The Effect of Ca-Bentonite Aplication on Cadmium Uptake and Shoot Dry Matter of Bread Wheat

Cadmium(Cd) is a non-essential heavy metal that highly toxic even at very low concentrations. Although Cd trace metal, when reached to high levels in agricultural soils, it can be easily absorbed by plants. Cadmium accumulation wheat (Triticum aestivum L.) and its subsequent transfer food chain an important problem worldwide. Bentonite material essentially composed montmorillonite related clay minerals of the smectite group. The purpose this study was investigate effects bentonite (0, 3, 6 12%) application on uptake bread growing 5 10 mg/kg soil) application. Plants were grown under greenhouse conditions acid soil. experiment conducted randomized block design with three replicates. results revealed shoot dry weight significantly increased increasing doses applications. While without 480 mg/plant, approximately 2 fold 12% concentration control decreased 4 times from 20.74 ppm 5.07 bentonite. show toxicity alleviated treatment.
