Abstract

The experiment was conducted to evaluate growth promotion of transplanted rice by fungal and bacterial bioagents effective against brown leaf spot of rice. Bioagent formulations (T. viride, T. harzianum, Pseudomonas fluorescens and Bacillus subtilis) were applied as seed treatment and foliar spray and compared with untreated check. All bioagent formulations were significantly effective in increasing number of tillers per hill, root length, fresh and dry root weight, fresh and dry shoot weight and grain yield over check. Present study revealed that potential fungal and bacterial bioagents effective against brown leaf spot disease of rice, exhibited plant growth promoting activities and resulted, 21.69 to 28.77 reducing the disease severity and 34.42 to 40.99 increase in grain yield over untreated check, even if there is no disease.
