Synthesis of Mesoporous Silica and Graphene-Based FeO and ZnO Nanocomposites for Nutritional Biofortification and Sustained the Productivity of Rice (Oryza sativa L.)

Considering nutrient delivery and micronutrient use efficiency problems, mesoporous nanosilica (mNs) reduced graphene oxide (rGO)-based iron zinc nanocomposites were formulated. Prepared characterized for FTIR spectroscopy, XRD, FE-SEM, HR-TEM, AAS to examine surface functional groups, morphology, structural composition. XRD spectrum confirmation with SAED image of confirms the polycrystalline crystalline nature 30–70-nm crystal size. The SEM revealed that modified are well-distributed clusters composed targeted micronutrients. impact nano Fe Zn foliar application was evaluated on rice grain fortification, productivity, efficiency. uptake at 60 days after sowing (DAT) harvest significantly increased mNs rGO-based 30 ppm + 5 as well led fortification by increasing content, through resulted in an improvement yield 53% over conventional fertilization. Besides significant increment yield, (Zn ppm) 527 380%, respectively, fertilization (ZnSO4 FeSO4).
