Effect of Addition cadmium and lead to the Soil on some vegetative traits and seed content of protien of mung bean plant Vigna radiate L.

Abstract

This study aimed to investigate the impact of cadmium and lead soil contamination on the vegetative growth and protein content of Vigna radiate seeds. The experiment was conducted at the gardens of the College of Education for Women - University of Tikrit during the season 2023. Results indicated that the studied traits were significantly negatively affected by the presence of both elements in the soil, with the highest reduction observed in the treatment with a mixture of 6 mg.kg-1 soil cadmium and 600 mg.kg-1 soil lead. This treatment had the lowest values for vegetative growth characteristics (plant height, number of branches, number of leaves, leaf area, leaf area index, and leaf chlorophyll content) and also had the lowest protein content in the seeds (6.57%). These findings suggest that cadmium and lead contamination in soil can significantly impact the growth and protein content of Vigna radiate plants, with potential implications for crop production and food security.
