A comparative study was conducted to analyse the effect of arbuscular mycorrhizas (AMF, Glomus mosseae, using 15 g of mixed inoculum placed just below 5 cm in the pots) and addition of phosphorus (P, at 2 g, applied at 30 days after planting) on the growth parameters of B. juncea under greenhouse conditions. In general, due to AMF association, the survival of the saplings was very high compared to saplings grown with added P and under control conditions. The growth parameters such as height of saplings, number of leaves per sapling, fresh and dry weights of leaves and shoots per sapling increased due to the influence of AMF. The moisture content and major essential nutrients (N, P and K) were also found mere in the leaves of AMF-associated saplings. The percentage of root colonization due to AMF inoculum was higher (46.36%) compared to uninoculated saplings (19.58%). The growth response of B. juncea saplings to the treatment of AMF inoculation was significantly superior to that of treatment of P addition and control.
