t0“Low survival of Rhizobium japonicum inoculant leads to reduced nodulation, nitrogen fixation and yield of soybean”
e0“This did not affect nodulation in rhizobia-high plots and production of foliage and seed nitrogen was satisfactory, irrespective of rate of 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 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.
- Intervention effect In the 1983-84 crop there was no response to further inoculation.
- 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.
