In the present study, 217 rhizobacterial isolates were obtained from six different tea estates of Assam, India and subjected to preliminary in vitro plant growth promotion (PGP) screening for indole acetic acid (IAA) production, phosphate solubilization, siderophore production and ammonia production. Fifty isolates showed all the PGP traits and five isolates did not exhibit any PGP traits. Thes...

the effect of arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria, with the ability to produce acc deaminase enzyme, on water relationships and agronomic indices of sunflower (helianthus annuus l.) cultivars was investigated. the soil used was of an ec equal to 7.6 ds m-1. a greenhouse factorial experiment on the basis of a completely randomized block design with three levels ...

environmental problems associated with the excessive use of chemical fertilizers and abiotic stresses due to soil pollution by heavy metals have encouraged use of biological fertilizers in modern agriculture. in order to protect environment and reduce the tension caused by heavy metals, it is essential to use biofertilizer in crop production. to assess the effects of biofertilizers on yield and...

The tomato leafminer, Tuta absoluta (Meyrick) is a devastating pest associated with tomato. In this study, effects of tomato plants treated with vermicompost (20, 40, and 60%), humic fertilizer (2, 4 and 6 g/kg soil) and plant growth promoting rhizobacteria (Pseudomonas fluorescens and Bacillus subtilis) were investigated on the life table parameters of T. absoluta in a growth chamber at 25 ± 2...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

the present study was conducted to determine the plant growth-promoting activities of bradyrhizobium sp. (vigna) strain mrm6 grown in the presence and absence of the selected herbicides, quizalafop-p-ethyl and clodinafop. the herbicide tolerant bradyrhizobium sp. (vigna) strain mrm6 was further tested for bioremediation and plant growth promoting potential using greengram as a test crop, grown ...

in order to investigate the effect of plant growth promoting rhizobacteria (pgpr) along with zinc (zn) and manganese (mn), foliar spraying on the morphological parameters of basil (ocimum basilicum l.) an experiment was conducted in factorial based on a randomized complete block design with three replications in 2011. treatments were the pgpr inoculation with azotobacter and azospirillum (azb+a...
