The Effects of Iron Oxide Nanoparticle (FeO-NP) Application on the Growth of Bean (Phaseolus vulgaris L.) Grown in Soilless Culture
Journal Title: ISPEC Journal of Agricultural Sciences - Year 2023, Vol 7, Issue 4
Abstract
In order to increase the Fe content of plants grown on iron-deficient soils and to reduce the health problems associated with Fe deficiency in humans and animals, there is a need for effective, cheap and environmentally friendly fertilizer production and fertilizer applications. In this study, iron oxide nanoparticles (FeO-NPs) synthesized by green synthesis method were characterized and applied in increasing doses (0, 2, 4, 6, 8 and 10 mg L-1) to Hoagland nutrient solution in which beans (Phaseolus vulgaris L.) were grown. The experiment was carried out in three replicates for 30 days in a climate chamber with controlled conditions (16/8 hours’ light/dark, 25/20 °C temperature and 60 % humidity, 10 Klux light intensity). Throughout the experiment, we observed morphological changes in bean plants grown in perlite culture, measured chlorophyll content in leaves before harvest, and determined dry weight of shoots and roots and concentrations of Fe, N, P, K, Ca, Cu, Mn, and Zn in shoots parts. The application of FeO-NP has exhibited a significant impact on the concentration of Fe in both the shoots and roots according to the results obtained (5 % and 1 %, respectively). The highest Fe concentration (92.11 mg kg-1) in the shoots was determined from the 10 mg L-1 application dose. With FeO- NP application, the dry weight of shoots as well as the concentrations of N, Mg, and Cu decreased in comparison to the control, while the concentrations of P, K, Ca, Zn, and Mn varied depending on the dosage of the application. Except for nitrogen, the study established that the macro and micronutrient concentrations in plant tissues were sufficient.
