Abstract :

Pot experiments were conducted under greenhouse conditions to investigate the effect of three arbuscular mycorrhizal (AM) fungi (Glomus fasciculatum, Glomus mossae and Acaulospora leavis) individually and its interaction with rhizobium in a mixture, on the growth and mineral nutrition of Winged bean (Psophocarpus tetragonolobus). Inoculation of AM fungi along with rhizobium in different combinations of single and triple inoculation gave different results in growth parameters like plant height, dry weight of shoot and root, per cent root colonization, nodule number, spore number, P and N uptake. In conclusion, it was found that Glomus fasciculatum was found to be efficient AM fungi for winged bean and inoculation of all the three AM fungi and rhizobium resulted in highest growth parameters.
