybean yield gap in Rio Grande do Sul, Brazil and assess the impact of various factors. Through the use of field data and crop modeling, the researchers identified gaps in yield related to cultivar choice, sowing time, water availability, and management practices. Adjustments in management practices such as cultivar selection, sowing date, and fertilization can close a significant portion of the yield gap.

Summary: The nutritional status of plants plays a crucial role in soybean resistance against Asian soybean rust (ASR). Nickel (Ni) and glyphosate (Gl) have been reported to have beneficial effects on ASR control. This study investigated the effects of Ni, Gl, and their combination on defense mechanisms and antioxidative metabolism of soybean plants infected by Phakopsora pachyrhizi. The results showed that Ni and Gl significantly reduced the severity of ASR. Ni enhanced defense mechanisms, while Gl had limited impact on host defense responses.

Summary: The impact of fall-winter crop species on subsequent soybean performance under a no-tillage system in tropical environments was evaluated. Preceding cultivation of crambe or sunflower favored nutrient uptake by soybean, and sorghum, safflower, and crambe as fall-winter crops increased soybean yield compared to fallow plots. Maize and sunflower had the highest increases in soybean yield in the second and third growing seasons, respectively.

Summary: This study analyzed the proteomic profiles of GM soybean varieties under glyphosate spraying and water deficit conditions, revealing an increased metabolic cost and an imbalance in energy demand and production. Alterations in the ribosome pathway indicate a metabolic burden associated with genetic transformation in GM plants.

Summary: Global demand for soybean and its products has led to research on improving yields and tolerance to drought and disease. Metabolomics is becoming a powerful tool in plant breeding, helping in the development of high-performing cultivars with desirable traits. The combination of chromatography and mass spectrometry is particularly efficient for metabolomic studies, but other techniques like NMR and FTIR also have their benefits. Multivariate analysis allows for the identification and differentiation of various groups of soybean varieties.

Summary: In a winter wheat-fallow rotation cropping system, replacing a portion of the long fallow period with short-season cover crops can improve soil water use efficiency and productivity, with winter triticale or winter legume-triticale mixtures performing the best. Cover crops left standing store more soil water than hayed cover crops, and forage use of the cover crop could provide dual purposes and economic benefits to enhance overall system profitability.

Summary: Research shows that the activity of rotation-resistant beetles in soybean is influenced by specific proteinases and an adapted gut microbiota, providing limited protection against soybean defenses. The impact of soybean and corn herbivory on rotation-resistant female survival and flight initiation was investigated through mortality assays and wind tunnel flight tests.

Summary: Integrating oats as a cover crop in forage crops and their intercrops can effectively suppress weeds and enhance the quality and productivity of crops. The intercropping system with pea, Sudan grass, and barley showed the best performance. This finding is significant for weed control, improving forage quality, and increasing crop yields.

Summary: This study coupled a well-known crop model with a land surface model and evaluated the model performance using comprehensive data from soybean agroecosystems in eastern Nebraska. The results show that the coupled model can accurately simulate surface fluxes and crop performance, with simulated yields consistent with field observations.

Summary: This study evaluates the impact of El Nin & SIM;o-Southern Oscillation (ENSO) on soybean yield variability in the Southeastern US. The results suggest that adjusting soybean sowing dates according to ENSO phases can minimize the effects of extreme weather events (EWE) and reduce yield variability.

Summary: This study conducted a survey of soybean entomologists in 31 U.S. states to generate a contemporary assessment of the distribution and population persistence of lepidopteran soybean pests. The results highlighted clear differences in geographic distribution and relative persistence of lepidopteran pests in soybean, providing important contemporary distributions and persistence estimates for further research. The study also emphasized the need to improve IPM adoption in some states based on assessments of scouting practices.

Summary: Glyphosate and glyphosate-based herbicides have adverse effects on nervous system function, including increased risk of Parkinson's disease and autism, impaired synaptic transmission through mechanisms such as oxidative stress and mitochondrial dysfunction. In addition, glyphosate-based herbicides alter the gut microbiome, which in turn affects susceptibility to neurological diseases.

Summary: Soybean mosaic disease caused by soybean mosaic virus (SMV) results in significant losses in yield and seed quality worldwide. This study evaluated the phytotoxicity of Achyrocline satureioides extract and essential oils of Minthostachys verticillata, Origanum vulgare, and Thymus vulgaris on soybean. The results showed that all concentrations tested were safe, and two essential oils inhibited the production of viral antigens, indicating potential for developing an effective biopesticide against SMV.

Summary: This study evaluated the impact of increasing densities of Commelina benghalensis on the initial growth of Eucalyptus grandis plants, finding that a density of 4 plants/m(-2) negatively affected eucalyptus growth with significant reductions in leaf area and dry mass. The weed exhibited a more aggressive competitive behavior in summer, causing greater interference with eucalyptus growth.

Summary: The selectivity of herbicides and the use of adjuvants for the cultivation of Physalis angulata were evaluated in this study. It was found that the herbicides clethodim without adjuvant and fluazifop-p-butyl are selective for P. angulata crop, while metribuzin is not suitable for this crop. Under field conditions, the application of fluazifop-p-butyl + fomesafen did not negatively affect crop production and growth, being selective to P. angulata.
