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 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 aimed to investigate the effects of foliar spraying with different sources of silicon on soybean, cotton, and maize. The results showed that all sources of silicon increased leaf silicon concentration, photosynthetic parameters, and yield. Stabilized potassium silicate was found to be a good alternative to conventional potassium silicate for fertilizing crops. It is recommended to spray silicon at a concentration between 0.6 and 0.8 g L-1 when the leaf silicon content is below a certain threshold.

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: Edamame is an important economic crop worldwide with high water requirements during development stages. Under drought conditions, KH11 and XJ showed better drought resistance compared to KH9, possibly due to upregulation of genes involved in ABA biosynthesis pathways. Different drought-related signaling transductions among these cultivars led to varying levels of drought tolerance.

Summary: In order to reduce the import of genetically modified soybean meal, both Europe and Poland are committed to increasing the production of their own fodder protein. The climate in central Europe and advancements in breeding have allowed for the growth of soybeans in this region. The use of biostimulants can enhance the yield potential of plants, including soybeans. The objective of this study was to evaluate the yield of three non-GMO soybean cultivars treated with biostimulants under the climatic conditions of central-eastern Poland.

Summary: The study evaluated the effectiveness of applying the commercial mixture trifloxystrobin + prothioconazole at different spray volumes on soybean plants to control rust. It was found that increasing spray volume provided greater leaf coverage but had no effect on rust control or yield. The commercial mixture can control rust at spray volumes as low as 50 L ha-1 under favorable environmental conditions.

Summary: Soybean plays a critical role in global food security and sustainability, but the interaction between soil nitrogen supply and nitrogen fixation throughout the growing season is poorly understood. This study evaluated the relationship between nitrogen uptake and dry matter, described seasonal changes in soil-plant nitrogen dynamics among genotypes with different genetic backgrounds, and assessed the influence of soil NO3 and NH4 on temporal nitrogen fixation changes. The findings showed that nitrogen uptake from the soil had a greater impact on total nitrogen status than fixation. NH4 exposure and delayed NO3 availability suppressed end-season nitrogen fixation, highlighting the importance of soil nitrogen sources in soybean growth.

Summary: A study conducted in soybean fields in Brazil found that temperature has an impact on the population growth of B. tabaci and crop yield. Higher temperatures promote faster growth and an additional generation of the pest, but have a negative effect on crop yield and quality.

Summary: Soybean seedlings can accumulate high concentrations of lead in their organs, but generally do not show morpho-physiological lead stress symptoms except for lipid peroxidation and antioxidant power. Treatment with calcium ions did not effectively reduce lead entry into the roots, and altering the transpiration rate showed that lead accumulation was lower in seedlings exposed to air flow, indicating selective exclusion of the metal in the solution. Overall, soybean seedlings demonstrated tolerance to high lead concentrations.

Summary: Ideotype breeding is a strategy that models traits and introduces them into a model or crop species to assess their impact on yield. Understanding the connection between genotype and phenotype is essential for successful ideotype breeding. Advancements in genome engineering tools, transformation efficiency, and genotyping techniques enable the widespread adoption of ideotype breeding to complement conventional breeding. This approach, coupled with biotechnological tools, can contribute to knowledge-based legume breeding and accelerate yield gains for food security.

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: 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: The use of desiccants such as saflufenacil and flumioxazin can help anticipate cowpea harvest and improve seed quality. Saflufenacil application can compromise yield components and technological quality, while flumioxazin application does not affect yield components. Storage for six months at 20 degrees C decreases the physiological quality of seeds. Flumioxazin application at cowpea harvest can promote maturity uniformity and harvest anticipation without affecting post-harvest physiological quality.

Summary: The study aimed to evaluate the effects of foliar application of potassium nitrate (KNO3) on water deficit tolerance in sorghum plants before flowering. The results showed that foliar application of KNO3 increased photosynthetic rate, stomatal conductance, and chlorophyll content, and enhanced the concentrations of several elements in the leaves. Under water deficit conditions, plants treated with KNO3 showed improved growth and higher yield.

Summary: The study evaluated the effect of glyphosate on Hymenaea courbaril. While glyphosate did not affect the visual and anatomical structures of the plant, it did have a positive impact on photosynthesis and transpiration. Plant growth increased at lower glyphosate doses but the number of leaves decreased as the dose increased.
