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: In this study, it was found that soil waterlogging significantly affected the growth and productivity of cotton. The application of potassium fertilizer improved the water status, photosynthetic capacity, and growth of cotton under waterlogged conditions. Additionally, it reduced flower abscission and increased the number of bolls and fruit nodes.

Summary: This study evaluates the effects of different cover crops, potassium application timing, nitrogen application rate, and growing season on cotton yield, yield components, and yield quality. The study finds that early potassium application can increase cotton yield under lower nitrogen application rate in low-fertility sandy soil. The choice of cover crops and growing season also affect cotton yield and quality.

Summary: High planting density can increase total boll number per unit ground area, thus boosting cotton yield, while maintaining stable single boll weight. The main-stem leaf plays a crucial role in sustaining photosynthesis of the boll-leaf system, and photosynthetic performance in sympodial leaves can be adjusted to enhance overall photosynthesis of the system.

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: One of the main goals for breeders is to develop high-yield cultivars. Recent efforts have focused on improving photosynthetic efficiency in order to enhance yield. Leaf shape, especially the sub-okra leaf, has been shown to have significant effects on plant architecture, biomass accumulation, and yield in upland cotton. The sub-okra leaf improves plant canopy structure, optimizes the light environment, and increases total biomass and yield, making it a potential practical application for sustainable and profitable cotton production.

Summary: Soil available phosphorus deficiency can reduce boll biomass and lint yield in cotton, affecting the ratios of boll wall to boll, lint to boll, and lint to seed. Low soil phosphorus has a greater impact on fiber and starch content, as well as the activity of sucrose-metabolizing enzymes. Different cotton cultivars vary in their sensitivity to low soil phosphorus.

Summary: Long-term continuous cotton cropping leads to a decrease in soil quality and organic carbon, which negatively impacts cotton yield. The application of organic amendments, such as cotton straw and organic manure, can improve soil fertility and increase cotton yield. This study found that the combination of cotton straw and organic manure significantly improved soil quality, stability, and sustainability of cotton yield.

Summary: Organic fertilizers are important for improving farmland fertility. A study in the semi-arid area of the Loess Plateau in northwest China examined the effects of different nutrient sources and application rates on water consumption characteristics, grain yield, and water use efficiency of oilseed flax. The results showed that organic fertilizers significantly increased soil water storage capacity and reduced water consumption. Specifically, the application of 25,000 kg/hm² sheep manure improved soil water storage, reduced water consumption, and increased grain yield and water use efficiency.
