Abstract
The influence of soil amendments (spent coffee grounds, bone meal, sewage sludge) on cadmium (Cd) and zinc (Zn) accumulation and growth performance of marigold (Tagetes erecta L.) varieties–Prime yellow, Twenty yellow and Dragon yellow–was evaluated. X-ray fluorescence was applied to determine the elements in tissues of cross-sectioned stems. Twenty yellow showed the highest percentage tolerance index values (151%) and percentage growth rate in dry biomass (164.2%) in Cd/Zn-amended treatments. The sewage sludge improved soil quality and promoted plant growth and also contributed to high Zn and Cd accumulation in Dragon yellow leaves (221.3 and 57 mg kg<sup>−1</sup>, respectively). Dragon yellow variety exhibited potential for Cd phytoextraction potential as indicated by a bioconcentration factor for shoots >1 and translocation factor >1. In Dragon yellow grown in soil amended with BM, Cd and Zn were detected primarily in the epidermis and cortex. This may have resulted from the high P concentration in BM-supplemented soil, which increased co-precipitation of metals with P in epidermal cell walls. The enhancing properties of certain soil amendments can benefit marigold growers, as specific materials were found to support the growth of certain marigold varieties (for example, SS is considerably compatible with the Dragon yellow variety).
