Antagonistic effect of calcium (Ca2+) on cadmium (Cd) viz. chlorophyll, protein and oil yield of mustard plant (Brassica juncea L.) var. pusa bold

The Current study was conducted to study the antagonistic effect of Calcium (Ca2+) on Cadmium (Cd) in the soil in which mustard (Brassica juncea L.) var. Pusa Bold was cultivated. The treatment of Ca-Cd was given to the soil after 15 days of seed sowing. The Cd-toxic treatment showed retarded growth, photosynthesis, protein content, yield and oil content as well as chlorsis of young leaves, such symptoms were not observed in Ca- alleviated plants. Ca2+ alleviated plants showed higher growth, photosynthesis, protein content, yield and oil content. The lowest growth was found in the higher concentration of Cd (1200ppm/plot). However when Ca was applied, it was found that it compensate the effect of Cadmium in low concentration but when higher Cadmium concentration was present, Ca was ineffective to compensative the effect of Cd.
