Abstract

Rare earth elements (REE) are found to be beneficial to plants in order to improve crop yield. The present study reveals the response of leguminous plant (Arachis hypogaea L.) to monazite soil containing Rare earth elements (Lanthanum and Samarium). This particular study explains the effects of rare earths on factors such as growth, total leaf chlorophyll content, number of root nodules and nitrogenase activity of groundnut plant. A significant increase in plant biomass and total chlorophyll content are observed. The increase in number of root nodules and the nitrogenase activity (Acetylene reduction, 20.72 n moles C2H4 formed / h/ g fresh nodules) were observed in the plants exposed to REEs. A profound effect of Lanthanum and Samarium present in the rare earth soil on the chlorophyll content, amylase activity, SOD and POD level were noticed
