“…As was observed in our study, a large body of evidence shows that PGPR enhance the growth, seed emergence and crop yield, and contribute to the nutrient enrichment of plants (Dey et al, 2004;Kloepper et al, 2004;Herman et al, 2008;Minorsky, 2008). Salamone et al (2012) reported that PGPR inoculation reduced the chaffy grain percentage in rice plants; a 10% increase in grain number in wheat in response to PGPR treatment was reported by Rana et al (2012); also higher number of grains in lentil plants were reported by Zafar et al (2012) in response to bacterial inoculation; in another experiment increased grain number was reported in cowpea plants in response to PGPR treatment by Minaxi et al (2012). …”

“…IAA production and P solubilization resulting in an increase in the root and shoot length, fresh weight, dry weight, nutrient uptake has been reported in lentil (Zafar et al, 2012) and cowpea (Minaxi et al, 2012). However, in case of rice increased root length, shoot length, aerial biomass and increased nutrient uptake has also been reported in response to the PGPR application (Salamone et al, 2012).…”

Plant growth promoting rhizobacteria (PGPRs) improve growth of the host plants in a variety of ways. For this reason five bacterial strains isolated form the rice rhizospheric soil (B 15, B 17, B 19, BN 17 and BN 30) and three standard PGPR strains (viz. Pseudomonas putida, Pseudomonas fluorescens and Azospirillum lipoferum) were tested for plant growth promotion when applied to the rice plants as seedling treatments. The experiment was conducted for two rainy seasons of the years 2010 and 2011. Rice plants inoculated with the bacterial isolates recorded an improved plant growth and higher photosynthetic capacity signified by the higher chlorophyll content. Root and shoot dry mass was also found to be increased in the inoculated plants. Besides these iron and zinc content of the treated rice plants was also found to be higher in comparison with the uninoculated control plants. Hence, it can be concluded that application of PGPR has immense potential to be used as agricultural crop inoculants as they promote plant growth as well as improve the health and yield of the plants.

“…The higher germination rate observed in inoculated treatments during this experiment may be due to plant growth promoting activities of the 2 bacterial strains. Although at this stage the germinating seeds receive most of the nutrients from seed reserves, plant growth hormones such as auxin or gibberellic acid produced by rhizobacteria may act as stimulants (Minaxi et al, 2012).…”

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.

“…A significant increase in growth and yield of cowpea and other important crops in response to seed bacterization with PGPRs have been reported by many workers (Amara and Dahdoh, 1997;Asghar et al, 2002;Minaxi et al, 2012). This considerably reduces the input cost on fertilizers and pesticides.…”

Plant growth promoting rhizobacteria have been used to improve crop production. A total of 114 bacterial isolates were recovered from the rhizosphere soils of healthy plantation and vegetable crops grown in Andaman Islands. These isolates were evaluated in vitro for plant growth promoting traits, hydrolytic enzyme production and antagonistic activity. Among the isolates, NPB6 and MNB1 were positive to 8 out of 10 properties tested followed by NFB3, MKP3, NNB4 and NTB2. In the dual culture assay, NFB3 showed highest inhibition against the plant pathogen Macrophomina spp (33.3%) and S. rolfsii (23%). Six most promising isolates were selected and identified as Bacillus and Pseudomonas spp. on the basis of Microbial Identification System and 16S rDNA. These isolates significantly increased the seed germination, vigor index, radical and plumule length however, the individual isolates effect varies with crop. All the six isolates enhanced the root and shoot length of brinjal, chilli and okra seedlings while Bacillus cereus (NPB6) in brinjal, B. stratosphericus (NFB3) in chilli and Pseudomonas fluorescens (NNB4) in okra were most effective. The promising isolates can be used in combination with other beneficial native microbes for plant growth promotion even under abiotic stresses and promotion of organic agriculture.
