Abstract
This study was conducted to evaluate the influence of native plant
growth promoting (PGP) potential of bacterial isolates rhizosphere, rhizoplane
and root nodules of velvet bean (Mucuna pruriens L.), a medicinal legume
valued for its therapeutic and agricultural applications. While chemical
elicitors, radiation and heavy metal rhizobia were extensively studied on the
enhancement of L-DOPA content, native microbes associated with velvet bean
remain largely unexplored. 3 bacterial isolates, namely Bradyrhizobium sp.
(NYRL1), Sporosarcina newyorkensis (SPB1) and Sporosarcina
psychrophila (NPB2) including rhizobial and non-rhizobial strains, were
obtained through standard microbiological techniques. Screening for PGP
activities demonstrated capabilities such as phosphorus and potassium
solubilization, siderophore and ammonia production and nitrogen fixation.
Notably, the combination of 3 isolates exhibited the potential for enhancing
plant growth, seed yield and metabolite (L-DOPA) content. This study highlights
the importance of native microbes associated with velvet bean in promoting
plant growth. The findings highlight the role of microbial isolates as
potential candidates for biofertilizer development.
