“…The optimal level of potassium is crucial for improved growth and yield of eggplants and assists eggplant to tolerate salt stress (Rady et al, 2018). The foliar application of potassium improved the potassium uptake in the leaves of plants which increased the fruit set, retention, yield as well and quality (Bons, & Sharma, 2023). This highlights the importance of potassium in eggplant to increase the number of fruits per plant with better quality.…”

Potassium is the keystone nutrient in eggplant cultivation, influencing not only plant health but their ability to absorb essential elements for optimal growth and fruit development. However, the exact relationship between potassium and nutrient uptake by eggplants is still unclear. Three varieties Monarch, Lydia, & Lorraine were used to study the impact of varied potassium levels on the nutrient composition of hydroponically grown eggplant inside the high-tech-greenhouse. The result showed Potassium exerted a pronounced influence on nutrient absorption and leaf composition across various eggplant cultivars. Both low and high levels of potassium resulted in poor K content in the leaves of eggplants. Meanwhile, eggplant grown at optimal levels had higher potassium content in the leaves. The P, Cl, & Na content of leaves decreased with the increase in the application of K in the nutrient medium and was significantly different. The correlation coefficient between K content in leaves was − 0.44***, 0.37***, & 0.44*** with Ca, Cl, & Na respectively. These results emphasize the importance of carefully and precisely balancing potassium fertilization due to its complex interplay of synergistic and antagonistic relationships with essential nutrients, impacting their uptake and distribution.

“…31−33 In our study, exogenous SA, Spd, EBR, and MT treatments also significantly increased the single-fruit weight of blueberry fruits under Cd toxicity compared with CK (p < 0.05) (Figure 1A). Mineral elements, especially the trace elements Fe (the main component of chlorophyll synthesis), Mn, Cu, and Zn, play an important role in plant growth and physiological metabolic activities, and are involved in processes related to photosynthesis, fruit quality, and yield formation; 34 moreover, Cu and Zn as components of most oxidative enzymes directly affect the function of plant oxidative systems, while Mn acts as a catalyst which is closely related to the plant enzyme activity. 35 However, the excessive accumulation of Cd in plants disrupts the uptake and translocation of mineral elements and ultimately inhibits plant growth.…”

Exogenous substances (ESs) can regulate plant growth and respond to environmental stress, but the effects of different ESs on blueberry fruit quality under soil cadmium (Cd) toxicity and related metabolic mechanisms are still unclear. In this study, four ES treatments [salicylic acid (SA), spermidine (Spd), 2,4-epibrassinolide (EBR), and melatonin (MT)] significantly increased blueberry fruit size, single-fruit weight, sweetness, and anthocyanin content under soil Cd toxicity and effectively reduced fruit Cd content to safe consumption levels by promoting mineral uptake (Ca, Mg, Mn, Cu and Zn). Furthermore, a total of 445, 360, 429, and 554 differentially abundant metabolites (DAMs) (LC−MS) and 63, 48, 79, and 73 DAMs (GC−MS) were identified from four comparison groups (SA/CK, Spd/CK, EBR/CK and MT/CK), respectively. The analyses revealed that ESs improved blueberry fruit quality and tolerance to Cd toxicity mainly by regulating the changes in metabolites related to ABC transporters, the TCA cycle, flavonoid biosynthesis, and phenylpropanoid biosynthesis.

“…Supplementation with micronutrients has become an important strategy to improve the nutritional status of plants or to induce a priming effect against abiotic stress conditions in plants. There are few publications considering the responses of Brassica rapa , Pisum sativum , Triticum aestivum , T. durum , and some fruits (Hajiboland & Farhanghi, 2011; Harsimrat & Sharma, 2023; Moitazedi et al, 2023; Tavanti et al, 2021) showing that plants supplied with B demonstrated higher stresses resilience compared to B‐sufficient plants. However, there is still a lack of information on how the foliar supplementation of B as a priming agent can increase the tolerance of agricultural crops to drought stress, especially considering the responses of soybean plant.…”

Drought is the major abiotic stress that limits growth, development and yield of crops worldwide. In this scenario, mineral nutrients, such as boron (B), have been promising for increasing the tolerance of plants to abiotic stresses because of their physiological roles in plants. We aimed to evaluate the benefits of foliar supplementation of B in either relieving or reducing the physiological damages caused by water stress in soybean (Glycine max L.). A greenhouse trial was carried out in a 2 × 3 factorial scheme, with two water conditions (well‐watered and drought stress) and three doses of B (0, 150 and 300 mg B L−1). Foliar application of B was before inducing the water stress, which remained for 20 days during vegetative stage. Plants were evaluated at three moments, according to the water conditions: maximum stress, rehydration and just before harvesting. The levels of hydrogen peroxide and lipid peroxidation increased in soybean leaves and roots under water stress, resulting in impaired plant growth. However, the foliar supplementation with B before the stress increased activities of the antioxidant enzymes and reduced the levels of stress markers. Furthermore, B applied foliar increased the nutrient concentration in the leaves of plants and stimulated root growth, which resulted in higher harvest index related to yield. The foliar application of B has shown as an alternative management to mitigate the damages caused by drought stress in soybean.
