Sugarcane pre-sprouted seedlings produced with beneficial bacteria and arbuscular mycorrhizal fungi

The demand for the increased productivity of sugarcane crops has required changes in its production chain, such as use pre-sprouted seedlings (PSS) into chain. In this system, inoculation beneficial microorganisms, plant growth-promoting bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF), can improve seedling development. objective was to evaluate effect PGPB AMF on PSS system. Experiments were carried out greenhouse using a commercial substrate with different levels fertilization biomass nutritional status. strains are able produce indole acetic acid amplify nifH gene. coinoculation IAC-BeCa-095 (Glomus macrocarpum Glomus etunicatum) improved shoot (25%) fertilized substrate. IAC-BeCa-088 (Burkholderia caribensis), IAC-RBca5 (Pseudomonas sp.) IAC-RBca10 (Bacillus without by up 35%. Coinoculation strain (Kosakonia radicincitans) root 27 75%, respectively, conventionally substrate, demonstrating synergistic these microorganism consortia. microorganisms may be viable practice sugarcane. Moreover, study is first demonstrate endophytic (K. or rhizobacteria Pseudomonas sp. B. caribensis, inoculum growth nutrition.
