UTRIENT deficiency on cultivated plants may lead to human malnutrition when consumes these plants. So, the biofortification is a promising approach in increasing several crops in their contents of essentials nutrients for human health like selenium (Se). The current study focused on using two different sources of Se-fertilizers for biofortifying broccoli under nutrient deficiency stress in sandy soil. The applied doses of selenium in each form were 10, 20, 30, and 40 ppm in the form of mineral and biological nano Se-fertilizers. The vegetative parameters and yield of broccoli were determined. In general, the highest growth and yield components were attained for applying the dose of 30 mg Si L -1 for both the soluble and nano Se-forms. The studied parameters included fresh and dry weight of leaves and broccoli head, head diameter and its length gave the highest values when the dose of 30 ppm from both Se-fertilizers applied. The content of N, P, K, and Se nutrients significantly increased by increasing applied Se-doses till 40 ppm in both Se-fertilizers except P. The harvested yield of head broccoli was obtained after applied dose of 30 ppm in case of both Se-fertilizers, with an increase rate for mineral Se-fertilizer 60.1 and 57.2%, whereas were 51.8 and 47.4% for nano-Se fertilizer for both seasons, respectively. The biological Se-nanofertilizer may be is preferable for a safe biofortification. The most distinguished findings in the current study that producing biofortified broccoli rich in Se for human health can be achieved under grown in sandy soils or nutrient deficiency stress. Further studies are needed to answer more open questions regarding producing a safe and healthy food for human nutrition.

“…Foliar or soil application of bio-nanofertilizers can support crop production under abiotic and/or biotic stress by improving the nutritional status and antioxidant system in treated plants. These benefits have been documented with selenium (Se) [ 6 , 7 , 8 , 9 , 10 ], copper (Cu) [ 11 ], and zinc (Zn) [ 12 , 13 , 14 , 15 ]. Under natural conditions and human activities, the distribution of NPs in different agroecosystems is considered an important global issue and still needs more extensive investigations in the hydrosphere, including in groundwater, lakes, rivers, and pore water [ 16 ], the atmosphere [ 17 ], the lithosphere, including mainly soils and sediments [ 18 ], and in the biosphere, including mainly plants, micro-organisms, and even humans [ 19 , 20 ].…”

Strawberry production presents special challenges due the plants’ shallow roots. The rooting stage of strawberry is a crucial period in the production of this important crop. Several amendments have been applied to support the growth and production of strawberry, particularly fertilizers, to overcome rooting problems. Therefore, the current investigation was carried out to evaluate the application of biological nanofertilizers in promoting strawberry rooting. The treatments included applying two different nanofertilizers produced biologically, nano-selenium (i.e., 25, 50, 75, and 100 mg L−1) and nano-copper (i.e., 50 and 100 mg L−1), plus a control (untreated seedlings). The rooting of strawberry seedlings was investigated by measuring the vegetative growth parameters (root weight, seedling weight, seedling length, and number of leaves), plant enzymatic antioxidants (catalase, peroxidase, and polyphenol oxidase activity), and chlorophyll content and its fluorescence and by evaluating the nutritional status (content of nutrients in the fruit and their uptake). The results showed that the applied nanofertilizers improved the growth, photosynthetic pigments, antioxidant content, and nutritional status of the seedlings compared to the control. A high significant increase in nutrient contents reached to more than 14-fold, 6-fold, 5-folf, and 4-fold for Cu, Mn, N, and Se contents, respectively, due to the applied nanofertilizers compared with the control. The result was related to the biological roles of both Se and CuO in activating the many plant enzymes. Comparing the Se with the CuO nanofertilizer, Cu had the strongest effect, which was shown in the higher values in all studied properties. This study showed that nanofertilizers are useful to stimulate strawberry seedling growth and most likely would also be beneficial for other horticultural crops. In general, the applied 100 ppm of biological nano-Se or nano-CuO might achieve the best growth of strawberry seedlings under growth conditions in greenhouses compared to the control. Along with the economic dimension, the ecological dimension of biological nanofertilizers still needs more investigation.

“…Higher enzyme activity may have detoxified free radicals and decreased ROS-induced oxidative injury (Figure 2). El-Badri et al (2022a) observed that exogenously applied Se upregulated the expression of stress-responsive antioxidant genes to mitigate salt stress in B. napus seedlings. Equally, Rossatto et al (2017) reported that reverse transcription quantitative PCR (RT-qPCR) revealed higher expression levels of CAT, APX, and SOD, which detoxified ROS in rice plants to alleviate NaCl toxicity.…”

Various abiotic stresses may affect the germination, growth, and yield of direct-seeded vegetable crops. Seed priming with effective antioxidant mediators may alleviate these environmental stresses by maintaining uniformity in seed germination and improving the subsequent health of developing seedlings. Salt-induced stress has become a limiting factor for the successful cultivation of Brassica rapa L., especially in Southeast Asian countries. The present study was performed to elucidate the efficacy of seed priming using selenium (Se) in mitigating salt-induced oxidative stress in turnip crops by reducing the uptake of Na+. In this study, we administered three different levels of Se (Se-1, 75 μmol L−1; Se-2, 100 μmol L−1; and Se-3, 125 μmol L−1) alone or in combination with NaCl (200 mM). Conspicuously, salinity and Se-2 modulated the expression levels of the antioxidant genes, including catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and ascorbate peroxidase (APX). The upregulated expression of stress-responsive genes alleviated salt stress by scavenging the higher reactive oxygen species (ROS) level. The stress ameliorative potential of Se (Se-2 = 100 μmol L−1) enhanced the final seed germination percentage, photosynthetic content, and seedling biomass production up to 48%, 56%, and 51%, respectively, under stress. The advantageous effects of Se were attributed to the alleviation of salinity stress through the reduction of the levels of malondialdehyde (MDA), proline, and H2O2. Generally, treatment with Se-2 (100 μmo L−1) was more effective in enhancing the growth attributes of B. rapa compared to Se-1 (75 μmo L−1) and Se-3 (125 μmo L−1) under salt-stressed and non-stressed conditions. The findings of the current study advocate the application of the Se seed priming technique as an economical and eco-friendly approach for salt stress mitigation in crops grown under saline conditions.
