Special Issue Information

Dear Colleagues,

By the end of the 1970s, the term plant growth-promoting rhizobacteria (PGPR) was coined to designate rhizosphere-isolated pseudomonads that, following seed inoculation, rapidly colonized plant roots and increased crop yield. The concept was adopted and developed by several researchers and, more recently, it was extended to any bacteria (PGPB) or any microorganism (PGPM) exhibiting plant growth-promoting (PGP) traits, such as nitrogen fixation, phosphate and potassium solubilization, the production of siderophores, indolic compounds, and 1-aminocyclopropane-1-carboxylate (ACC) deaminase or that lessen or prevent the deleterious effects of one phytopathogenic organism, and that is effective in benefiting plants. In addition to the formulation of conventional inoculants, studies with PGPM are evolving to the construction of synthetic communities, an approach that can be linked to metagenomic analysis, in order to identify the keystone taxa of soil microbiome and interfere in it to improve plant growth. This Special Issue welcomes all types of articles focusing on PGPM, including original research and reviews.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Field research was conducted in Poland in 2019–2021 to determine the effect of microbial products and living mulches on grain yield and grain yield structure elements as well as the biological index of soil fertility (BIF) in spring barley grown in organic agriculture. Two factors were examined: I. microbial products: control (no treatment with microbial products), inoculation with phosphorus-releasing bacteria (Bacillus megaterium var. phosphaticum, Arthrobacter agilis), and co-inoculation (simultaneous inoculation) with phosphorus-releasing bacteria (Bacillus megaterium var. phosphaticum, Arthrobacter agilis) and nitrogen-fixing bacteria (Azospirillum lipoferum Br17, Azotobacter chroococcum); II. living mulch: control (no living mulch—spring barley grown in a pure stand), red clover, red clover and Italian ryegrass, and Italian ryegrass. The study results demonstrated that the highest grain yield at 4.5 t ha−1 with superior structure was produced by spring barley following co-inoculation with phosphorus-releasing bacteria (Bacillus megaterium var. phosphaticum, Arthrobacter agilis) and nitrogen-fixing bacteria (Azospirillum lipoferum Br17, Azotobacter chroococcum). The highest value of the biological index of soil fertility (BIF II) determined at the flowering stage was obtained in plots with spring barley cultivated with the living mulch of red clover mixed with Italian ryegrass or red clover following inoculation with phosphorus-releasing bacteria and nitrogen-fixing bacteria 6.9 and 5.7, respectively.

Plants do not grow in isolation; they interact with diverse microorganisms in their habitat. The development of techniques to identify and quantify the microbial diversity associated with plants contributes to our understanding of the complexity of environmental influences to which plants are exposed. Identifying interactions which are beneficial to plants can enable us to promote healthy growth with the minimal application of agrochemicals. Beneficial plant–microbial interactions assist plants in acquiring inaccessible nutrients to promote plant growth and help them to cope with various stresses and pathogens. An increased knowledge of plant–microbial diversity can be applied to meet the growing demand for biofertilizers for use in organic agriculture. This review highlights the beneficial effects of soil–microbiota and biofertilizers on improving plant health and crop yields. We propose that a multi–omics approach is appropriate to evaluate viability in the context of sustainable agriculture. Full article
