A. Crotalaria juncea
B. Sesbania aculeata
C. Sesbania rostrata
D. Cyamopsis tetragonoloba

Answer

C

Explanation

Sesbania rostrata is a small semi - aquatic leguminous tree. It forms a symbiotic relationship with gram negative rhizobia which leads to the formation of nitrogen fixing nodules on both stems and roots. It is mainly used as green manure to improve soil fertility due to its fast growth, high biomass production and ability to convert large amounts of atmospheric nitrogen into a usable form for plants.
