Can Nanofertilizers Mitigate Multiple Environmental Stresses for Higher Crop Productivity?

Sustainability, Год журнала: 2022, Номер 14(6), С. 3480 - 3480

Опубликована: Март 16, 2022

The global food production for the worldwide population mainly depends on huge contributions of agricultural sector. cultivated crops foods need various elements or nutrients to complete their growth, and these are indirectly consumed by humans. During this production, several environmental constraints stresses may cause losses in production. These obstacles include abiotic biotic stresses, which have already been studied both individual combined cases. However, there very few studies multiple stresses. On basis myriad benefits nanotechnology agriculture, nanofertilizers (or nanonutrients) become promising tools sustainability. Nanofertilizers also proper solution overcoming health problems that can result from conventional fertilizers. role has increased, especially under different individual, combined, most commonly nature; however, still needed stress levels. play a crucial supporting plants improving plant yield, quantitatively qualitatively. Similar other biological issues, many open-ended questions require further investigation: Is right time era agriculture? Will be dominant source modern Are nanofertilizers, particularly synthesized ones, magic sustainable What expected damages plants?

Using nanofertilizers in certain concentrations can be a novel method to alleviate drought stress effects plants as global climate problem. We aimed determine the impacts of zinc nanoparticles (ZnO-N) and sulfate (ZnSO4) fertilizers on improvement tolerance Dracocephalum kotschyi medicinal-ornamental plant. Plants were treated with three doses ZnO-N ZnSO4 (0, 10, 20 mg/l) under two levels [50% 100% field capacity (FC)]. Relative water content (RWC), electrolyte conductivity (EC), chlorophyll, sugar, proline, protein, superoxide dismutase (SOD), polyphenol oxidase (PPO) and, guaiacol peroxidase (GPO) measured. Moreover, concentration some elements interacting Zn was reported using SEM-EDX method. Results indicated that foliar fertilization D. decreased EC, while application less effective. sugar proline well activity SOD GPO (and extent PPO) by 50% FC, increased influence ZnO-N. could increase chlorophyll protein PPO this plant stress. Based results, then improved through their positive physiological biochemical attributes changing Zn, P, Cu, Fe. Accordingly, due also antioxidant enzyme (SOD, GPO, enhancing plant, is advisable.

Chitosan and Zinc Oxide Nanoparticle-Enhanced Tripolyphosphate Modulate Phosphorus Leaching in Soil

ACS Agricultural Science & Technology, Год журнала: 2023, Номер 3(6), С. 487 - 498

Опубликована: Май 31, 2023

Phosphorus (P) loss from agro-ecosystems impinges upon P use efficiency by plants and thereby constitutes both agronomic environmental nuisances. Herein, we report on the potential for controlling leaching application in crop fertilization through repurposing nano-functionalizing tripolyphosphate (TPP) as a sole source. The developed TPP-Chitosan TPP-Chitosan-ZnO nanofertilizers exhibited positive surface charges, 5.8 13.8 mV, hydrodynamic sizes of 430 301 nm, respectively. In soil, nanoformulations significantly reduced cumulative during 72 h, reaching 91 97% reductions, respectively, compared to conventional fertilizer, monoammonium phosphate (MAP). Cumulative after h these was, 84 95% lower than TPP alone. overall, 65% more effective reducing leaching, TPP-Chitosan. Relative MAP, wheat plant height was increased 33.0%. Compared slightly grain yield 21 30%, Notably, decreased shoot levels, 35.5, 47, 45%, TPP, TPP-Chitosan, Zn release over considerably lower, control, ZnO nanoparticles, averaged, 34.7 0.065 mg/L, which 534 times higher former. Grain treatment, relative MAP. also mobilized resident K, S, Mg, Ca soil into plant, helping improve overall nutritional quality supporting role chitosan nutrient mobilization. Taken together, our data highlight non-fertilizer material, agricultural applications effect applying nanotechnology such outcomes. Broadly speaking, reduction is critical eutrophication water bodies due overload sustaining dwindling global resources.

Bespoke ZnO NPs Synthesis Platform to Optimize Their Performance for Improving the Grain Yield, Zinc Biofortification, and Cd Mitigation in Wheat

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(2), С. 716 - 727

Опубликована: Янв. 4, 2024

Nanomaterials (NMs), particularly ZnO nanoparticles (NPs), show great promise in sustainable agriculture for enhancing crop production, mineral nutrition, and food safety. However, custom synthesis of NMs to optimize performance is still a bottleneck. This study synthesized three types (NPs) (nZnO-1, nZnO-2, nZnO-3) with different particle size, charge, dissolution properties were foliar-applied wheat under field conditions. Foliar application nZnO-3 significantly increased grain by 15.2% biological yield 9.5% compared that the unamended control. Both nZnO-2 improved Zn content whole (21.0 15.6%, respectively) starchy endosperm (31.8 13.1%, respectively), enhanced bioavailability (40.9 43.3%, estimated daily intake (EDI) (55.1 23.8%, respectively). Impressively, also reduced Cd concentration (17.2%) although it did not affect level flour. Additionally, all treatments levels crude protein (5.2–15.7%) other nutrients (e.g., S, Fe, Mn) grains. These findings underscore potential tailored NPs biofortification point toward approach agricultural production through controlled platform.
