Abstract: (38 Views)
Reliance on chemical fertilizers during the Green Revolution significantly increased agricultural productivity but also led to substantial environmental challenges. Nano-fertilizers, applied either to soil or leaves, enhance crop growth, yield, and quality by improving nutrient utilization, reducing fertilizer waste, and lowering cultivation costs. Foliar application, particularly beneficial under adverse soil and weather conditions, facilitates direct nutrient uptake by plants and minimizes losses. Therefore, this study investigated the effect of nano-potassium (NP) fertilizer (0.1 mg.ml-1) on some physio-biochemical traits of peppermint under salinity conditions (0, 50, 100, and 150 mM NaCl). The experiment was conducted in 2023 using a factorial design based on a completely randomized design with three replications. The results indicated a significant decrease in physiological and photosynthetic parameters in plants under salinity treatment. However, nano-potassium improved salinity tolerance in peppermint plants by improving these physiological and photosynthetic parameters, as well as increasing the content of osmolytes (such as proline) and reducing stress markers (such as hydrogen peroxide and malondialdehyde) in plant tissues. Based on the physio-biochemical findings of this study, NPs fertilizer has a considerable ability to ameliorate damages produced by salinity treatment in peppermint plants under medium saline soils.
