Moench were grown without combined nitrogen in a growth chamber.

Two phases of early vegetative growth were identified by their different responses to combined nitrogen.

Although overall growth increased with irradiance, the growth responses to combined nitrogen addition were similar at both light levels.

All five strains produced hemoglobin when grown on media without (–N) or with (+N) combined nitrogen.

Combined nitrogen (N) has adverse effects on virtually all stages of the Rhizobium–legume symbiosis.

The growth of cultures provided with combined nitrogen was dependent on oxygen availability, and strict anaerobic conditions did not support growth.

Polymer-rich cells fixed atmospheric nitrogen in the absence of exogenous carbon and combined nitrogen.

Most of the world's supply of combined nitrogen is biologically fixed at normal temperatures and standard atmospheric pressure by soil microorganisms.

The RE of plants grown without combined nitrogen declined during the vegetative phase of growth and increased after flowering.

Cyanobacteria use many sources of combined nitrogen, like nitrate, nitrite, ammonium, urea, or some amino acids.

Combined nitrogen and boron application significantly improved the 3-year mean height and volume increment over that obtained with nitrogen alone.

Over the next 2 weeks, combined nitrogen increased the relative growth rates to a lesser extent, primarily through an increased partitioning of assimilates to shoot development.

Together, their combined nitrogen additions to the soil of their habitats may account for 10-60% of annual nitrogen input in those ecosystems.

These results suggest the possibility of enhancing N2 fixation in peas through selection of rhizobia with maximum effectiveness at low levels of combined nitrogen.

Exogenously supplied combined nitrogen increased seedling growth but did not improve nodule development or endophyte morphogenesis in the ineffective nodules.

Fuel NOx It results from the oxidation of organically combined nitrogen in the fuel in aromatic compounds such as amine and pyridine.

In general, cyanobacteria are able to utilize a variety of inorganic and organic sources of combined nitrogen, like nitrate, nitrite, ammonium, urea, or some amino acids.
