Effect of Organic Matter on the uptake of Cadmium by Spinach (Spinaceaoleracea L.)

A field experiment was conducted to find out the effect of organic matter on the uptake of cadmium by Spinach (Spinaceaoleracea L.) on the alluvial soil of Sheila Dhar Institute experimental farm, Allahabad. Three levels of organic matter (0, 10 and 20 t ha-1), Cd (0, 5 and 10 mg kg-1) were applied as compost and CdCl2, respectively. Addition of 20 t ha-1 organic matter increased the maximum dry biomass yield of Spinach by 36.5% over the control. The application of 10 mg kg-1 Cd maximum reduces dry biomass yield of Spinach by 27.8% over the control and registered the highest accumulation of Cd in shoot of Spinach by 5.7 fold over the control. Therefore, 20 t ha-1 organic matter applications may be recommended to enhance biomass yield of Spinach and Phytoremediation of Cadmium?contaminated soil through soil-plantrhizospheric processes.
