In a sol. culture experiment, the effect of S and N on shoot and root wt., nodulation and nitrogenase activity was studied in lucerne Saranac seedlings inoculated with a very efficient strain of Rhizobium meliloti. Shoot and root wt. and nodulation index increased with increasing N and S conc. The rate of increase of shoot wt. and nodulation index was not constant over the range of S conc. studied. There were S X N interactions on shoot and root wt.
