Plant growth promoting rhizobacteria accelerate nodulation and increase nitrogen fixation activity by field grown soybean [Glycine max (L.) Merr.] under short season conditions

摘要: A 3 × 2 factorial field experiment, organized in a randomized complete block split-plot with four replications, was conducted 1994 to evaluate the effect of two plant growth-promoting rhizobacteria (PGPR) strains (Serratia liquefaciens 2-68 or Serratia proteamaculans 1-102) on nodulation, nitrogen fixation, and total yield by soybean cultivars short season area. The experiments were at Emile A. Lods Research Centre, McGill University, Macdonald Campus, Montreal, Canada, performed adjacent sites. One site fumigated methyl bromide (50 g m-2). Another kept unfumigated. Co-inoculation B. japonicum PGPR increased nodulation hastened onset when soils still cool. Total fixed N, N as percentage protein also inoculation. AC Bravor tended be more responsive both treatments for yields than Maple Glen, suggesting that inoculation effective higher potentials.
