In arid regions, starchy agricultural products such as wheat and rice provide essential carbohydrates, minerals, fibers vitamins. However, drought, desiccation, high salinity, potentially toxic metals hydrocarbon accumulation are among the most notable stresses affecting soil quality cereal production in environments. Certain bacteria, referred to Plant Growth-Promoting Rhizobacteria (PGPR), co...

Aim: To evaluate the effect of co-inoculation with Pseudomonas fluorescens and P. + Azospirillum brasilense on seedling emergence speed, development soybean yield.
 Study Design: Randomized complete block design five treatments eight replications.
 Place Duration Study: Ibiporã, Paraná State, Brazil, during 2020/21 season.
 Methodology: The consisted untreated control (Cont); min...

Azospirillum brasilense, a nitrogen-fixing bacterium found in the rhizosphere of various grass species, and increased the plant growth by growth substances produced by the bacteria like indole acetic acid and indole lactic acid which produced by A. brasilense from tryptophan (Tien et al., 1979; Okon and Vanderleyden, 1997; Bashan et al., 2004). Evaluation of 20 years of data indicated that 60 7...

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...

Given the hypothesis that co-inoculation with plant growth-promoting bacteria (PGPB) enhances beneficial effects of Rhizobium tropici greater mineral nutrition, optimizes biological nitrogen fixation and reduces use fertilizers in bean plants, objective this research was to evaluate synergistic associated Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens their combinations, on...

A multitude of roles is played by microbes in food and agriculture that include nutrient cycling management, organic matter decomposition fermentation. Plant growth promoting rhizobacteria (PGPR), representing microbial groups with ability colonizing plant roots, influence through various indirect direct modes order to promote its and/or protect it from diseases or damage due insect attack. Thu...

Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...
