The effect of iron, potassium, calcium and manganese nano chalate spray on the amount of elements and enzymatic activity Mentha piperita

This study was designed and conducted to investigate the effects of foliar application of Iron, Potassium, Calcium and Manganese nanoparticles on the amount of elements and enzymatic activity of peppermint (Mentha piperita) in a completely randomized design in experiments. Plants were sprayed with three levels of Iron, Potassium, Calcium and Manganese nanoclates (2, 4 and 6 ppm) and the experiment consisted of 13 treatments, each with 3 replicates, each replicate containing 3 plants and a total of 117 pots were examined. In this study, 4 to 6 leaflets peppermint transplants were cultured in appropriate media (peatmoss, sand and clay at a ratio of 1: 1: 1). Foliar application was performed three times a week and after two weeks, sampling and evaluation of traits including superoxide dismutase and peroxidase activity, Iron, Ppotassium, Calcium and Manganese content and essential oil percentage were determined. The results showed that in experiment, the effect of treatment on Iron content had significant difference at 5% and other traits at 1%. Also the highest level were observed in traits such as superoxide dismutase and peroxidase enzymes activity and leaf Iron content in iron nanoclates 6ppm treatment, maximum Potassium content in potassium nanoclates 6ppm treatment, highest The amount of Manganese in manganese nanoclates 6ppm treatment, the highest Calcium leaf content in calcium nanoclates 6ppm treatment and the highest essential oil percentage in iron nanoclates 4ppm treatment. The lowest of all traits evaluated was in control treatment.
