Impact of Fortified Nano Zinc and Iron Composite Capsules on Growth, Yields and Nutrients Accumulation in Cabbage (Brassica oleracea var. capitata L.) and Cauliflower (Brassica oleracea var. botrytis L.)

Synthesized composites were characterized through UV-spectrophotometer, XRD, SEM, EDX and FTIR analysis. SEM images confirmed surface morphology of ordinary mesoporous nano silica (mNs) Fe & Zn embedded mNs. In XRD pattern mNs peaks absence indicate that synthesized by sol-gel method was amorphous whereas reduced graphene oxide (rGO) in crystalline form. spectra loaded rGO showed encapsulation zinc iron mNS successful. Results experiment indicate, twice foliar application 60 ppm Zn+ 30 (T6) 40 Zn+20 (T8) exhibited significantly higher economic biological yields both crops over conventional Control. With increasing doses composite capsules, significant increase nutrients content uptake cabbage cauliflower observed comparison to control. Whereas, lead a considerable reduction nutrient thus hamper their uptake. Thus, T6 T8 treatments best pronounced terms yields, enriching biomass cauliflower, respectively. Compared control, quality head curd content, protein phenol more with Zn+30 , Available soil unaffected crops.
