pH effects on nodulation and biological nitrogen fixation in Calopogonium mucunoides
(2016-12-01)
Calopogonium mucunoides Desv. is able to form nodules, root organs in which biological nitrogen fixation takes place, after a symbiotic interaction with soil bacteria known as rhizobia. Such distinct advantage of some ...
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(Springer, 2017-09)
Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ...
Biological nitrogen fixation in soybean in Argentina: relationships with crop, soil, and meteorological factors
(2015-07)
Aims: This study aims to (i) asses the contribution of biological N fixation (%Ndfa) in the soybean production area of Argentina, (ii) build a model for predicting %Ndfa using crop, soil, and meteorological variables, and ...
Metabolic features involved in drought stress tolerance mechanisms in peanut nodules and their contribution to biological nitrogen fixation
(Elsevier Ireland, 2017-10)
Legumes belong to the most important crops worldwide. They increase soil fertility due their ability to establish symbiotic associations with soil microorganisms, known as rhizobia, capable of fixing nitrogen from the ...
Agronomic performance of maize (Zea mays L.) genotypes under Azospirillum brasilense application and mineral fertilization
(Univ Nacional Cuyo, Fac Ciencias Agrarias, 2021-06-01)
Maize has a high nitrogen (N) demand; as a result, more sustainable alternatives are needed to reduce demand for mineral fertilizers. The hypothesis is that the agronomic performance of maize genotypes diverges in their ...
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)
Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ...
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)
A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the
use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ...
Nitrogen rates associated with the inoculation of Azospirillum brasilense and application of Si: Effects on micronutrients and silicon concentration in irrigated corn
(Sciendo, 2018-01-01)
The aim of this study was to analyze whether there are differences between the inoculation with Azospirillum brasilense and the silicon application, thus enabling a higher efficiency of nitrogen fertilization, evaluating ...
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)
Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ...
