The goal of this study was first to assess the dynamics of the bacterial community during a growing season in three Indian rain-fed wheat fields which differ mainly through their fertilizer management and yield and then to study the effects of PGPR/AMF bio-inoculations on the bacterial community structure and wheat growth. The bacterial community structure of the rhizosphere soil (RS) and the...

Bacterial community associated with the rhizosphere of wheat: interactions with arbuscular mycorrhizal fungi and selection of plant growth promoting rhizobacteria for the increase of wheat growth and soil health in Indian marginal rainfed fields

Thèse de doctorat : Université de Neuchâtel, 2005 ; 1790.

The objective of this thesis was to improve our knowledge on the interactions between wheat, rhizobacteria and arbuscular mycorrhizal fungi (AMF) in the mycorrhizosphere in order to define criteria for the selection of plant growth promoting bacteria (PGPR) strains in view of a PGPR/AMF dual inoculation in Indian wheat fields. First, microcosm systems were set-up to obtain mycorrhizosphere,...
