Summary: The optimal plant density and nitrogen application rate are crucial for achieving high maize yield. High plant density intensifies plant-plant competition for light and nutrients, while excessive nitrogen application leads to excessive vegetative growth and delayed maturity, reducing nitrogen use efficiency. The physiological and molecular mechanisms of the interaction between plant density and nitrogen application rate are currently unknown.

Summary: This study aimed to investigate the impact of different levels of biochar (BC) and nitrogen (N) application on the performance of maize-soybean intercropping system. The results showed that the treatment of 15 t ha(-1) BC and 180 kg ha(-1) N increased grain yield and water use efficiency (WUE), while 15 t ha(-1) BC and 135 kg ha(-1) N enhanced nitrogen recovery efficiency (NRE) in both years. However, nitrogen promoted the protein and oil content of intercropped maize, but decreased the protein and oil content of intercropped soybean. Moreover, BC did not improve the protein and oil content of intercropped maize, but increased maize starch content. BC had no positive impact on soybean protein, but it unexpectedly increased soybean oil content. The comprehensive assessment value first increased and then declined with increasing BC and N application. These findings provide a comprehensive understanding of the growth of maize-soybean intercropping system and its potential to enhance production in northeast China.

Summary: Balanced nitrogen-iron (N-Fe) sufficiency has been found to significantly increase tiller number, yield, and nitrogen use efficiency (NUE) in rice and wheat. NIN-like protein 4 (OsNLP4) plays a crucial role in maintaining the N-Fe balance by regulating the expression of multiple genes involved in N and Fe metabolism and signaling. Balanced N-Fe sufficiency promotes the nuclear localization of OsNLP4 by reducing H2O2 levels, reinforcing its functions in promoting tillering.

Summary: Genetic improvement has led to higher grain yield and nitrogen use efficiency (NUE) in current wheat cultivars in the Yangtze River Basin. This study examined 21 local cultivars and found positive correlations between grain yield and NUE. The high-yield cultivars had more effective ears, higher tiller fertility, greater single-spike yield, longer leaf stay-green ability, and greater photosynthetic rate.

Summary: The study focused on the effects of nitrogen fertilization rate and time of application on winter wheat yield and biomass production efficiency. It found that nitrogen rate significantly influenced grain yield and biomass production efficiency, with 120 kg/ha as a critical point. The timing of nitrogen application also had a highly significant impact on grain yield, biomass, and nitrogen use efficiency.

Summary: This study conducted a field experiment to evaluate cotton yield, fiber quality, growth, and maturity responses to different nitrogen application rates in the southeastern US. It found that both excessively high and low nitrogen levels can significantly affect cotton productivity, fiber quality, and growth, with photosynthetic rates being responsive to nitrogen rates on later sample dates.

Summary: Nitrogen plays a crucial role in cotton growth and yield. This study found that moderate to high levels of nitrogen improved the growth, photosynthesis, and yield of CCRI-69 cotton. These levels also increased the enzymatic activities involved in carbon and nitrogen metabolism in the subtending leaves. There was a strong correlation between the nitrogen concentration in subtending leaves and various physiological parameters and yield. These findings highlight the importance of nitrogen concentration in subtending leaves for improving cotton yield and could be used in breeding nitrogen-efficient cotton genotypes.

Summary: The study demonstrates that improved N partitioning efficiency in newer cultivars and high levels of residual soil nitrate-N allow sustained plant growth and yield, even with reduced N application. Reducing N inputs in residual N-rich soils is advantageous for maintaining yield and increasing profits.

Summary: The article addresses the lack of harmonization of NUE terminology and definitions in Australia, reviews and collates metrics used to measure NUE both domestically and internationally, and proposes a suite of key NUE indicators. Worked examples based on data from the Australian Government's MPfN Program are used to compare NUE values between industries and identify opportunities for improvement through management strategies. A framework for NUE indicators was adapted for Australian irrigated cotton and sugarcane cropping systems based on a generic framework developed by the EU Nitrogen Expert Panel.

Summary: This study investigated how cotton plants balance nitrogen (N) metabolism and enhanced biomass accumulation to support larger root systems under low N stress. The results showed that high N-efficient genotype CCRI-69 produced a larger root system, high biomass accumulation, and efficient N metabolism compared to N-inefficient genotype XLZ-30. The key traits contributing to N use efficiency (NUE) were root morphology, sugar contents, and N-assimilating enzymatic activities.

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.
