Impact of fly-ash amended soil on growth and rhizome setting in an endangered medicinal plant Acorus calamus Linn.

Fly-ash, the Coal Combustion Residue is a problem for environment but has been proven to be effective in agricultural production because of its alkaline nature, rich nutrient content, and occurrence of micro and macro-elements. Under the view of the fact that fly-ash may prove to be a better nutrient supplement for plants when amended in soil. Thus the effort was made to conduct an experiment on the effect of Fly-ash amended soil on an endangered medicinal plant Acorus calamus Linn. of family Araceae. This paper deals with the growth and rhizome setting performance of Acorus calamus Linn. (Araceae) in different levels of amendments of common field soil with fly-ash. The findings revealed that the lower doses (10-20%) of fly-ash are beneficial to the growth of the plant. Over all, this study indicates that fly-ash amendment of soil may increase the productivity of Acorus calamus and maygo a long way in conservation of this endangered plant.
