Abstract

Groundnut (Arachis hypogaea L) is a leguminous plant which is symbiosis with nitrogen fixing bacteria such as Rhizobium. During drought condition such as water stress, the plant is affected both chemically and physiologically. In this present study the Rhizobium was isolated and purified from Arachis hypogaea L in natural conditions and inoculum were stored for further study. The Arachis hypogaea L seeds were cultivated in lab conditions as both control and inoculated with Rhizobium. Both inoculated and control seeds were cultivated for several days by inducing water stress. After the investigated days the morphometric characters, nitrogenase activity and Leghaemoglobin content of both control and inoculated plants were determined in which the inoculated plants showed resistance towards the water stress and yield is high when compared to control plants during water stress.
