Multifarious microbial biostimulants promote growth in Arachis hypogaea L.

Plant Growth Promoting Rhizobacteria (PGPR), a microbial biostimulant has been widely studied to stimulate plant growth through induction of natural biological processes. However, lack successful validation under open field remains barrier mark their standard in agriculture. Therefore, the aim research was highlight potential PGPR biostimulants via vitro studies and subsequently demonstrate planta evaluation oilseed crop, Arachis hypogaea L. (Groundnut) pot trials. The two rhizobacterial strain identified as Pseudomonas fluorescens Bacillus subtilis by 16s rRNA gene sequence analysis. Both strains were functionally screened for promoting traits. Pot trials conducted where seeds inoculated with harvested at 30 90 days. Biostimulant treatments applied single co-inoculation groundnut factors, biochemical parameters, yield, seed quality analyzed. study inferred that consortium significantly ( p < 0.05) showed highest growth, photosynthetic pigments, nodulation status, leghaemoglobin content, yield attributes, also biofortification nutrients crop both conditions than un-inoculated control. This supports idea application trial facilitate its implementation feasible agricultural product synthetic fertilizers thereby influencing sustainable stable production.
