dc.description.abstractThe present investigation entitled “Evaluation of bio – inoculants on rooting behaviour and growth of air layering of guava, lemon and antagonistic effect of bio control agents against soil borne pathogen (Sclerotiumrolfsii and Rhizoctonia solani)”was carried out in the Plant Pathology section, Barrister Thakur Chhedilal college of Agriculture & Research Station (BTCCARS), Bilaspur (C.G.) with aim to study the plant growth potential and antagonistic effect of different indigenous bio-inoculants (Azospirillum, Pseudomonas fluorescens and Trichoderma harzianum, T. viride) on air layering of guava and lemon plants andagainst soil borne plant pathogens i.e. Sclerotium rolfsii and Rhizoctonia solani. Results indicate that number of primary roots, number of secondary roots, length of primary roots and secondary roots, number of new leaves emergesin different bio-inoculants applied alone or in combinationsi.e. Azospirillum+ P. fluorescens, Azospirillum+ T.viride, Azospirillum+ T. harzianum, T. viride+ P. fluorescens and T. harzianum + P. fluorescens were significantly higher as compared to uninoculated control, further it was also recorded that all the treatments were effective in increasing survival percent of guava and lemon plants transplanted under greenhouse conditions in polythene bags as compared to untreated control.Findings also suggest that among different treatments, combination of Azospirillum and P. fluorescens was found to be the significantly superior with respect to development of primary and secondary roots as well as survival of treated guava and lemon plants followed by Azospirillum, P. fluorescens, T. viride and combination of Azospirillum & T. viride, T.harziamun and P. fluorescens were significantly effective in arresting mycelia growth of S.rolfsii and R. solani under dual culture technique as compare to control. However T.harzianum (T3) and P. fluroscences (Pf10) were highly effective amongst all indigenous strains show effective growth over S. rolfsii and R. solani. Findings also suggest that other indigenous strains i.e. T. harzianum (T28) and P. fluorescens (Pf2) also showed a good antagonistic activity over control.en_US
