t0“Low survival of Rhizobium japonicum inoculant leads to reduced nodulation, nitrogen fixation and yield of soybean”
e0“When the plots were re-sown in 1983-84, nodulation, growth and yield of the crops, irrespective of the initial rhizobial status of the soil, were equally good, and there was no response to further inoculation”

Other claims from this paper (8)
- Intervention effect In the 1982-83 crop, foliage and seed nitrogen content was reduced in rhizobia-low soil relative to rhizobia-high soil.
- Intervention effect In the 1982-83 crop, nodulation was lower in rhizobia-low soil relative to rhizobia-high soil.
- Intervention effect Inoculation rate did not affect nodulation in rhizobia-high plots.
- Intervention effect Production of foliage and seed nitrogen was satisfactory irrespective of inoculation rate in rhizobia-high plots.
- Observation In the 1983-84 crop, nodulation, growth and yield were equally good irrespective of the initial rhizobial status of the soil.
- Observation In the 1982-83 crop, less than 1% of the inoculant survived the first day after sowing.
- Observation A substantial population of R. japonicum developed between seasons in the rhizobia-low plots.
- Mechanism Poor nodulation of first-year soybean crops is a likely consequence of failure to establish adequate numbers of R. japonicum in the soil at sowing.
