The Accumulation Of Cadmium In Corn (Zea Mays L.) At Different Levels Of Soil Ph

Abstract

A pot experiment was carried out in the plastic greenhouse at the Institute of Sustainable Agrotechnology (INSAT), Universi ty Malaysia Perlis in Sungai Chuchuh, Perlis, Malaysia. During season of the cultivation of 2014 investigate the impact of soil pH and cadmium on growth of corn plant (Zea mays L.). Twen ty five were arranged in factorial experiments according to the Complete Randomized Design (CRD), with three replicates. Five levels of soil pH were, pH4, pH5.2 (i.e., the original value), pH6, pH7 and pH8 and five levels of cadmium (Cd); Cd 1, Cd 2, Cd 3, Cd 4 and Cd 0 where the amounts (2, 4, 6, 8 mg. kg-1 soil and control treatment without add cadmium) are applied as CdCl2. Thus, the total numbers of pots were 75 pots. The results of this investigation revealed that; The decrease of soil pH led to signif icant effect to increase concentration of cadmium in root, stem, leaves and grain of corn, where the level of pH 5.2 gave high est concentrations of Cd compared with pH 8. the interactions between soil pH and cadmium led to increase of reduced the accumulation of cadmium in the corn, where it gave the interac tion between pH 8 and Cd 0 lowest concentration of cadmium in root, stem, leaves and grain
