Preconditioning of Pseudomonas fluorescens at 40, 35 and 30°C temperatures for 48 and 72 hrs. were found increased plant growth promoting efficacy. Influence of different concentrations on plant growth promoting efficacy were also studied by using P. fluorescens as seed treatment. The dilutions starting from 10⁻¹ to 10⁻⁸ significantly increased the growth of rice seedling over control. The bacterial inoculum applied under fumigated conditions as seed dressing or soil application significantly increased the growth of rice seedling over non fumigated conditions. P. fluorescens growth promoting performance was recorded superior with FYM amended soil over unamended soil.
