A greenhouse study was conducted to determine the influence of microbial amendments on the effective utilization of residual P sources for the growth of pigeonpea. Inoculation of soil with Glomus aggregatum increased the per cent mycorrhizal colonization in roots of pigeonpea in soils with residual P sources of soluble P (SOP), Mussorrie Rock Phosphate (MRP), Udaipur Rock Phosphate (URP), Tricalcium Phosphate (TCP) and North Carolina Rock Phosphate (NCRP) irrespective of presence of phosphorus dissolving fungus, Aspergillus awamori. VAMF inoculation increased the mean number of trifoliate leaves and height of plants grown in soil with residual P sources of MRP, URP, NCRP and NOP. Significant increase in total plant biomass due to mycorrhizal inoculation wa observed l. The plants grown in soil with residual P source of SOP produced highest shoot dry weight, root dry weight and total biomass. over all mycorrhizal inoculation could utilize residual P sources more effectively in the presence or absence of phosphorus dissolving fungal partner.
