“…Bacterial strains IESDV12 (30.58 and 34.91 lg/ml), IESDV11 (18.71 and 32.08 lg/ml), IESDV26 (30.10 and 31.28 lg/ml) and IESDV27 (24.80 and 32.53 lg/ml) showed more statistically significant IAA production in broth culture at 150 and 300 lg/ml tryptophan concentrations, respectively. In support of present results, different scientists found that the IAA production by various microbial strains has ability to show the IAA activities varied within species and/or strains of the same species (Abbasi et al 2011;Quadt-Hallmann and Kloepper 1996;Verma et al 2010Verma et al , 2013. Others strains, IESDV2 (22.56 and 23.19 lg/ml), IESDV3 (23.57 and 26.61 lg/ ml), IESDV4 (20.03 and 25.28 lg/ml), IESDV5 (21.02 and 22.54 lg/ml), IESDV10 (25.61 and 22.30 lg/ml) and IESDV28 (20.27 and 23.68 lg/ml), also found more significant enhancement in IAA production than other strains at 150 and 300 lg/ml tryptophan concentrations, respectively (Table 6).…”

The current study was intended to isolate and characterize the plant growth-promoting properties and pesticide (chlorpyripfos) tolerance ability of microbial strains for sustainable vegetable productions. Plant growthpromoting microorganism is a group of microbial consortia to improve crop growth and yield by various direct mechanisms, e.g. nitrogen fixation, phosphate solubilization, production of plant growth hormones, ammonia and siderophore, and indirect mechanisms, e.g. production of antibiotic, hydrogen cyanide to help as biocontrolling agent. Totally, 50 microbes were isolated from soils of vegetable field. Out of 50, 14 strains were selected on the basis of morphological, growth biochemically characters (e.g. gram staining, amylase, cellulase, catalase and citrate test) and plant growth-promoting properties. All strains have ability of ammonia production. Out of 14 strains, IESDV2, IESDV3, IESDV4, IESDV11, IESDV12 and IESD28 were found significant increase in production of IAA, ammonia and phosphate solubilization than others. Strains IESDV3 and IESDV11 showed tolerant at 6 ll/ml concentration of chlorpyrifos which is three-time increase concentration of recommended dose (2 ll/ml). Others strains IESDV12, IESDV13 and IESDV28 were also showed resistance or tolerance at different concentrations of pesticide 2, 4, 6 and 20 ll/ml. These strains also showed plant growth-promoting rhizobacteria activities. Therefore, the main result of this study is to screen and identify that three strains (IESDV3, IESDV11, IESDV12 and IESDV28) can be used as effective pesticide-tolerant plant growth-promoting microbial consortia for vegetable production under sustainable agriculture at eastern Uttar Pradesh.

“…P 50 . Nutrient uptake enhances by inoculated plants may attribute to the production of plant growth regulators by the bacteria at the root interface, which stimulated root development and resulted in better absorption of water and nutrients from the soil (Abbasi et al, 2011). Increasing the bioavailability of P and N in soils with inoculation of PGPR which may lead to increased their uptake and plant growth, was reported by many researchers (Zaidi et al, 2003;Wani et al, 2007).…”

Pirhadi et al.: Impact of soil salinity on diversity and community of sugarcane endophytic plant growth promoting bacteria (Saccharum officinarum L. Abstract. The aim of this study was to isolate and identify culturable bacterial endophytes from sugarcane grown in saline and non-saline soil and assay some plant growth-related traits and evaluate selective isolate potential to improve growth, yield and grain phosphorus uptake of wheat. Endophytic bacteria associated with sugarcane grown in saline and non-saline soil were isolated from roots, stems and leave and tested for their ability to fix nitrogen, indole acetic acid (IAA) production and dissolution of insoluble phosphorus. A total of 55 endophytic bacteria were isolated from leaves, stems, and roots of sugarcane from saline and nonsaline soil. The results revealed a prevalence of Bacillaceae, with Bacillus sp. being the most frequently isolated bacterium. Salinity had the effect on bacterial community structure with the higher diversity of root entophytic bacteria in saline soils. From the isolates, four strains were shown to produce IAA and 19 strains showed the ability to solubilize phosphate, but twelve isolates having the best characteristics tests were identified using 16S rRNA gene sequencing. From the isolates Pseudomonas sp. SugS_49 with more phosphorus dissolution ability selected for evaluation on wheat growth. Application of Pseudomonas sp. SugS_49 caused increased growth, grain yield and phosphorus uptake of wheat.

“…The use of bio-fertilizers with a good management can decrease the leaching loss of nitrate and phosphate from the agricultural land and improve the ground water quality [190]. Also, the use of PGPR with low-fertilizer rate is also an environment friendly step and would be a viable supplementary strategy for further increasing crop yields [71,78,191].…”

Free-living plant growth-promoting rhizobacteria (PGPR) have favourable effect on plant growth, tolerance against stresses and are considered as a promising alternative to inorganic fertilizer for promoting plant growth, yield and quality. PGPR colonize at the plant root, increase germination rates, promote root growth, yield, leaf area, chlorophyll content, nitrogen content, protein content, tolerance to drought, shoot and root weight, and delayed leaf senescence. Several important bacterial characteristics, such as biological nitrogen fixation, solubilization of inorganic phosphate and mineralization of organic phosphate, nutrient uptake, 1-aminocydopropane-1-carboxylic acid (ACC) deaminase activity and production of siderophores and phytohormones, can be assessed as plant growth promotion traits. By efficient use, PGPR is expected to contribute to agronomic efficiency, chiefly by decreasing costs and environmental pollution, by eliminating harmful chemicals. This review discusses various bacteria acting as PGPR, their genetic diversity, screening strategies, working principles, applications for wheat and future aspects in terms of efficiency, mechanisms and the desirable properties. The elucidation of the diverse mechanisms will enable microorganisms developing agriculture further.
