Amendment of Copper Toxicity in Alluvial Soil Using Iron: Effect on Growth and Yield of Triticum aestivum L.
Pot experiments were conducted in glasshouse under controlled conditions. The effect of copper in alluvial soil on the growth and yield of Triticum aestivum L. (wheat) was worked out. Copper was applied in soil at 5–100 mg L−1, along with iron supplement. Inhibitory response of copper was significant (p < 0.05) confirmed by the plant growth parameters viz., plant height, fresh and dry weight, moisture content, pigment contents, protein, sugar contents followed by increased catalase and peroxidase activity in the harvest at 30, 60, and 90 days, of treatment, respectively. The plants grown on copper treated soil along with 5 mg L−1 Cu and iron application showed significant effects (p < 0.05) regarding the increase in plant biomass, plant height (shoot only), pigment contents, protein, sugar contents, grain yield followed by decreased catalase and peroxidase activity in wheat after 30, 60, and 90 days of treatment, respectively. The accumulation of metal in plant tissues was found in order of Fe > Cu coupled by less translocation in grain as compared to the whole plant.
