Abstract:
Different plant growth-promoting rhizosphere (PGPR) bacteria, including associative bacteria such as Azospirillum, Bacillus, Pseudomonas and enterobacter group have been used for their beneficial effects on plant health. Several studies clearly showed the effect of PGPR on health of different crops at different climates, soils and temperatures. Rhizosphere bacteria Pseudomonas spp., Azospirillum spp., Pantoea spp., Agrobacterium spp., increases plant growth and nutrient uptake of wheat, maize and legumes in moderate climates. PBW274 when treated with isolated PGPR2 and PGPR3 showed non-significant effect over uninoculated control, while isolated PGPR1 and mixture of PGPR1, PGPR2 and PGPR3 showed significant effect (10.06 cm and 10.53 cm). In this study, all these three isolates showed better performance in comparison to un-inoculated control.
