“…Therefore, Fe-enriching fertilizers are required to ensure optimum Fe delivery to the plants. Recently, there has been a thrust to develop innovative fertilizer formulations like nanoparticle (NP) fertilizers because conventional fertilizers are required in large quantities owing to their slower absorption by the plants [4][5][6]. The NP fertilizers can facilitate tunable delivery of the required nutrients to the plants.…”

There is an emerging scientific interest in the use of nanoparticle fertilizers for enhanced agricultural and bioenergy crop production to meet the growing food and energy demands of the world. The objective of designing the nanoparticle fertilizers is to effectively deliver the required nutrients for the plants without adding large quantities of fertilizer to the environment. However, most reports on nanoparticle fertilizers so far, involved the addition of nanoparticles to the hydroponic system or the soil. In this study, we report a new modified seed presoak strategy using a drop of Fe-enriching hematite nanoparticle dispersion to enhance plant growth and production in four different legume species, i.e., chickpea, green gram, black bean, and red bean. The hematite nanoparticle fertilizer drop promoted a 230-830% increase in plant growth with green gram showing the highest increase, based on our prolonged and statistically reliable growth studies. In general, we observed an increase in the survival span of plants, a twofold increase in fruit production per plant, nearly two times faster fruit production, and healthy secondgeneration plants with the nanoparticle treatment; however, there were slight species-specific variations. We used a novel multimodal material characterization approach combining three techniques, hyperspectral imaging, Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma optical emission spectroscopy (ICP-OES), to evaluate the internalization and transport of the nanoparticle fertilizer within the plants. Our results indicated that the hematite nanoparticles were transported through the roots and stems and were localized in the leaves after 10 days of growth in pots of soil. Therefore, the modified seed presoaking method using a drop of hematite nanoparticle will be highly attractive in enhancing plant growth and health, while minimizing environmental impacts.

“…Palavras Chave: nanotecnologia; Solanaceae; inseto; transferência trófica; espectroscopia por fluorescência de raios-X In the last 20 years, there has been great development and use of nanotechnology in the electronics, automotive, energy, medicine, and agricultural sectors (Paschoalino et al 2010;Vance et al 2015). Several academic studies suggest that nanoCuO, nanoZnO, nanoCeO 2 , and nano TiO 2 can be used in fertilization by seed treatment (Duran et al 2017), or broadcast on foliage and soil (Raliya et al 2018). Additionally, they also may be applied as pesticides (Khot et al 2012).…”

All technological innovation that influences research to achieve yields and counteract biotic and abiotic stress in crops should be a priority for governments and scientists around the world. Silicon nanoparticles (NpSi) in the production and protection of crops are used as a sustainable strategy. In addition to NpSi, other nanoparticles have been applicable in areas such as environmental remediation, medicine and smart sensors. There are plants that accumulate high concentrations of Si in their tissues, such as "horsetail" (Equisetum arvense). A recent analysis of the elemental composition of E. arvense in a cross section, epidermis, and total biomass indicated that the Si concentration was higher in comparison with macro and micronutrients. Elemental mapping showed that all polymerized silicon (SiO2 • nH2O) is available in the epidermis of Equisetum. Currently, our team is investigating the extraction, purification and quantification of SiNp. The lines of emerging research should be those related to the interaction of SiNp in the cell wall, concentration and intelligent application with aerial equipment in crops such as vegetables, cereals, and fruits.
