BIOGENIC SYNTHESIZED Fe3O4 NANOPARTICLES AFFECTON GROWTH PARAMETER OF MAIZE (ZEA MAYS L.)

摘要

In the present research manuscript investigation, nanoscale iron oxide nanoparticles wereprepared using biocombustion method. The biogenic iron oxide nanoparticles (Fe3O4 NPs)are developed as a novel method for application in agriculture field. However, its uptakeand translocation require further study prior to large – scale field application. Thesynthesized Fe3O4 NPs (mean size 21nm) were characterized using techniques like,Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM),Transmission electron microscopy (TEM) and particle size analyzer. The aim of thisinvestigation was to determine the effect of biogenic iron oxide nano particles (Fe3O4 NPs)on yield and quality traits of maize. The crop growth of maize and translocation of ironwere measured to test the effect of Fe3O4 NPs on yield of maize. The results showed thatpretreatment sowing of maize with Fe3O4 NPs at 0.3 mg concentration enhanced 20%germination and improved yield by 20% and 10% yield over control. Similarly, comparedto control, Fe3O4 NPs pretreatment sowing caused an increase by 20% in cob weight, 10%in average tassel length and 15 % in the average plant height. Therefore, the present studyshowed that Fe3O4 NPs at 0.3 mg results in an enhanced yield, seed quality traits of maizeunder field conditions.
