Phytoremediation is an excellent technique that utilizes green plants for the partial degradation of heavy elements found in soil. Plants utilize a diverse range of biological and physical properties to assist in managing pollution. This study proceeded to investigate the effect of iron nanoparticles and titanium for phytoremediation and their impact on the growth and physiological traits of potato (Solanum tuberosum L.). A field experiment on potato, carried out in the spring of 2021 at the University of Anbar, Al-Anbar, Iraq, used various combinations of titanium and iron nanoparticles. The results revealed treatment T7 (100 mg kg-1 Ti soil + 150 mg kg-1 FeNPs) outperformed in plant height, number of stems, leaf area, dry weight, and percentage of nitrogen, phosphorus, and potassium, with rates of 1.92%, 0.58%, and 1.85%, respectively, compared with the control treatment. The study further disclosed treatment 100 mg kg-1 Ti soil + 150 mg kg-1 FeNPs positively affected the physiological traits of the potato crop.
Potato (S. tuberosum L.), phytoremediation, iron nanoparticles, titanium, growth and physiological traits
Iron nanoparticles and titanium dioxide enhanced vegetative growth, improved element levels, plant vegetative and physiological traits of potato (S. tuberosum L.), and treated the soil pollution. Additionally, employing varying concentrations of iron nanoparticles in plant treatment exhibits promise for remediating contaminated soils.
