A pot experiment was carried out during 2009 -2010 to study the impact of microbial inoculants on plant height of Blue pine (Pinus wallichiana A.B. Jackson) and Himalayan cypress (Cupressus torulosa Don) under nursery conditions. The experiment was laid in Completely Randomized Design with three replications which comprised forty-two treatment combinations of seven inoculants (Azotobacter sp., Azospirillum sp., Pseudomonas fluorescens, Bacillus subtilis, Pisolithus tinctorius, Laccaria laccata and control). The growth character viz., plant height at various intervals responded significantly to all the microbial inoculants. Maximum plant height was recorded in Himalayan cypress (38.72 cm) as compared to Blue pine seedlings (24.78 cm). Among microbial inoculants the two ectomycorrhizae viz., Pisolithus__ampersandsignnbsp;tinctorius and Laccaria laccata gave best results than rest of the inoculants. It was followed by Azotobacter sp., Azospirillum sp., Pseudomonas fluorescens and Bacillus subtillis. Thus the two treatments viz., Pisolithus tinctorius and Laccaria laccata proved to be the best for the studied parameter viz., plant height of both the species.
