Common bean seeds of three cultivars were inoculated with Rhizobium singly or in a
combination with PGPR to evaluate their effect on growth characters. A significant variation
of plant growth in response to inoculation with Rhizobium strains was observed. Treatment
with PGPR significantly increased pod per plant, number of seeds per pod, weight of 100
seed, weight of seeds per plant, weight of pods per plant, total dry matter in R6 as well as
seed yield and protein content. Co-inoculation with Rhizobium and PGPR demonstrated a …

To study the effect of co-inoculation with plant growth-promoting rhizobacteria (PGPR) and
Rhizobium, on yield and yield components of common bean (Phaseolus vulgaris L.)
cultivars was investigated in 2 consecutive years under field condition of plant growing
evidence indicates that soil beneficial bacteria can positively affect symbiotic performance of
rhizobia. PGPR strains Pseudomonas fluorescens P-93 and Azospirillum lipoferum S-21 as
well as two highly effective Rhizobium strains were used in this study. Common bean seeds …
