Abstract: An attempt was made to apply putative fungal and bacterial bio-control agents possessing multifarious plant growth promoting (PGP) traits in view of enhancing growth parameters, grain as well as fodder yield of vital but underestimated crop viz., finger millet (Eleusine coracana L.). The experiment comprises a total of seven treatments including untreated control. A total of four bio-control isolates were investigated viz., Trichoderma asperellum Th-14, Trichoderma harzianum Th-21, Pseudomonas fluorescens Psf-121 and Pseudomonas fluorescens Psf-4. These bioagents were used through seed bio-priming technique along with value added FYM. The remaining treatments of the present study were as seed hydro-priming along with FYM, only FYM and untreated control. The treatment T1 (Seed bio-priming with Trichoderma asperellum Th-14+ FYM pre-colonized by Th-14) was found significantly superior over all the treatments with respect to all the studied traits related to growth, yield and yield contributing attributes at the same time reducing foot rot disease caused by Sclerotium rolfsii followed by the treatment T4 (Seed bio-priming with Pseudomonas fluorescens Psf-4 + FYM pre-colonized by Psf-4) and T2 (Seed bio-priming with Trichoderma harzianum Th-21+ FYM pre-colonized by Th-21) which were statistically at par. The study revealed that the bio-control strains showed significant potential when used along with FYM. However, the treatment T1 proved to be most effective in improving the growth, yield and yield contributing attributes and also helped in suppressing incidence of foot rot disease in finger millet under present materials and environmental conditions.
