Summary: This study aimed to estimate nutrient absorption rate in soybean plants grown in succession to cover crops and under different soil management systems. The experiments were conducted over two cropping years using soybean plants grown on the remaining straw of Crotalaria spectabilis and Pennisetum glaucum (millet) under no-tillage and minimum tillage. The results showed that soybean yield was higher in the minimum tillage system, and the accumulation of nutrients and dry matter in soybean plants grown on millet and C. spectabilis straw were similar across different soil management systems. The highest accumulation of nutrients and dry matter in soybean occurred between stages R5 and R7, and most nutrients were allocated to the grains during physiological maturity.

Summary: Hydrogen sulfide (H2S) is a gas signaling molecule that plays a crucial role in plant growth and stress response. In this study, we investigated the effects of H2S and rhizobia on nutrient transport and utilization in legume-rhizobia symbiosis systems. Our results showed that the application of H2S and rhizobia improved plant phenotypes, biomass accumulation, and nutrient content in different organs of soybean. Furthermore, H2S and rhizobia significantly affected grain nutrient harvest and overall plant nutrient accumulation. These findings highlight the importance of H2S in optimizing grain harvest quality and nutrient accumulation in soybean.

Summary: Folate deficiency is a major global health issue that affects millions of people and has severe adverse effects. Staple crops often have inadequate folate levels, and synthetic fortification has helped reduce low-folate populations but is not a sustainable solution. Biofortification, through breeding crops to naturally increase their nutrient content, is a promising alternative. Soybean, a highly nutritious crop, can be a good candidate for folate biofortification, but there have been limited studies on folate due to analytical challenges.

Summary: Late or early sowing can simulate the effects of climate change, which is a critical issue in agriculture. The rise in temperature exposes crops to heat stress, resulting in reduced productivity. Scientists evaluated the performance of soybean genotypes under different sowing dates and found that certain genotypes showed higher catalase activity and leaf area, as well as improved seed yield and oil content under specific sowing conditions.

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: Aerosols can contribute to plant nutrition via foliar uptake, especially at night when humidity is high. Although stomata tend to be closed at night, plants can benefit from nocturnal stomatal opening to increase humidity and facilitate nutrient uptake. This hypothesis was supported by experiments on P-deficient soil.

Summary: Micro and nanoplastics are new generation contaminants of global concern. By conducting a hydroponic experiment on soybean seedlings, this study found that polystyrene nanoplastics (PS-NPs) negatively affected the growth parameters of soybean seedlings and caused oxidative stress. Additionally, the levels of antioxidant enzymes and proline content in roots and leaves of soybean were enhanced, and stress-related genes were up-regulated in a tissue specific manner in response to PS-NPs. These findings suggest that PS-NPs have adverse effects on soybean seedlings, which are important for the risk assessment of nanoplastics on crop production and environmental safety.

Summary: Trace element deficiency is a global issue causing malnutrition, primarily due to low intake of essential trace elements in diets, which is prevalent in many regions worldwide. Fortifying staple crops with vital trace elements has emerged as a viable solution, with addition methods including chemical amendments, genetic breeding, transgenic approaches, and the use of soil-beneficial microbes. Plant growth-promoting microbes are a subset of beneficial soil microbes that can enhance the transport of essential minerals into plants, potentially improving the nutritional quality of crops. Further research is needed to fully understand the molecular mechanisms involved and develop customized bioinoculants for combating trace element deficiency and promoting global nutritional well-being.

Summary: The joint application of phosphorus (P) and ammonium (N-NH4+) has been shown to increase maize root proliferation and P acquisition in alkaline soils. This study aimed to assess the effect of the joint application of P and N-NH4+ on soybean root growth and P acquisition. The results showed that P fertilization increased the soil P content, decreased the rhizosphere pH, and resulted in increased soybean P uptake and use efficiency.

Summary: Soil acidity is a major factor affecting crop productivity, especially in combination with dry spells. Surface liming can alleviate soil acidity, improve root growth, enhance photosynthetic activity, and increase crop yield. Increasing lime rates up to 2 times the recommended rate boosts soil fertility, root growth, and soybean photosynthetic metabolism, leading to improved growth and yield even under dry spell conditions.

Summary: The study found that applying lime combined with phosphogypsum in tropical no-till systems can improve soil fertility, enhance soybean root growth, and increase plant nutrition and physiological responses, resulting in improved crop resistance to dry spells. These long-term soil amendments also increased the movement of cationic bases and roots in the soil profile, improving soybean nutrition. Moreover, the application of lime and phosphogypsum enhanced carbon and antioxidant metabolism in soybean plants, leading to higher grain yield despite the occurrence of dry spells in the tropical region.

Summary: This study evaluated the effects of irrigation, semi-protected cultivation, and artificial pollination on the yield and quality of organic yellow passion fruit. The results showed that artificial pollination significantly increased the fruit yield, while irrigation and semi-protected cultivation did not affect the yield or number of fruits per plant. There was a positive linear relationship between the number of fruits and the yield. Regardless of irrigation, using a combination of semi-protected cultivation, rainfed conditions, and artificial pollination or direct sunlight and natural pollination resulted in higher mean fruit mass.
