Biostimulants are substances and/or microorganisms that applied to plants or the rhizosphere in order enhance natural process improving absorption of nutrients and quality crops as well tolerance abiotic stresses. A new biostimulant was developed from sewage sludge through its fermentation with Bacillus licheniformis a plant growth-promoting bacteria (PGPB). The fermented product includes three...

The garden pea (Pisum sativum L.), like most members of Fabaceae family, is capable forming symbioses with beneficial soil microorganisms such as nodule bacteria (rhizobia), arbuscular mycorrhizal (AM) fungi and plant growth promoting (PGPB). autoregulation nodulation (AON) system known to play an important role in controlling both the number nodules level root colonization by AM via root-to-sh...

Nitrogen is an essential plant nutrient, widely applied as N-fertilizer to improve yield of agriculturally important crops. An interesting alternative to avoid or reduce the use of N-fertilizers could be the exploitation of plant growth-promoting bacteria (PGPB), capable of enhancing growth and yield of many plant species, several of agronomic and ecological significance. PGPB belong to diverse...

Common fertilizers present a low use efficiency caused by nutrient losses (e.g., through leaching, volatilization, adsorption, and precipitation in solution as well microbial reduction immobilization) that create significant limiting factor crop production. Inoculation with Plant Growth-Promoting Bacteria (PGPB) is presented an alternative to increasing fertilizer efficiency. The goal of the st...

Brazil is the second-largest producer and first exporter of beef, with herds mainly raised in extensive pastures, where Megathyrsus maximus occupies over 30 Mha. About 70% pastures are under degradation, using plant growth-promoting bacteria (PGPB) may contribute to reversing this scenario. We investigated effects PGPB on growth six cultivars M. maximus—Tanzania-1, Massai, BRS Zuri, Mombaça, Ta...

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 ...

Canola (Brassica napus L. var. oleracea) is the third most common oil-producing crop worldwide after palm and soybean. cultivation requires use of chemical fertilizers, but amount required can be reduced by applying plant growth-promoting bacteria (PGPB). Among PGPB, endophytic have certain advantages as biofertilizers, canola rarely been studied. In this work, we identified a collection bacter...

Nitrogen (N) fertilization is a crucial agricultural practice for boosting production traits in vegetables. However, N synthetic fertilizers—commonly adopted by farmers—have several counterproductive effects on the environment and humans. The research was performed to assess combined influence of plant growth promoting bacteria (PGPB) (Azospirillum brasilense DSM 1690, A. 2298 Pseudomonas sp. 2...

Selenium (Se) is essential for the basic functions of life, but low daily intake Se urges us to find reliable ways increase food content. Plant-growth-promoting bacteria (PGPB) have shown potential in enhancing plant growth and accumulation. In this study, soils collected from a tailing were used isolate Se-tolerant PGPB. The results showed that total three strains identified. Strain LWS1, belo...
