To investigate the potential of inoculation technologies to improve the nitrogen fixation and/or production of field pea
The Hart field site has a background of pea rhizobia that are numerous, but only moderately effective. Inoculation treatment did not affect measured root parameters. Some inoculation treatments increased shoot biomass and pod number, but not grain yield or grain N content. The N benefit from the extra biomass residues is estimated to be 51 kg N/ha
