The cost of inorganic fertilizers is increasing enormously, it has become impractical to apply such costly inputs for crops and which makes soil unfertile. Use of biofertilizeris practically advantageous, in these biofertilizers beneficial organisms are helpful in phosphate solubilization, nitrogen fixation etc. They are known to improve growth and yield of crop. The roots of chilli normally form a symbiotic association with AMF. In mycorrhizal association, AMF has been shown to be beneficial to the host plant by increasing nutrient uptake particularly N, P, K. Certain plant growth promoting rhizomicro organisms has been reported to enhance the activity of AM fungi and consequently plant growth. Hence, an experiment was conducted during the year 2013 under greenhouse condition by using Byadagi dabbi variety of chilli and plant growth promoting Pseudomonas and AM fungi at University of Agricultural Sciences, Dharwad, Karnataka. The enhanced activity by rhizosphere microbial population such as phosphate solubilizers and nitrogen fixers in rhizosphere soil was observed. The fluorescent pseudomonads and AM fungi are known to produce certain plant metabolites, plant growth promoting substances, vitamins, etc. Their synergistic interactions is said to be responsible for the increased activity of micro flora and enzyme activity in rhizosphere.
