| dc.description.abstract | The present investigation was undertaken to evaluate the microbial and organic formulations for growth promotion and biocontrol activities in baby corn (Zea mays L.) under greenhouse and field condition in Department of Agricultural Microbiology, UAS, GKVK, Bengaluru. To identify the best combinations of microbial and organic formulations to enhance plant growth, nutrient supply and biocontrol activities. Among the biocontrol agents tested Trichoderma harzianum showed maximum per cent inhibition against selected pathogens and jeevamrutha organic liquid showed maximum per cent inhibition against respective pathogens. Among all entomopathogens Beauveria bassiana and panchagavya organic liquid showed highest pathogenic effect on Helicoverpa armigera and Chilo partellus. Biocontrol efficiency, seedling vigour index and mortality per cent were tested in seedling tray experiment using selected microorganisms under green house condition. Higher biocontrol efficiency and seedling vigour index was observed in plants treated with Pathogen + Gluconacetobacter diazotrophicus + Bacillus megaterium + Piriformospora indica + Pseudomonas fluorescens + Bacillus subtilis +Trichoderma harzianum on six pathogens of baby corn and higher mortality per cent was found in larvae infested plants sprayed with Beauveria bassiana + Photorhabdus luminescence + Bacillus thuringiensis on two pests of baby corn. Multiple combination of Gluconacetobacter diazotrophicus + Bacillus megaterium + Piriformospora indica + Pseudomonas fluorescens + Bacillus subtilis +Trichoderma harzianum showed positive influence on growth of baby corn in pot culture experiment under green house condition and significantly increased plant growth, chlorophyll and nutrient content, plant biomass, yield and quality parameters and established better under field condition with less pest and disease incidence | en_US |
