These fertilizers also make nitrogen available for legume crops by fixing atmospheric nitrogen in the soil and their root nodules. They also enhance the fertility of the soil and improve the yield significantly, without adversely affecting the environment.
Leguminous crops (Fabaceae family) improve soil fertility through nitrogen fixation with the help of rhizobia bacteria, which are found in their root nodules.
The bacteria within root nodules take nitrogen from the air and convert it to a nutrient form that the plant can use for growth and sustenance 6 a process called nitrogen fixation.
The number of root nodules per plant increased significantly (P< 0.05) over non-inoculated plants, with a 61% increase in the nodule count.
Beneficial bacteria in their root nodules pull atmospheric nitrogen into the soil.
Then the plants carefully uprooted and the root nodules were surface sterilized by immersion 4 min in a sodium hypochlorite solution (2%) and washed six times with sterile distilled water.
According to Garbaye and Frey-Klett [1], it is well established that some strains of Rhizobium can exhibit nitrogenase activity when grown in vitro on different media, but such activity has not been reported for Actinomycetes strains isolated from root nodules of N2-fixing nonlegumes [1].
Healthy, unbroken, and pink root nodules from each of the soil samples were randomly selected for isolation of rhizobia.
Production of extracellular polysaccharides by a Rhizobium species from root nodules of the leguminous tree Dalbergia lanceolaria.
Mo is a constituent of nitrogenase, a key enzyme in all [N.sub.2] fixing microorganisms; consequently, nitrogen-fixing plants have a high Mo requirement, particularly in the root nodules (Hille, 1999; Marschner, 2012).
The number of root nodules increased with plant age, being the maximum at the post-flowering stage (90 DAS).
