Exploration of Saurashtra Soil PGPR Strain and its Attributes in Crop Productivity by Pot Plant Study

Abstract

The impact of rhizobacteria with PGPR trait in current agriculture practices is expanding its horizons at large in research and practices. The urge of improvised crop productivity and disease management for economically important myriad crops like cereal plant, and angiosperms, monocots, dicots need to address in versatile manner with integrated approach. The need of a potent trait of PGPR rhizobacteria and its real time application in field trials is more challenging and to address the same, the present research study has been carried out. The present study encompassing the one phase of the project is to isolate the Rhizobial trait from the soil sample followed by the screening of the potent traits. Total 4 potent rhizobacterial isolates have been screened among 41 bacterial isolates from different sites of the Saurashtra region. Qualitative and quantitative characterization of growth promotion factors such as HCN production, ammonia production, IAA production, and siderophore production of the isolates (KS2, KC8, KC9, and KC11 showed) were carried out. Among 21 isolates the 4 isolates KS2, KC8, KC9, and KC11showed the highest growth parameter production and have been stated as PGPR traits. Employing One way ANOVA a statistical design, the shoot and root length effect has been studied in detail with the individual strains KS2, KC8, KC9, and KC11 along with control. The study is quite encouraging with improved root length 10.54±0.33 cm and shoot length 27.20 ± 0.8 cm respectively. The future prospect of this study can be highlighted in long-term with further analysis on consortial development and its field trial applications.
