Some cross-inoculation groups and Rhizobium-Legume associations are shown in table 18.1. Although the cross-inoculation classes are not solely considered for the description of the nodulating performance of many root nodule organisms. Non-Symbiotic N 2-Fixing Bacteria: The non-symbiotic nitrogen fixing bacteria do not require a host plant. read more

Symbiotic bacteria is the one which forms association with either plant , animal or fungus in which bacteria as well as the host , both are benefited. example - Rhizobium bacteria forms association with the root nodules of higher plants , plant provide shelter to the bacteria and bacteria helps in nitrogen fixation. 2. read more
