Effect of compost and single super phosphate on the uptake of cadmium by Radish (Raphanus sativus L.)

A field experiment was conducted to find out the effect of organic matter and single super phosphate on the uptake of cadmium by Radish (Raphanus sativus L.) on the alluvial soil of Sheila Dhar Institute experimental farm, Allahabad. Three levels of organic matter (0, 10 and 20 t ha(-1)), single super phosphate (0, 100 and 200 kg ha(-1)), Cd (0, 5 and 10 mg kg(-1)) were applied as compost, SSP and CdCl2, respectively. Addition of 200 kg ha(-1) SSP increased the maximum dry biomass yield of Radish by 31.7% over the control. The application of 10 mg kg(-1) Cd maximum reduce dry biomass yield of Radish by 17.5% over the control and registered the highest accumulation of Cd in shoot and root of Radish by 2.0, 2.4 fold over the control, respectively. Therefore, 200 kg ha(-1) SSP applications may be recommended to enhance biomass yield of Raphanus sativus L. and phytoremediaton of cadmium-contaminated soil through soil-plant rhizospheric processes.
