Nodulation of soybeans in pot culture by effective and ineffective strains of Rhizobium japonicum
1937
Ruf, E.W. | Sarles, W.B.
Pot experiments with Manchu soybeans performed in both fall and spring showed that three effective strains of Rhizobium japonicum (Nos. 9, 18, and 505) produced relatively few, large nodules, the majority of which were located on, or in the immediate vicinity of, the tap root near the surface of the soil. The ineffective strain used (No. 507) produced many small nodules that were scattered over the entire root system. The ineffective strain produced a greater number, volume, and weight of nodules on each plant than the effective strains. The relative effectiveness of the strains used was determined by comparing the dry weight and nitrogen content of plants grown from inoculated seed with that of plants grown from uninoculated seed.
