In order to evaluate the effects of foliar application of nano fertilizers on germination and seedling growth indices of pea under heavy cadmium stress, a factorial experiment based on a completely randomized design with four replications was conducted at Mohaghegh Ardabili University in 2019. In this study, in addition to seed germination and seedling growth indices of pea, some biochemical parameters such as soluble protein content, proline, and the activities of antioxidant enzymes catalase and peroxidase were measured. The experimental treatments included five foliar application levels (control, foliar application with molybdenum 2 parts per thousand, foliar application with molybdenum 4 parts per thousand, foliar application with boron nanochelate 2 parts per thousand, foliar application with boron nanochelate 4 parts per thousand) and three cadmium stress levels (0, 50, and 100 mg/L cadmium chloride). The results showed that cadmium stress significantly reduced the germination percentage and rate, seedling length and dry weight, and increased antioxidant enzymes, protein and proline. Severe cadmium stress (100 mg/L) reduced the germination percentage by 16.4%, germination rate by 66.51%, seedling length by 07.43%, seedling dry weight by 33.43%, and catalase by 14.57%, peroxidase by 15.31%, protein by 65.89%, and proline by 09.10% compared to the control. While feeding with boron and molybdenum nanochelate fertilizers increased germination indices by about 42.20% and seedling growth (length and dry weight) by about 92.58%, through increasing growth and activity of antioxidant enzymes such as reduced the effects of cadmium stress.
