Effects of Nitrogen and Zinc Fertilization on Alleviating Cadmium Accumulation in Durum Wheat Grains

Cadmium (Cd) accumulation in durum wheat (Triticum L.) is of particular concern compared to the other commonly cultivated cereals. This study was conducted determine effects zinc (Zn) and nitrogen (N) applications on grain Cd concentration grown a contaminated soil. The experimental design consisted randomized plots with four replications. treatments included low adequate (0.05 5 mg kg−1) Zn doses, inadequate, optimal high (200, 400 600 N doses. application rates were 0 kg−1. findings demonstrated that caused significant increase concentrations, decrease straw yields under doses all However, increasing soil an concentration. optimum treatment 6206 µg kg−1, while decreased by 26.3% (4574 treatment. In addition, conditions application, whereas increased results revealed combined deficient soils highly effective at decreasing grains individual applications.
