“…The positive effects of N fertilization can probably be explained by the fact that N is a constituent of the chlorophyll molecule, and applying N combined with K significantly increased the chlorophyll content (Table 2), which is essential for photosynthesis [11]. Under N 3 (914.70 mg L −1 ), the stem diameter, leaf number, and chlorophyll content decreased with the K application, thereby indicating the unfavorable effect of excessive N application on the development of L. lancifolium, where top growth was inhibited [31,32]. El-Magd et al [33] reported that the K application improved the plant length, leaf number, and bulb dimensions in sweet fennel.…”

Lilium lancifolium is a plant resource used as both medicine and food because it is enriched with polysaccharides, polyphenol compounds, and saponins. Increasing the quality of Lilium species is based largely on improvement using methods such as selective breeding and proper fertilization. In this study, we investigated the different responses of L. lancifolium bulbs to treatment with nitrogen (N) and potassium (K) in Hoagland solution. A pot experiment was conducted with four N rates and five K rates under a completely random design. The agronomic traits, N and K contents, and concentrations of active compounds were determined in bulbs, including total phenols, flavonoids, polysaccharides, and saponins. L. lancifolium treated with N and K exhibited increases in the plant height, leaf number, and chlorophyll content compared with the control (N0 + K0). The bulb circumference increased by 17.41% under N2 (609.80 mg L−1) + K2 (523.34 mg L−1) compared with N0 + K0. Individual or combined application of N and K increased the total phenol, flavonoid, and saponin contents, especially under N2 + K3, with the highest increases of 1.87–2.93 times compared with N0 + K0. However, the individual application of N decreased the polysaccharide contents by 2.78–42.04%. Hoagland solution containing 443.24–572.87 mg L−1 N and 573.61–759.16 mg L−1 K is recommended to improve the active contents of bulb components based on regression analysis. Our results demonstrate that the combined application of N and K is important for obtaining high-quality L. lancifolium bulbs.

“…As reported by Naumann et al [73], the photosynthetic process, including diffusion of CO 2 to the chloroplasts and stomatal opening, can be inhibited by salinity (K + , Na + ) [74,75]. In addition, the process by which K enters a plant is considered to be very complex, as it is a mixture of uptake and utilization [76]. K uptake is mainly controlled by root characteristics (e.g., root architecture, root exudates, and root surfaces), while the utilization of K can be estimated from the responses of crop yield and quality [71,77,78].…”

Sugar beet is one of the main sugar crops and an important cash crop in the three northern regions of China (Northeast China, North China, and Northwest China). As an arid region, Xinjiang lacks water resources. The establishment of a reasonable drip-irrigation system for sugar beet in Xinjiang can not only achieve the goal of high quality and high yield, but is also crucial for the efficient utilization of water and fertilizer. This research was implemented in the experimental field of the Xinjiang Academy of Agricultural Sciences’ Sugar Beet Improvement Center in Manas County, Xinjiang, from the year 2019. Taking ST 15140 sugar beet as the experimental variety, a field study was conducted to investigate the effects of different irrigation and fertilization methods on the yield and sugar content of sugar beets. Ten treatments of two irrigation levels (W1: 4500 m3 ha−1, W2: 5400 m3 ha−1) and five fertilization methods (F1, F2, F3, F4, and F5) were carried out in a randomized block design with three replications. The yield and sugar content; growth indicators such as leaf photosynthetic rate, stomatal conductance, chlorophyll content and intercellular CO2 concentration; and fertilizer-use efficiency (nitrogen-use efficiency (NUE), phosphorus-use efficiency (PUE), and potassium-use efficiency (KUE)) during the sugar beet growing seasons were determined. The results indicated that the W1F3 (4500 m3 ha−1, N 229.5 kg ha−1 + P2O5 180 kg ha−1 + K2O 202.5 kg ha−1 + hydroquinone 229.5 g ha−1) treatment had the highest yield and sugar content of 132.20 Mg ha−1 and 15.61%, respectively. For crop growth indicators, the photosynthetic rate (33.27 μmol m−2 s−1) and the stomatal conductance (252.67 mmol m−2 s−1) under W1F3 were both the highest among all of the treatments. The fertilizer-use efficiency in W1F3 was in the following order: KUE > NUE > PUE. The highest KUE (128.10%) and NUE (65.49%) occurred under W1F3 at the sugar accumulation stage of the crop growing season. In addition, K determined the yield and sugar content of sugar beet by influencing growth factors such as the photosynthetic rate, chlorophyll content, intercellular CO2 concentration, along with the KUE, which explained 30.2%, 5.1%, 10%, and 14.7% of the variation in yield and sugar content, respectively. The results of this study indicated that the application of an inhibitor with optimized-minus-N fertilization under lower irrigation (W1F3) was the optimal treatment. Above all, K determined the yield and sugar contents of sugar beets, emphasizing the pivotal role of K in the growth, physiological processes, and output of sugar beets.
