rhizobial

Several genera of rhizobial bacteria live symbiotically with leguminous plants and are by far the most important fixers of nitrogen on land, whereas cyanobacteria dominate the process in freshwaters as well as in the ocean.

To improve mineral nutrition of nitrogen fixing trees on acid soils it is important to ensure that the trees are infected with effective rhizobial and mycorrhizal symbionts.

· If the seeds will be stored for a considerable time, they should be treated with a fungicide, but one that will not damage rhizobial or mychorrhizal symbionts.

Now, however, several international laboratories and private companies produce rhizobial and mycorrhizal inoculants for experimental and commercial purposes.

Occurrence and rhizobial selection for legume trees adapted to acid soils.

Chapter 8 1996

The rhizobial bacteria form nodules on the roots of leguminous trees and other plants: nitrogen fixation occurs inside these nodules through a symbiotic process that involves both bacteria and plant.

Chapter 5 1996

Nematode infection may reduce rhizobial colonization and, hence, nitrogen fixation.

Roskoski et al., (1982) measured rhizobial activity in situ in a

This would represent nitrogen both from the soil and from rhizobial fixation.

The experiment was conducted to determine the effects of rhizobial inoculation and nitrogen applied at 0, 30, 60 and 90 kg ha-1 on growth and performance of intercropped maize and mungbean.
