Abstract: Catharanthus roseus (L.) G. Don widely known medicinal herb, belongs to Apocynaceae family has been cultivated for its wide range of therapeutic values. Arbuscular mycorrhizae (AM) are helpful symbionts for growth of the plant and its development, offering a possible substitute for high input agricultural technology employed for production of environmentally hazardous fertilizers. Therefore, the present investigation was focused on to analyze the effect of AM fungi (Acaulospora laevis and Glomus mosseae) along with Pseudomonas fluorescens, alone and in combinations, on different growth parameters of Catharanthus roseus in a pot experiment with autoclaved sterilized soil under polyhouse condition. AM inoculum and P. fluorescens showed significant increase in different growth parameters after 120 days of inoculation. Among all treatments, consortium of G. mosseae, A. laevis plus P. fluorescens was most effective for increased shoot height, root length, leaf area, shoot and root biomass, percent root colonization and AM spore number. Moreover, chlorophyll content, phosphorous and phosphatase activities were found to be maximum when AM fungi and P. fluorescens were applied in consortium.
