ABSTRACT
Inoculation of P. mullesua plantlets with AMF at various levels of organic manure was found enhancing the biomass, shoot length, P and N content. It signifies that organic amendment supported increase in plant biomass and mycorrhizal fungal infection with P. mullesua. AM fungal species Glomus versiforme was found most effective for increasing the plant growth in all the three levels of FYM. The phosphatase enzyme activity in all the FYM levels was found higher which indicate that the application of FYM increased phosphatase activity of AMF. The correlation coefficient between plant biomass and phosphatase activity of AMF was highly significant (p>0.001) under FYM level I and III. Concentration of P and N in seedlings was found higher than that of non-mycorrhizal one. Mycorrhizal inoculants particularly G. versiforme, G. aggregatum, G. claroidium were better than other AMF in enhanching the growth of plantlets at all the three levels of FYM.
