The present study was conducted to assess the role of two mycorrhizal fungi (Glomus fasciculatum and Piriformospora indica) and two bacterial (Azotobacter and Pseudomonas) biofertilizers on growth and micronutrient uptake in bamboo seedlings. Various parameters such as shoot height, number of sprouts, root dry mass, per cent root colonization and micronutrient content were studied. The application of P. indica resulted in maximum enhancement in shoot height and number of sprouts. However, the dual inoculation of Pseudomonas+P. indica resulted in maximum per cent increase in shoot height over control plants, nine months after inoculation. The inoculation ofP. indica also resulted in increased uptake of micronutrients such as zinc, copper, manganese and iron. Dual inoculation of both bacterial cultures of Azotobacter and Pseudomonas also enhanced uptake of zinc, manganese and copper, but to a lesser extent.
