Effect of diazotrophic bacteria and thiamine on growth and regrowth of millet

COLLOQUIUM AGRARIAE, 2019
The objective of this study was to evaluate the effect of the isolated and joint use of Azospirillum brasilense inoculation and the application of thiamine, on seed or leaf, on the development of millet in two cycles. A randomized complete block design was used in five replicates.

Selection of diazotrophic bacteria isolated from wastewater treatment plant sludge at a poultry slaughterhouse for their effect on maize plants [PDF]

, 2018
The economic and environmental costs of nitrogen fertilization have intensified the search for technologies that reduce mineral fertilization, for example atmospheric nitrogen-fixing (diazotrophic) bacteria inoculation. In this context, the present study

Spatial and Temporal Distribution of Two Diazotrophic Bacteria in the Chesapeake Bay [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT The aim of this study was to initiate autecological studies on uncultivated natural populations of diazotrophic bacteria by examining the distribution of specific diazotrophs in the Chesapeake Bay. By use of quantitative PCR, the abundance of two nifH sequences (907h22 and 912h4) was quantified in

Does Slight Soil Acidification Negatively Affect Diazotrophic Bacterial Community in Paddy Field? A Regional-Scale Study

Ecosystem Health and Sustainability
Diazotrophic bacteria are eco-friendly alternatives for reducing chemical N fertilizer use. Yet, their responses to soil acidification from excessive fertilization in paddy ecosystems remain unclear. To elucidate this issue, we compared the structure and

Iron Homeostasis in Azotobacter vinelandii

Biology, 2023
Iron is an essential nutrient for all life forms. Specialized mechanisms exist in bacteria to ensure iron uptake and its delivery to key enzymes within the cell, while preventing toxicity.

OPTIMIZATION OF BIOFERTILIZERS ENRICHED IN N BY DIAZOTROPHIC BACTERIA

European Journal of Sustainable Development, 2017
Free-living diazotrophic bacteria can enrich organic biofertilizer in nutrients to application in sustainable agriculture. The objective of the study was to select diazotrophic bacteria isolated from different soils, evaluated by analyses of nitrogenase activity.

Diazotrophic bacteria in the growth of micropropagated ornamental pineapple

Revista Colombiana de Ciencias Hortícolas, 2019
Ornamental pineapple is a hardy plant with significant landscaping value. Tissue culture of plants is viable for producing plants with a high phytosanitary quality. However, one of the difficulties with this cultivar is the acclimatization process, which is slow and can cause losses.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Potassium solubilization in phonolite rock by diazotrophic bacteria

Comunicata Scientiae, 2017
Some strains of nitrogen fixing bacteria, besides fixing the N2, can produce phytohormones, control pathogens, act in solubilization of minerals containing phosphorus (P) and potassium (K), contributing to plant growth. However, the solubilization of minerals containing K has been little exploited.
