Growth, Yield and Cadmium Accumulation in Wheat Crop (Triticum aestivum L.) as Influenced by Nitrogenous Fertilizer in an Inceptisol of Varanasi, India

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 findings indicated that the uptake of cadmium by wheat crop roots and shoots increased with increasing nitrogen doses up to 180 kg/ha over control. In the case of 5 mg/kg cadmium concentration, the average cadmium concentration 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 was found 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. overall grain yield was increased significantly throughout the experiment, the concentrations of phosphorus, potassium, calcium, and magnesium remained stable. The findings of this study will help agronomists assess the danger of elevated Cd content in various wheat cultivars as a result of regional crop and soil management strategies, particularly those involving nitrogen.
