Proso millet (Panicum miliaceum L.) was grown with inoculation of four indigenous AM fungal species in presence of different levels of mine spoil under green house conditions. The growth parameters such as biomass production, grain yield, per cent root infection and number of viable AM fungal spores in the rhizosphere of the mycorrhizal proso millet grown with 25% mine spoil were higher over th...
