RahmaniH.A. NoormohammadiG. AynebandA. 1220081115To 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 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 significant increase in the yield and yield components.
The results showed that all treatments of bacteria increased yield; however,
strains Rb-133 with Pseudomonas fluorescens P-93 gave the highest
seed yield, number of pods per plant, weight of 100 seed, seed protein
yield, number seed per pod, seed protein yield.]]>Ahmad, F., I. Ahmad and M.S. Khan,2008168173181Asadi Rahmani, H., M. Afshari, K. Khavazi, F. Nourgholipour and A.
