Abstract: In symbiosis with Rhizobium sp,most leguminous plants form nitrogen-fixing nodules on their roots,Recent progress has been made in the research of stem-nodulated plants whose dual nodulation confers upon them an unusually high nitrogenfixing potential.They mainly belong to three genera:Sesbania,Aeschynomene and Neptunia.The object of this paper is to review the available informaton on stem nodule and its application,with special emphasis on Sesbania rostrata.

Key words: Stem-nodule, Stem-nodulated plant, Nitrogen fixation
