Dinitrogen fixation of rice-Klebsiella associations



Dinitrogen fixation of rice-Klebsiella associations



Crop Science 26(2): 297-301



N2 fixation by Klebsiella oxytoca strain NG13, isolated from the rhizosphere of a rice plant, in association with indica type rice strain, C5444 is reported. Acetylene-reduction assays, biomass measurements, N content determinations and 15N isotopic dilution assays indicated that inoculation of C5444 with NG13 resulted in a 6% increase of total plant + soil N content and a 19% 15N isotopic dilution of plant N after 120 days of cultivation.
