Abstract :

Due to the importance of using nanotechnology in sustainable agriculture to increase the quantitative and qualitative yield of agricultural products, This study aims to investigate the effect of foliar application of iron, potassium, calcium and manganese nanoparticles on some morphophysiological traits and nutrient uptake of peppermint (Mentha piperita L.) that is one of the most important medicinal plants of the lamiaceae family was done in a completely randomized design with three replications in 2018 in a greenhouse located in Islamshahr. Foliar application treatments of iron, potassium, calcium and manganese nanoclates included three levels of 2, 4 and 6 mg/l. Foliar application was applied in three stages with one week intervals and two weeks after the last foliar application, sampling was performed to evaluate the traits. The results showed that the application of nano-chelates significantly increased the evaluated traits compared to the control, so that the highest fresh and dry weight of shoots, total chlorophyll content of leaves and iron in the treatment of iron nano-chelate 6 mg/l, the highest fresh and dry weight of roots and the amount of potassium in the treatment of nano-chelate potassium was obtained 6 mg/l, also the highest amount of phenol and manganese in the treatment of nano-chelate manganese 6 mg/l, the highest amount of flavonoids and vitamin C in the treatment of nano-chelate Manganese 4 mg/l, the highest amount of calcium was observed in the treatment of calcium nano-chelate, 6 mg/l and the highest amount of essential oil was observed in the treatment of iron nano-chelate, 4 mg/l. In general, according to the results of this study, the application of iron, potassium, calcium and manganese nano-chelates with concentrations of 4 and 6 mg/l has a positive effect on increasing the productivity of peppermint.
