Assessing the efficacy of climate resilient microbial inoculants for enhanced phytochemical production from Indian licorice (Abrus precatorius L.)

Effect of species diversity levels and microbial consortium on biomass production, net economic gain, and fertility of marginal land

“…Application of the PGPM resulted in significant changes in plant biomass generation and economic yield as well as improving soil properties compared with uninoculated controls. The applied consortium of PGPM is already known to enhance plant growth, raise secondary metabolites in Indian licorice, and improved soil fertility of marginal soil (R. Mishra et al, 2021). Our study gained support from some others who have also used a consortium/ PGPM ‐ finding it aids seed germination, plant growth, and productivity better than single inoculants (Jayashree & Jagadeesh, 2017; Kour et al, 2020; Rajasekhar et al, 2016; Rana et al, 2020; Rastegari et al, 2020; Schoebitz et al, 2016).…”

“…The consortium was grown in modified broth media [NB+ PDB (1:1) + 0.5% beef extract] at 30 ± 2°C and incubated for 48–72 hr. Freshly prepared culture of the consortium was mixed into sterilized cow dung and jaggery (carrier material in 9:1 ratio and C–N ratio – 30:1) and kept for 15 days incubation at room temperature with 15% moisture content following the procedure of R. Mishra et al (2021).…”

“…Plant growth‐promoting microbes (PGPM) have been applied to enhance the productivity and yield of such crops; this is an ecological intervention for restoring the soil carbon pool of agroecosystems and increasing crop productivity, as well as soil fertility (Gouda et al, 2018; N. Khan et al, 2019; Tahami et al, 2017). A consortium of PGPM has been found to favour plant growth and improve secondary metabolites better than individual microbial strains (Jayashree & Jagadeesh, 2017; Kalaiyararsi & Victoria, 2016; R. Mishra et al, 2021). Similarly, in Our present study, a consortium of four PGPM (Bacteria: Bacillus pseudomycoides and Bacillus firmus ; Fungi: Aspergillus luchuensis and Aspergillus tamarii ) was used and its efficacy was assessed (on growth and productivity of the cropping system as well as at improving soil fertility of marginal land).…”
