“…It shows that the introduced bacteria could survive, proliferate and colonize the rhizosphere of plants. The results are in close conformity with those reported by Reid (1990) and Barea et al (2005). The PSB abundances were either higher or comparable to the bioinoculant treated wheat plant rhizosphere, when compared with commercial biofertilizer which shows their better survival capability.…”

The present communication is an attempt to explore the synergistic effect of two indigenous phosphate solubilizing bacteria (PSB) (Pseudomonas fluorescens BAM-4 and Burkholderia cepacia BAM-12) and arbuscular mycorrhizal (AM) fungus, Glomus etunicatum on growth, yield and nutrient uptake of wheat plants grown in nutrient deficient soils in pots amended with tricalcium phosphate (TCP). A significant increase in growth, yield and nutrient uptake of wheat plants was noticed and both strains of PSB interacted positively with AM fungus towards all growth parameters studied. A remarkable enhancement of seed yield was recorded notably by 92.8% and an increase in percent root colonization of AM and PSB population in soil was also recorded with time.

“…The benefits of growthinducing bacteria to plants include stimulation of the plants growth by rhizosphere bacteria through fixing atmospheric nitrogen, increasing the availability of nutrients in rhizosphere, increasing root contact area, producing growth regulators and improving beneficial symbiosis with host plant at different growth stages (Chogan, 2003). Through improving the ability of host plant in absorbing nutrients, such as N and P in particular, from unavailable resources and augmenting the activity of soil microbial community, mycorrhiza and rhizobia increase the plant hormones like auxin and enhance the waterdeficit resistance (Zahir et al, 2000;Barea et al, 2005). Given the fact that the application of chemical fertilizers is accompanied by the pollution of soil and environment, the application of biological sources for improving the tolerance and performance of the plants can be regarded as the useful economic, social and environmental aspects of these materials.…”

Water deficit is one of the most important environmental stresses that adversely affect crop growth and production and mycorrhizal fungi and symbiotic bacteria have important role in resistance to drought stress. The effect of biofertilizers on alfalfa stress tolerance was studied at the greenhouse condition. Treatments comprised three water-deficit stresses (35%, 55% and 75% of field capacity) and four seeds inoculations (Glomus mosseae, Sinorhizobium meliloti, G. mosseae + S. meliloti and non-inoculated). Water-deficit stress decrease cell membrane stability (39%), total Chl (24.05%), carotenoid (35.55%), quantum yield (50.64%) and forage yield (28.20%), while increased the proline and soluble sugars content (68.55 and 46.53% respectively) and osmotic potential (45.84%). The inoculation of seeds increased the capability of the plants in counteracting the stress, so that the production of compatible solutes was increased and the photosynthetic indices, proline, osmotic potential, membrane stability and forage yield were improved by seed inoculation. Mycorrhiza improved photosynthetic indexes and proline, but bacteria had more efficacy on membrane stability and forage yield. However, double inoculation due to the synergistic effect of mycorrhiza and Sinorhizobium, had the greatest effect than Solitary inoculation. Our results suggest that biofertilized alfalfa plants were better adapted than non-biofertilized ones to cope with water deficit.
