This study aimed examine the impact of Ascorbic acid spraying once and twice at concentrations 250 and 500 mg/L on the concentration of some nutrients in the seeds of the bean plant (Vicia faba L.) grown on soils contaminated with nickel at concentrations 30 and 60 and lead at concentrations 300, 600 mg/kg soil.The results showed that soil treated with 600 mg/kg lead has a significant decrease of concentration of magnesium, phosphorous, potassium and chloride in the seeds of the bean plants which amounted to 1.16 , 1.121, 4.113 and 0.071 mg/g, respectively compared to the control group. It was also found that spraying the vegetative parts of the bean plant with 250 mg/L ascorbic acid twice was attributed to increasing of magnesium significantly in the seeds of the bean plant, which amounted to 4.00 mg/g. otherwise, spraying with the same concentration, but once, led to a significant increase in phosphorous concentration, which reached 1.335 mg/g. The results also showed that one-time spraying of 500 mg/L ascorbic acid led to a significant increase in chloride concentration, which amounted to 0.395 mg/g compared to the control group. The results show that lead treatment had a more negative effect on the concentration of nutrients compared to the effect of nickel. It was found that spraying with ascorbic acid at a concentration of 250 mg/L was significantly superior to the concentration of 500 mg/L of magnesium, phosphorous, potassium and chloride in the seeds of bean plants. Also, spraying with ascorbic acid once was superior to spraying twice with the concentration of both magnesium and chloride.
