Summary: Pea is a widely cultivated leguminous plant that contributes to soil enrichment and crop rotations. Managing weed populations is crucial for pea production, and factors such as soil parameters, environmental influences, and management practices play a significant role in weed composition. Our study identified common weed species and revealed the influence of soil type, farming system, and data collection year on weed infestation.

Summary: Weeds pose serious challenges to maize production, affecting crop yield and farmers' profits. Effective weed management is crucial to minimize the negative impact of weeds on maize. Combining cultural, mechanical, and chemical control methods, such as pre-emergence and post-emergence herbicides, can effectively manage weeds in maize.

Summary: This study found that herbicide efficacy was highest for weed control when applied at high temperatures, especially achieving 100% control values for some herbicides at 35 degrees Celsius. The effectiveness of herbicides on Amaranthus patulus varied depending on the temperature, with higher efficacy at high temperatures for both soil-applied and foliar herbicides.

Summary: Light, temperature, water, and fertilizer play crucial roles in regulating crop growth and productivity. Environmental stimuli, including low light, extreme temperatures, and water stresses caused by climate change, pose a growing threat to sustainable agriculture. Understanding the effects of environmental stimuli on grain filling is essential for crop research and developing strategies to adapt cereals to changing climate conditions and improve grain filling.

Summary: Water availability is a concern for agricultural production, and efficient weed control is needed to mitigate its negative impact on water management. This study aimed to investigate the effect of different doses of glyphosate on water transpiration, water use efficiency (WUE), and intrinsic water use efficiency (iWUE) of the problematic weed Merremia aegyptia. The results showed that the label dose of glyphosate effectively reduced water transpiration and completely stopped it by 12 days after treatment (DAT). Lower doses also reduced water transpiration and increased iWUE compared to the untreated control. Therefore, the application of label dose of glyphosate successfully controlled the weed and reduced its water transpiration.

Summary: Groundwater use can have significant impacts on streamflow and aquatic ecosystems, requiring integrated management strategies. This review evaluates the opportunities and challenges of applying the environmental flows approach to managing streamflow depletion, highlighting the importance of considering temperature and addressing tensions between existing groundwater withdrawal management and environmental flows approaches.

Summary: The study estimated the base temperature and base water potential for four weed species collected from continental Croatia and compared these values with Italian populations. Only the base temperature of Chenopodium album and the base water potential of Amaranthus retroflexus were found to be similar between the two populations. Further field experiments are needed to validate these results.

Summary: Weed control is a significant issue in sugarcane production in Thailand, with post-emergence herbicide application being the most popular method. However, improper use of herbicides can result in toxicity and lower yield components. Experiments with paraquat and ametryn showed that applying the correct rates at the tillering stage is essential for controlling different weed species.

Summary: Current advancements in environmental RNA (eRNA) focus on using its fast turnover rate to assess metabolically active community diversity. However, this approach underutilizes the potential ecological information encrypted in eRNA. The authors argue for using eRNA to detect organisms with unique eRNA profiles beyond current species-level capabilities, and discuss its future applications in assessing physiological status and ecological health.

Summary: The study demonstrates the potential use of electrophysical treatment as an effective weed control tool, especially with greater damage caused by direct leaf contact treatments. Early growth stages of plants are more sensitive to treatments, and temperature increase appears to be a key control factor.

Summary: Predicting weed emergence in crop production systems is a global challenge that requires understanding mechanisms of weed ecology and trait evolution in response to climate change and altered agricultural practices. Seed dormancy, which controls germination by defining environmental conditions, plays a key role in weed soil seed bank persistence and seedling emergence timing. Integrating seed dormancy dynamics in variable field environments across generations is essential for more sustainable weed management strategies.

Summary: Environmental water markets have been successful in the absence of certain legal conditions, with substantial market activity driven by government regulatory and conservation programs. The majority of funding comes from government sources, and current market activity is insufficient to prevent water restrictions for critical users in the Colorado River basin, indicating a need for additional investment.
