Chickpea establishes symbiotic association with Mesorhizobium to fulfill its nitrogen (N) requirement. Integrating chickpea rhizosphere with potential native mesorhizobia and other plant growth promoting microorganisms can contribute multiple benefits to plants. The present investigation was undertaken to study interactions among Piriformospora indica (PI) with potential plant growth promoting rhizobacteria (PGPR) viz. Pseudomonas argentinensis (LPGPR1), Pseudomonas sp. (LPGPR2) along with national check Pseudomons sp. (LK884) and Mesorhizobium cicer (LGR33, MR) to examine the synergistic effect of consortium for improving growth, symbiotic efficiency, nutrient acquisition and yield in two chickpea (Cicer arietinum L.) varieties viz. desi PBG1 and kabuli BG1053. In-vitro, seed germination with consortium MR+PI+LPGPR1 was the best compatible treatment followed by MR + PI + LK884 and MR + PI + LPGPR2. Significant improvement in the growth, symbiotic parameters and grain yield was observed with MR +PI+ LPGPR1 and MR+PI+LK884 treatments. Significantly high chlorophyll and leghaemoglobin content was recorded with MR+PI+LPGPR1 (1.57 and 1.64 mg g ). Data revealed significant increase in total nitrogen (N) and phosphorus (P) content of shoot with MR+PI+LPGPR1 by 1.2 and 1.5 fold, respectively over MR alone treatment. On the basis of overall mean, MR+PI+ LPGPR1 significantly improved the yield by 8.2 % over Mesorhizobium alone application. It seems from foregoing study that tripartite combination of different microorganisms can be explored as biofertilizer for improvement in chickpea productivity.

“…These products include Plant Growth Promoting Rhizobacteria (PGPR) and chitin by-product, such as chitosan. Antoun & Prevost (2005) affirmed that soil microorganisms having beneficial activities on plant growth and health represent an interesting and effective alternative to conventional agriculture. Plant Growth Promoting Rhizobacteria is a group of bacteria capable to actively colonize the plants root system and improve their growth and yield (Wu et al, 2005).…”

KEYWORDS ABSTRACTThe aim of this study was to assess the combined effects of the three plant growth promoting Rhizobacteria (Azospirillum lipoferum, Pseudomonas fluorescens and Pseudomonas putida) and a biostimulating molecule (chitosan) on plant growth parameters and seeds yield of maize in southern Benin. This study was conducted in reddish ferrous soil with fisher block experimental design. Maize seeds were soaked into chitosan solution for 12 hours and introduced into a seed hole with bacterial suspension. Experimental maize plants were fertilized by half or complete dose of NitrogenPhosphorus-Potassium (NPK) and Urea. Result of the study revealed that the combination of P. fluorescens along with chitosan and half dose of NPK-Urea increased maize height, circumference and seeds yield of 10.18%, 22.05% and 44.10% respectively. Furthermore, the produced biomass increased 71.43% compared to the control in the combination of P. fluorescens, chitosan and complete dose of NPK-Urea. Results of study suggesting that PGPR and chitosan can be used as an effective biological fertilizer combination for increasing maize production under field conditions.

“…They enhance plant growth through numerous mechanisms including the protection of roots against infection by pathogens, fixed nitrogen, soluble phosphate, production of phytohormones and siderophores (Glick et al, 1999;Naik et al, 2008), lowering of the ethylene level within the plant or by the enhanced production of stimulatory compounds, such as plant growth regulators (Antoun and Prévost, 2005). Among plant growth regulators, indole-3-acetic acid (IAA) is the most common natural auxin found in plants and its positive effect on root growth and morphology is believed to increase the access to more nutrients in the soil (Vessey, 2003), maintaining apical dominance, regulating phototropic and gravitropic behavior in plants (Palme et al, 1991), and stimulating the density and length of root hairs through producing phytohormone within the root zone (Gyamfi et al, 2004;Turnbull, 2001).…”
