POTENTIAL IMPACT OF IRON NANOPARTICLES ON GROWTH PERFORMANCE OF PEA (Pisum sativum)

The effect of magnetic ironoxide nanoparticles (IONPs) on the growth and yield of Pea (Pisum sativum) was investigated in the present study. Mature pea seeds were treated with 0.25, 0.50, 1.00 and 5.00 mM concentrated IONPs dispersions. The impact of IONPs on seed germination, plant height, biomass, fruit and seed weight were studied carefully and compared with control. Depending on magnetite particles concentration and soaking time, variable outcome was observed in our experiment. Interestingly, 1.00 mM IONPs showed significant positive impact in all aspects. No significant change was observed in AMF and Rhizobium colonization of Pea which proves the eco-friendly nature of our produced IONPs. IONPs were prepared by coprecipitation of Fe+ and Fe3+ sulfate salts solution (aq) with concentrated sodium hydroxide solution (aq). The particles were surface functionalized with polyethylene glycol. Transmission electron microscopy (TEM) was used for their structural characterization.
