To evaluate the effect of Azospirillum and mycorrhizal soil fungi on nutrition Jerusalem artichoke crop (Helianthus tuberosus L.), determinations agronomic parameters health status plants were carried out under field conditions. The tests out, at time implantation culture: "seeds" inoculated with A. brasilense native fungi, generating four treatments including control co-inoculation consortium ...

The Pseudomonas fluorescens complex includes Pseudomonas strains that have been taxonomically assigned to more than fifty different species, many of which have been described as plant growth-promoting rhizobacteria (PGPR) with potential applications in biocontrol and biofertilization. So far the phylogeny of this complex has been analyzed according to phenotypic traits, 16S rDNA, MLSA and infer...

Arbuscular Mycorrhizal Fungi (AMF) constitute a group of root obligate biotrophs that exchange mutual benefits with about 80% of plants. They are considered natural biofertilizers, since they provide the host with water, nutrients, and pathogen protection, in exchange for photosynthetic products. Thus, AMF are primary biotic soil components which, when missing or impoverished, can lead to a les...

A field experiment was carried out at Agricultural Researchs and the Experiments Station in Wasit province during 2019-2020 season. This study aimed to investigate effect of three factors, first being biofertilizer levels (without addition , a combination Bacillus megaterium + Glomus mosseae complet G. mosseae, Azotobacter chroococcum, B. Azospirillum brasilense). second factor vermicompost (wi...
