| Abstract: | A nursery experiment was conducted to assess the effect of bioinoculants (Glomus aggregatum, Bacillus polymixa, Azospirillum brasilense) on seedling growth promotion of bamboo (Dendrocalamus strictus (Roxb.) Nees.) in two soil types (alfisol, vertisol) with or without fertilizer application. Bamboo seedlings were grown
in the presence or absence of bioinoculants either individually or in all combinations for 180 days in field soil under tropical
nursery conditions. Shoot, rhizome and root length, dry masses, nutrient concentrations and arbuscular mycorrhizal (AM) colonized
root lengths were determined at harvest. Under the experimental condition tested combined inoculation of AM fungi, PSB and
A. brasilense resulted in maximum growth response both under fertilized and unfertilized conditions in both soil types. Fertilizer application
enhanced the efficiencies of N, P and K uptake, whereas reduced their usage efficiencies. Though soil type did not affect
microbial inoculation response, fertilizer application significantly affected plant response to microbial inoculation. |
