Summary: Cotton production efficiency in arid climates is constrained by low nitrogen utilization rate and high nitrogen application rate. Allocating more nitrogen to late application can alleviate these issues and improve plant growth and yield. A three-year field experiment showed that late nitrogen application narrowed plant width, increased canopy light transmittance, extended boll growth period, improved defoliation, and increased seed cotton yield. Therefore, adopting a late nitrogen application strategy can be an efficient fertilizer management approach in arid areas.

Summary: Waterlogging is a crucial environmental factor that limits maize production during the early growing stage. This study investigated the effects of varying nitrogen fertilizer application rates on shoot biomass accumulation and its distribution, nitrogen uptake, and nitrogen use efficiency in maize under waterlogged conditions. The results showed that waterlogging significantly reduced shoot biomass and nitrogen accumulation, but increasing nitrogen application rates improved these parameters. Higher nitrogen treatments also increased root biomass and length density, resulting in enhanced nitrate reductase activity and nitrogen use efficiency. Moreover, the highest nitrogen treatment improved biomass distribution in the kernel and facilitated biomass transfer to the grain, leading to an enhanced harvest index. Therefore, increasing nitrogen application rates can improve biomass accumulation and utilization in waterlogged maize.

Summary: This study compared the waterlogging tolerance of commercial cotton varieties from three major cotton-growing regions in China and found that cotton varieties from the Yangtze River valley and Yellow River valley exhibited greater tolerance to waterlogging than those from the Northwest Inland. The study also revealed that cotton adapts to waterlogging stress through quiescence adaptation and compensatory growth, providing insights for breeding waterlogging-tolerant cotton varieties and improving cultivation practices.

Summary: Nitrogen availability and form significantly impact N uptake and assimilation in plants, with barley showing better growth under inorganic nitrogen (NO3-). Wild barley, particularly XZ179, appears to have a higher tolerance to organic nitrogen (glycine) compared to cultivated barley. Ammonium adversely affects growth parameters in both wild and cultivated barley genotypes.

Summary: Long-term cotton stubble return and subsoiling can improve soil microbial community and carbon and nitrogen dynamics in coastal saline soil, leading to enhanced sustainability. The bacterial community is primarily influenced by soil compartments, while the fungal community is mainly affected by stubble management. Stubble return increases the abundance of beneficial bacteria and fungi, resulting in higher microbial biomass carbon and nitrogen sequestration. Plant growth promoting rhizobacteria have a greater influence on the rhizosphere microbial community and carbon and nitrogen dynamics than pathogenic fungi.

Summary: In this study, the effects of nitrogen application rate and allocation ratio on cotton yield and nutrient use efficiency were assessed using Lumian 532, a high-yielding cotton variety in the North China Plain. The results showed that the optimal nitrogen application rate for Lumian 532 was 220 kg hm(-2), with an allocation ratio of 3:5:2. These findings provide practical insights into nutrient demand, cotton yield, and ecological protection in different growth stages of cotton in the North China Plain.

Summary: The study found that under dry conditions, root capacitance (ECroot) was significantly reduced after root cutting, and that incorporating root tissue density and soil moisture into the prediction model can improve the accuracy of ECroot. In contrast, ECroot was less affected by root cutting under wet soil conditions, suggesting that it may not directly measure roots in these conditions.

Summary: Nitrate application significantly promotes cadmium accumulation in sweet sorghum compared to ammonium, leading to higher dry weight and Cd concentrations. The effects of nitrate on Cd accumulation and antioxidant capacity under Cd stress are stronger than those of ammonium, indicating that nitrate is more suitable for Cd phytoextraction in sweet sorghum.

Summary: This study investigated the impact of low nitrogen on root senescence in cotton. Results showed that nitrogen starvation induced premature leaf senescence but delayed root senescence due to increased catalase activity and decreased malonaldehyde content with low nitrogen treatment. Changes in gene expression also indicated upregulation of glutathione and ascorbate peroxidase synthesis genes and downregulation of ABA, apoptosis, caspase, and cell cycle-related genes. Overall, this study provides new insights into the effects of nitrogen starvation on root senescence.

Summary: This study found that silicon (Si) can enhance the photosynthesis rate and growth of cotton under salt stress, while reducing reactive oxygen species (ROS) accumulation. Si addition also enhanced antioxidant enzyme activity and protected chloroplast structure in salt-stressed cotton. Additionally, Si increased stomatal density and aperture in salt-stressed cotton seedlings.

Summary: This study found that low P availability negatively affects the growth and photosynthesis of cotton, leading to a decrease in leaf area, dry weight, and gas exchange parameters. Furthermore, low P availability also reduces the activity of antioxidant enzymes and increases the content of malondialdehyde in cotton. These findings provide a theoretical basis for understanding the growth and tolerance of cotton under low-P conditions.
