Synthesis of nano materials on the base of rice husk ash and CeO2 for application as a growth stimulant for bell peeppers plan (capsicum annuum L.)

Abstract

In this study, CeO₂/SiO₂ material was synthesized and applied as a growth stimulant for bell pepper plants from Ce(NO₃)₄ precursor and rice husk ash using gamma irradiation method. Material morphology and structure were confirmed through physicochemical characterization methods including: XRD, EDX, IR and SEM characterization. The results of surveying the effects of CeO₂/SiO₂ materials on the growth and development of bell pepper plants show that CeO₂/SiO₂ significantly affects the growth and development of bell pepper plants. Experimental data obtained showed that bell pepper yield increased by 22 tons/ha, average root length increased by 3.6 cm and harvest time was 11 days less than the control sample. In addition, bell pepper plants supplemented with CeO₂/SiO₂ are stronger and do not have yellow leaves. This shows that CeO₂/SiO₂ has a growth stimulating effect on bell pepper plants.
