“…Se promotes greater assimilation and allocation of C to the roots, altering the morphology of the root system (Hamed-Far et al, 2022). Therefore, by making Se available to onion plants, there will be greater water absorption by the roots, resulting in greater dry mass accumulation (Mobini et al, 2019).…”

The common climatic characteristics in semi-arid regions can cause abiotic stress and be a limiting factor for crops. Under these conditions, the use of beneficial elements such as selenium (Se) is an alternative to mitigate the harmful effects of abiotic stresses and increase yield. Therefore, this research aimed to evaluate the agronomic performance of onion grown in a semi-arid region under the application of Se. A field experiment was performed in a randomized block design, where five doses of Se (0, 15, 30, 45, and 60 g ha-1), by foliar application, were tested on two onion hybrids (Andrômeda and Rio das Antas). Growth, nutritional and yield variables were analyzed. Se increased the height and accumulation of dry mass in onion plants, with a maximum at the 60 g ha-1 dose of Se, the same dose at which the highest commercial (78.15 t ha-1) and total (86.03 t ha-1) bulb yields were obtained in Rio das Antas; however, for Andrômeda, there was no effect of Se on yield. Applied Se doses also increased the content of this element in the bulbs. Despite increasing bulb yields only in the Rio das Antas hybrid, 60 g ha-1 of Se is recommended for onions due to its effects on plant growth and the biofortification of bulbs with Se.

“…However, different results were obtained in agricultural research. In the study by Mobini et al [ 36 ] where onion was grown with the application of Se and S to the nutrient solution, it was determined that the addition of Se had no significant effect on the content of S in the bulbs, while the addition of S (1–3 mM) led to a decrease in Se content in the bulbs. On the other hand, a study by Kopsell and Randle [ 37 ] indicated that with the increase of Se concentration, the content of S in the bulbs of different onion cultivars decreased.…”

Allium species are known as a rich source of many compounds with potential healing effects. Biofortification is recognized as an effective agrotechnical measure for raising the level of biogenic elements—especially microelements in the edible parts of these species, so Allium can be considered as a ‘natural dietary supplement’. The aim of this research was to test the effects of foliar application of Se fertilizer (Na2SeO4) in different doses (control—0, 10, 20 and 30 g per ha) on the content of macro, microelements and secondary metabolites (SMs)—free phenolics, flavonoids and hydroxycinnamic acid derivatives in the edible parts, i.e., leaves of two selected Allium species in Serbia (A. odorum and A. schoenoprasum), which grew in open field conditions over the course of two growing seasons. The bioaccumulation factor (BAF), as an indicator of the ability of plants to accumulate biogenic elements, was also determined. Although with no full regularity, the dose of 10 g of Se per ha yielded the highest content for the most biogenic elements for both alliums in the first growing season, i.e., a dose of 20 g of Se per ha for A. schoenoprasum, and a dose of 30 g of Se per ha for A. odorum in the second growing season. The obtained results justified the Se-biofortification of different alliums. The BAF values indicated the ability of both Allium species to accumulate S, K and P in their leaves during both growing seasons. The accumulation of potentially toxic elements was not recorded for either species, emphasizing the safety of the produced plant material for human consumption. Additionally, Se-treated plants had higher SM contents compared to control plants. The growing season also showed an impact on SM content; i.e., in the second season, characterized as drought-stressed, the synthesis of SMs was significantly higher compared to that in the first season. Further research should be directed towards finding the appropriate dose of Se, expanded in the sense of conducting research in controlled conditions, as well as different ways of applying Se fertilizer. The idea of this study was also to popularize the examined Allium species, which are rarely grown in the territory of Serbia.

“…The co-application of selenium with an N carrier improved the efficacy of Se fertilizers without additional application costs in the field [137]. Sulfur was reported to increase selenium uptake from organic-rich soils [69] and bulb yield in onion [138]; contrariwise, selenate was shown to promote the accumulation of S and P in buckwheat [130]. Another element influencing selenium intake is iodine; foliar application of iodine on Indian mustard caused a decrease in selenium uptake by 4% [124].…”

“…According to Smole ń et al [133], the consumption of 100 g of carrots fortified with 1 kg•ha −1 selenium and 5 kg•ha −1 iodine can supply 100% of the recommended daily intake for both nutrients. In another study, the authors stated that the consumption of biofortified onions treated with 25 µM selenium would exceed the recommended daily intake of selenium in countries where the daily average consumption of onions exceeds 24 g [138].…”

Current Strategies for Selenium and Iodine Biofortification in Crop Plants

Selenium and iodine are essential trace elements for both humans and animals. Among other things, they have an essential role in thyroid function and the production of important hormones by the thyroid gland. Unfortunately, in many areas, soils are deficient in selenium and iodine, and their amount is insufficient to produce crops with adequate contents to cover the recommended daily intake; thus, deficiencies have an endemic character. With the introduction of iodized table salt in the food industry, the thyroid status of the population has improved, but several areas remain iodine deficient. Furthermore, due to the strong relationship between iodine and selenium in metabolic processes, selenium deficiency often compromises the desired positive impact of salt iodization efforts. Therefore, a considerable number of studies have looked for alternative methods for the simultaneous supplementation of selenium and iodine in foodstuff. In most cases, the subject of these studies is crops; recently, meat has also been a subject of interest. This paper reviews the most recent strategies in agriculture to fortify selenium and iodine in crop plants, their effect on the quality of the plant species used, and the potential impact of food processing on their stability in fortified crops.
