Effect of Rhizobium japonicum in Relation to Nodulation and Chlorophyll Content of Soybean

The soybean (Glycine max), commonly called 'Cindrella crop' or 'king of legumes' R. japonicum is the symbiotic microorganism which forms ischolar_main nodules on the ischolar_mains of soybean to fix atmospheric nitrogen. The seeds of soybean were coated with R. japonicum to prepare legume inoculants.These seeds were referred as treated seeds.The treated seeds and untreated seeds were sown in the field. After 15 days of sowing of treated seeds and untreated seeds,the nodulation was checked. It was noted that treated seeds shown more nodules as compaired to untreated seeds. The investigation was again carried out to check the effect of R. japonicum in relation to chlorophyll content.The plants arrised from treated seeds shown high chlorophyll content as compaired to the plants arrised from untreated seeds.
