Impact of engineered nanoparticles on the growth of roots

There is an increasing demand for food and bioenergy crops for growing world population. Conventional fertilizers used for increasing agricultural production are required to be added to the soil in high quantity and have a slow absorption rate in plants. In comparison engineered nanoparticles can be highly attractive as fertilizers as their small size will allow faster absorption. In particular, iron oxide-based nanoparticles will be highly promising as Fe-deficiency fertilizers because iron is required for photosynthesis in plants. We have synthesized iron oxide and hybrid iron oxide as nanoparticle fertilizers to study the significance on root growth of five different seeds: Pisum sativum L, Cicer arientinum, Vigna radiate, and Phaseolus vulgaris. We found iron oxide nanoparticles at low concentration (5.54x10-3 mgL-1 Fe) significantly increased root growth, compared to other growth solutions. This study will be highly useful for increasing agricultural production.
