Abstract: A pot trial was conducted at Main Agricultural Research Station, College of Agriculture, UAS, Dharwad during kharif 2013 to study the interaction between Glomus macrocarpum and the best compatible biocontrol agent on growth and yield of chilli (Capsicum annuum L.). In earlier studies carried out at UAS, Dharwad, Glomus macrocarpum and biocontrol agent, Pseudomonas fluorescens or Trichoderma harzianum was studied in green house trial in chilli. In the compatibility study, significantly highest mycorrhizal spore counts and per cent root colonization, dry matter production and uptake of phosphorus were noticed in the chilli crop inoculated with Glomus macrocarpum alone and higher population of biocontrol agents was noticed in single inoculation with Glomus macrocarpum + Pseudomonas fluorescens. The significantly highest mycorrhizal spore counts and per cent root colonization in the rhizosphere soil of chilli crop were observed both at 50 per cent flowering and at harvest in treatment given recommended dose of nitrogen and potassium + 50 per cent phosphorus + Glomus macrocarpum. The significantly highest dehydrogenase, phosphatase activities and population of free living nitrogen fixers in the rhizosphere soil of chilli crop, chlorophyll content in the chilli leaves, plant height, dry matter production, dry chilli yield per plant in gram, dry weight of 100 chilli fruits in gram and dry chilli yield quintals per hectare in the chilli crop, nutrient content colour value and ascorbic acid content in chilli fruits were observed both at 50 per cent flowering and at harvest in treatment given recommended dose of nitrogen and potassium + 50 per cent phosphorus + Glomus macrocarpum + Pseudomonas fluorescens.
