Nitrogen supply associated with rhizobacteria in the first productive cycle of Marandu grass
(2021-01-01)
The rhizobacteria of genus Azospirillum and Bacillus are effective at fixing atmospheric nitrogen, promote plant growth and can largely contribute to beneficial recovery from degraded pastures. This study aimed to evaluate ...
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(Wiley, 2016-10)
A main goal of biological nitrogen fixation (BNF) research has been to expand the nitrogenfixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ...
How do phosphorus, potassium and sulphur affect plant growth and biological nitrogen fixation in crop and pasture legumes? A meta-analysis
(Elsevier Science, 2014-02-01)
Worldwide, legumes are grown on approximately 250 M ha and fix about 90 Tg of N2 per year. Plants involved in biological nitrogen fixation (BNF) are particularly sensitive to deficiencies of phosphorus (P), potassium (K) ...
Supplementary reinoculation in topdressing of Rhizobium tropici in common bean crop: effects on nodulation, morphology, and grain yield
(2021-01-01)
Besides nitrogen fertilization (N), other processes constitute sources capable of supplying large amounts of N to plants, such as biological nitrogen fixation. In general, the inoculation technique exclusively in the seed, ...
Wheat yield in the Cerrado as affected by nitrogen fertilization and inoculation with Azospirillum brasilense
(Empresa Brasil Pesq Agropec, 2017-09-01)
The objective of this work was to evaluate the effect of inoculation with Azospirillum brasilense, associated with N rates and sources, in soil of the Cerrado (Brazilian savanna), on the grain yield of irrigated wheat ...
The elusive quantification of nitrogen fixation in xeric shrubs: The case of Adesmia volckmanni, a Patagonian leguminous shrub
(Academic Press Ltd - Elsevier Science Ltd, 2014-12)
The comparison of 15N natural abundance (δ15N) between fixing and non-fixing reference species, is the most feasible method for nitrogen fixation studies in xeric shrubs. However, it assumes that both species use the same ...
