Summary: Pueraria montana var. lobata, originally from East Asia, has been introduced to many countries but unfortunately became a harmful weed species. It threatens the native flora and fauna, affects the concentration of carbon and nitrogen, and increases pollutants in the atmosphere. Its fast growth, thick canopy structure, and adaptability contribute to its invasiveness. This review article focuses on the invasive mechanisms of P. montana and its defense functions against natural enemies and pathogens.

Summary: Adaptation based on social resilience is proposed as an effective measure to mitigate hunger and avoid food shocks caused by climate change. This research examines the case of North Korea and its neighbors, South Korea and China, and finds that social resilience plays a crucial role in mitigating the adverse effects of climate change on food security and human hunger. While the effectiveness of social resilience in North Korea is not significant, it has shown significant contributions in the developed and developing regions of South Korea and China. These findings provide necessary quantitative information for addressing the negative impacts of climate change.

Summary: The study reveals that crop roots response varies under different soil moisture conditions, with some crops growing deeper roots under continuous waterlogging and gradual soil drying. Gradual soil drying tends to promote root and shoot biomass growth regardless of the crop species, showing that crop adaptation to different soil water conditions influences root distribution and biomass allocation.

Summary: Understanding the yield responses of different oil palm progenies to rainfall is crucial for effective plantation management. This study developed an alternative approach to evaluate oil palm yield responses to varying rainfall regimes by analyzing rainfall and yield data. The study identified the yield components most affected by rainfall fluctuations and determined the floral developmental stages susceptible to rainfall changes. It also compared the relative yield performance of different oil palm materials in different rainfall conditions to identify those adapted to low rainfall conditions.

Summary: Global climatic change poses an increasing threat to plant adaptation and crop yields. The plant circadian clock plays a crucial role in synchronizing internal biological processes with external environmental cues, thereby benefiting plant adaptation and yield. This review focuses on the interaction between the plant circadian clock and environmental factors, summarizing recent progress on how the circadian clock affects crop yield. Additionally, potential strategies for utilizing circadian biology in crop production are proposed.

Summary: Climate change has a significant impact on crop yield, with projected decreases in maize and increases in soybeans. Water stress currently limits crop yield in the Corn Belt, but heat stress will become a limiting factor after the midcentury. Climate change will offset some of the yield boost from agricultural technology and intensification, and multiple strategies will be needed to address the challenges it poses for U.S. agriculture.

Summary: Simulations of crop yield under climate change show significant variations depending on models, locations, species, management strategies, and Representative Concentration Pathways. A meta-model based on site-level simulations was developed to understand the effects of climate and adaptation on yield change for maize, rice, wheat, and soybean. The study found that adaptation plays a crucial role in mitigating projected yield losses under the RCP4.5 scenario, with most influential factors being adaptation strategy and climate change. These results highlight the importance of implementing adequate adaptation strategies to mitigate the impact of climate change on crop yields.

Summary: The influence of global climate change on agricultural productivity is an ongoing concern. A database of future crop yield changes was developed, which found that maximum temperature, precipitation, adaptation measures, study area, and climate model had significant effects on changes in crop yield. Higher CO2 concentrations and suitable management strategies could mitigate the negative effects of warming temperatures, and crop yield with adaptation measures increased significantly compared to crop yield without adaptation measures. The results can guide policy and adaptation plans for increasing crop systems' resilience in the future.

Summary: This study aims to reduce the use of inorganic nitrogen fertilizer in hydroponic common bean cultivation without compromising plant performance. The 50-25% mineral-N application regime showed significant increases in nodulation, biological nitrogen fixation (BNF), and yield, while the 75-25% regime during the vegetative stage resulted in yield losses due to restricted nodulation and BNF. Both rhizobia strains stimulated nodulation and BNF, but their capacity was suppressed as the inorganic-N input increased.

Summary: The aim of this study was to evaluate the impact of different nitrogen fertilization schemes on yield and quality of common beans grown organically or conventionally. The results showed that organic common beans treated with sheep manure and field beans as green manure produced smaller pods with higher dry matter and bioactive compound content, while conventionally grown common beans had higher yield. The different fertilization practices did not affect the sugar and starch content of the pods.

Summary: The horticultural sector is looking for innovative and sustainable agronomic practices to improve yield and product quality. Plant biofortification, specifically with iodine, is recognized as a valuable technique in enhancing microelement concentrations in plants. In this study, a seaweed extract-based biostimulant (SwE) and different levels of iodine were applied to tunnel-grown Savana strawberries, resulting in improved growth, yield, fruit quality, and nutrient content. The combination of SwE application and iodine biofortification increased the strawberry yield and quality, as well as enhanced the plant's nutritional status and iodine tolerance.

Summary: Soils with high lead levels can be decontaminated using tolerant plants, and the effectiveness can be enhanced by adding nitrogen to the soil. This study investigated the potential of purslane as a phytoremediation species by testing its growth in soil spiked with different doses of lead and with or without added nitrogen. The results showed that lead did not adversely affect plant growth and physiological parameters, and adding nitrogen improved the plant's biomass and growth. Lead concentration and uptake also increased significantly with added nitrogen, supporting our hypothesis. However, further research under field conditions is needed to confirm the potential of purslane as a phytoremediation species.

Summary: In this study, the chemical composition and bioactive properties of commercially available Withania somnifera samples were evaluated. The aqueous extracts showed higher polyphenols, ascorbic acid content, and antioxidant activity compared to the hydromethanolic extracts. On the other hand, the hydromethanolic extracts contained higher amounts of phenolic acids and flavonoids. Samples 4, 6, and 10 exhibited the best antibacterial activity against all tested strains, while the aqueous and hydromethanolic extracts showed the highest inhibitory activities against AChE and BChE, respectively.

Summary: Salinity is a major stress factor that affects vegetable production in semi-arid climates like the Mediterranean. Limited water availability, changes in rainfall patterns, and rising temperatures can lead to increased soil salinity. The extent to which crop yield is affected by salinity stress depends on the specific cultivar. Tomato landraces show genetic diversity and resilience to environmental stresses, making them valuable resources for breeding programs. In this study, the effects of mild salinity stress on sixteen Mediterranean tomato landraces were examined, and cherry-type landraces were found to be the most tolerant.

Summary: Water shortage can restrict the growth and quality of vegetable crops. This study found that regulated deficit irrigation and biostimulant application can improve the energetic value, carbohydrates, and free sugars content of processing tomatoes. However, the response of organic acids, tocopherols, and carotenoids to biostimulant application varies. The adoption of eco-friendly strategies such as regulated deficit irrigation and biostimulant application can beneficially affect the quality traits of processing tomatoes.
