... Se plays a key role in the antioxidant systems in plants, studies have shown that application of Se at low doses protect the plants from variety of abiotic stresses such as temperature (Chu et al., 2010;Djanaguiraman et al., 2010Djanaguiraman et al., , 2018, drought (Hasanuzzaman et al., 2011), desiccation (Pukacka et al., 2011), aging (Djanaguiraman et al., 2005Hartikainen, 2005), and metal stress (Kumar et al., 2012;Pandey & Gupta, 2015;Ghorai et al., 2022). Se, applied at low concentrations, enhances growth and antioxidative capacity of both International Journal of Food Science and Technology 2022 mono and dicotyledonous plants (Kavalcová et al., 2015;Shalaby et al., 2017;El-Sayed et al., 2020;Cipriano et al., 2022). However, at high Se doses, it acts as pro-oxidant and causes oxidative stress in plants (Mroczek-Zdyrska & Wójcik, 2012;Mora et al., 2015;Mroczek-Zdyrska et al., 2017). ...
... Lead was distinguished by the highest values of the content in the soil, and cadmium was the lowest (Table 2). However, Zn and Cu had the highest concentration in phytomass which is probably related to their obligatory functions in the plant [18]. According to plant-up-taking indexes studied elements can be ranked in the following descending order: Cu > Zn > Cr > Cd > Pb. ...
... As a micronutrient, Ni is important for the formation of several metallo-enzymes in higher order plants, including urease, Ni-Fe hydrogenase and Ni-superoxide dismutase [27,28]. Urease can hydrolyse urea to ammonia, preventing toxic build-up and assisting the formation of N-based molecules such as amino acids in plants [29]. ...
... Sulfur is an essential macronutrient; according to its chemical nature it plays important roles in various cellular metabolic processes [1]. As an organic thiol it is incorporated in essential amino acids such as cysteine, methionine and different co-enzymes (biotin, coenzyme A, iron-sulfur proteins, ethylene, thiamine pyrophosphate and lipoic acid), and thioredoxins and sulfolipids are often responsible for the structure and biological activity of proteins [2,3]. Recently, it has been noted that a deficiency of sulfur in soil is a problematic issue which leads to reduction in yield and quality of seeds. ...
... Molybdenum Bonilla et al. (1980) studied the effect of boron deficiency and toxicity on the N metabolism of sugar beet and found Mo and N-Rase activity in leaf decreased, while NO3-N in the sap, K and B in the leaf increased with increasing B supply. The authors suggested that the low level of Mo and increase in NO3-N and K were probably related to reduced N-Rase activity and K-NO3 synergism (Abou seeda et al., 2020). In general, B functions in relation to other plant nutrients has led to the conclusion of some investigators (Tanada, 1983 andMozafar, 1989) that B plays a role in the integrity and function of plant membranes. ...
... Industrial operations are the primary cause of toxic emissions of heavy metals to the environment Nie et al., 2020). These pollutants may get bioaccumulated and/or magnified at higher trophic levels via food chain, resulting in serious health threats (Zaghloul et al., 2020;Kumar et al., 2020a). These days, waste management is one of the main environmental concerns (Kumar et al., 2020b,c). ...
... With increasing salt concentration in the root zone, plant growth was negatively affected due to increasing osmotic pressure and /or ion toxicity. Also, salinity affects photosynthesis by decreeing CO 2 availability (Prakash et al., 2010;Abou El-Nour et al., 2017;Yassen et al., 2018). However, spraying micronutrients (single nutrient or mixed) increased plant growth. ...
... The different modes of SiNPs application such as seed priming (Janmohammadi and Sabaghnia, 2015), root application (Attia and Elhawat, 2021), or foliar application (Mukarram et al., 2021a) seem to impart beneficial crops in different plants irrespective of the mode of supplementation, although the intensity of these effects varies. Exogenous supplementations of SiNPs induced vegetative growth and development in many crops such as cucumber (Yassen et al., 2017;Alsaeedi et al., 2019a), mint (Mentha piperita L.) and tuberose (Karimian et al., 2021). SiNPs promoted plant growth in oat via enhanced expression of phenylalanine ammonia-lyase (PAL) and lignification in leaves and roots without any toxicity (Asgari et al., 2018). ...
... This is in line with the findings of Attia and Khater (2015) and Gendy et al. (2012) on roselle, declaring that CMn increased all vegetative growth traits, sepals, and seed yields. Besides, several reports carried out on several plants indicated that applying CMn markedly increased growth characteristics [Tara et al. (1996) on Mentha piperita; Khalil (2002) on Rosmarinus officinalis and Tagetes erecta; Badran and Safwat (2004) and El-Ghawwas et al. (2002) on Foeniculum vulgare; Shalan (2005) on Nigella sativa; Khalid et al. (2006) on Calendula officinalis]. ...
... Several other studies have indicated beneficial effects on maize crop resulting from combined application of nitrogen fertilizers with bio-fertilizers (Abido et al. 2017;Gao et al. 2020). Similarly, integrated application of nitrogen with other minerals such as Selenium in potato (Yassen et al. 2011) and potassium in elephant grass (Stida et al. 2018) has positively impacted crop growth and yield. ...
