Abstract

A pot experiment was conducted to explore the growth, yield and cadmium accumulation in wheat Crop(Triticum aestivum L.) as Influenced by nitrogenous fertilizer in an Inceptisol of Varanasi, India. The findingsindicated that the uptake of cadmium by wheat crop roots and shoots increased with increasing nitrogendoses up to 180 kg/ha over control. In the case of 5 mg/kg cadmium concentration, the average cadmiumconcentration content increased by 0.3, 0.4, and 0.633 at 60,120, and 180 kg/ha, respectively, over control.At Cadmium 10 mg/kg concentration, there was a similar degree of progress. Cadmium accumulation wasfound more in roots than shoots. However, with increasing nitrogen rates, crop growth, chlorophyll content,and spike length all increased significantly. The tillers per plant and grains per ear or spike, i.e. overallgrain yield was increased significantly throughout the experiment, the concentrations of phosphorus,potassium, calcium, and magnesium remained stable. The findings of this study will help agronomistsassess the danger of elevated Cd content in various wheat cultivars as a result of regional crop and soilmanagement strategies, particularly those involving nitrogen.
