Abstract :

A field experiment was conducted to find out the impact of single super phosphate (SSP) on the uptake of cadmium by Carrot (Daucus carota L.) on the alluvial soil of Sheila Dhar Institute experimental farm, Allahabad, Uttar Pradesh. Four levels of SSP (0, 100, 150 and 200 kg ha-1) and Cd (0, 5, 10 and 15 mg kg-1) were applied as SSP and CdCl2, respectively. The application of SSP 200 kg ha-1 increased the dry biomass of Carrot by 26.50% over the control. The application of 15 mg kg-1 Cd maximum reduces dry biomass of Carrot by 17.70% compared to control and registered the highest accumulation of Cd in shoot and root of Carrot by 1.80 and 2.56 mg kg-1, respectively. Application of Cd 10 mg kg-1 + SSP 200 kg ha-1 decreased maximum bioaccumulation factor (BFs) of Cd 0.055 in Carrot, compared to non-amended plot. Therefore, 200 kg ha-1 SSP application may be recommended to enhance dry biomass of Carrot. The response of SSP was observed ameliorative in Cd-contaminated plots.
