Abstract

During past years, meager information is obtained regarding the plant’s reaction with respect to heavy metal stress induced when the plant is cultivated on various treatment of fly ash in soil. Fly ash is an inorganic solid waste which contain several macronutrients, micronutrients, heavy metals like As, Cr, Cd, Cu, Pb, Ni, Zn etc. which shows harmful effect on the environment, soil, and ultimately human health. Throughout the world, fly ash is produced in huge amounts, and now-a-days it is utilized as soil ameliorants in agriculture, as a building material, in road construction, and in manufacturing of cement. As per reports from various researchers, fly ash amended to soil may improve the physico-chemical properties of soil and which h will ultimately improves the plant growth and yield [1,2]. The heavy metal concentration level in different treatments of fly ash and soil may stimulate or inhibit the plant antioxidant enzyme activity. Several studies are available on fly ash utilization as a soil amendment resulting in enhanced yield and biomass of plant, but fewer reports are available on plant antioxidant potential and oxidative stress when cultivated on different dosage of fly ash.
