Seedlings of 30 days old plants were inoculated (thrice with interval of one month) with two fungal cultures (Aspergillus and Penicillium sp.) and two bacterial strains (BA and BT) with and without NPK and organic manure. Data recorded on no. of leaves, branches and shoot height exhibited the growth enhancing effect of fungal inoculation especially Penicillium sp. Plants inoculated with Aspergillus sp. produced more no. branches comparatively. Individual inoculation of Penicillium sp. and Bacterial strain BT has shown increase in shoot height. The Relative growth rate and leaf area ratio revealed the growth enhancing impact of bioinoculatnts supplemented with fertilizer and/or organic manure. Over all, microbial inoculations were found to be useful in enhancing growth of seedlings in nursery conditions. Rising of nursery of plants with such bioinoculants along with supplementation of fertilizer and organic manure will certainly be helpful in establishment of seedlings in field conditions.
