ABSTRACT
In the present scenario, cadmium toxicity is one of the major problems in the agricultural field. A higher concentration of Cd is toxic to plants and causes a reduction in plant growth and biomass. Cadmium toxicity can reduce photosynthetic pigments, respiration, and water relations and cause oxidative damage and lipid peroxidation in plants. In the literature, several methods have been described to mitigate the effect of cadmium toxicity in plants. Silicon is present prominently in the environment, but it is not considered an essential element for plant growth and development. However, many studies have shown the positive effects of Si on the growth and physiology of plants, especially under biotic and abiotic stresses, including Cd
