“…Values are means of three replicates for each treatment. LSD -least significant difference a more efficient use of trace elements during the initial growth phase of sorghum plants (de Farias Guedes et al 2020). Our results are consistent with the finding of Bameri et al (2012), who reported the high number of grains per spike, 1 000-grain weight and grain yield of wheat with the foliar application of zinc, iron and manganese.…”

Agronomic bio-fortification is one of the main approaches for mitigation of micronutrient shortage in human populations and endorses sustainable production of food and feed. Studies related to agronomic bio-fortification of crops are mainly focused on single or rarely two micronutrients application, and no attempt has made to study the combined effect of zinc (Zn), iron (Fe) and selenium (Se) on forage sorghum. Therefore, this research was accomplished to evaluate the effect of Zn, Fe and Se bio-fortification on diverse sorghum accessions. The field experiments were conducted in a randomised complete block design with a split-plot arrangement. The treatments comprised of Zn (10 mg/L as ZnSO4∙5H2O), Fe (7 mg/L as FeSO4∙7H2O), Se (3 mg/L as SeSO4) and CK (control) were applied to five sorghum accessions: G1 (Y-16), G2 (YSH-166), G3 (YSH-134), G4 (YSS-98) and G5 (YSH-132). According to our results, the sorghum accession G5 showed superiority over all other accessions and produced maximum values of all growth and quality traits except grains number per panicle and 1 000-grain weight. All applied micronutrients (Zn, Fe and Se) enhanced the growth, quality and uptake of nutrients in sorghum accessions. However, Se recorded the highest plant height, stem diameter, 1 000-grain weight and Zn produced the maximum protein, oil and starch contents. Conclusively, it can be concluded that G5 with Se must be used to achieve the optimum values of agronomic traits, while G5 with Zn found more effective to improve the quality traits of sorghum.

“…In this case, Zn was equally distributed between roots and new leaves (Table 3). Likewise, Farias Guedes et al [36] observed a significant increase in chlorophyll content, with foliar applications of Si to Zn-deficient Sorghum plants. Furthermore, the studies of Pascual et al [28] and Bityutskii et al [13] with soybean and cucumber plants, respectively, did not show significant increases in SPAD or chlorophyll content when Si was added to the nutrient solution (+SiR).…”

Zinc (Zn) is an essential micronutrient involved in a large variety of physiological processes, and its deficiency causes mainly growth and development disturbances, as well as oxidative stress, which results in the overproduction and accumulation of reactive oxygen species (ROS). A possible environmentally friendly solution is the application of silicon (Si), an element that has shown beneficial effects under abiotic and biotic stresses on many crops. Si could be applied through the roots or leaves. The aim of this work is to study the effect of Si applied to the root or shoot in cucumber plants under different Zn statuses (sufficiency, deficiency, and re-fertilization). Cucumber plants were grown in hydroponics, with 1.5 mM Si applied at the nutrient solution or sprayed on the leaves. During the different Zn statuses, SPAD index, fresh weight, ROS, and Si, Zn, P, Cu and B mineral concentration were determined. The results suggested that Si application had no effect during sufficiency and deficiency periods, however, during re-fertilization foliar application of Si, it showed faster improvement in SPAD index, better increment of fresh weight, and a decrease in ROS quantity, probably due to a memory effect promoted by Si previous application during the growing period. In summary, Si application to cucumber plants could be used to prepare plants to cope with a future stress situation, such as Zn deficiency, due to its prompt recovery after overcoming the stress period.

“…Application of silicon causes reduction of plant infestation by diseases [3][4][5][6][7][8][9][10] and pest [5,8,9,[11][12][13]. It also increases the plant's tolerance to drought [14][15][16][17][18][19][20][21][22][23][24][25], high and low temperature [14,[25][26][27], shading [28], flooding with water [14], and deficiency of macro-and micro-nutrients [29][30][31]. Silicon can also reduce the harmful effects of soil salinity, which can be severe problem in some regions [4,[32][33][34][35].…”

Water shortage and drought are a growing problem in Europe. Therefore, effective methods for limiting its effects are necessary. At the same time, the "field to fork" strategy adopted by the European Commission aims to achieve a significant reduction in the use of plant protection products and fertilizers in the European Union. In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was assessed. The fertilizer was used in seven combinations, differing in the number and time of application. The best results were obtained by treating plants during drought stress. The better soil moisture for the plants, the smaller the pure sugar yield increase was observed. It is difficult to clearly state which combination of silicon and potassium foliar application is optimal, as their effects do not differ greatly.
