Legumes include soybean, alfalfa, clover, pea, peanut, mesquite, mimosa, and acacia (Figure 7); with the help of symbiotic rhizobia in their root nodules
, most legumes can grow in poor soils without addition of nitrogen-containing fertilizers.

For sterilization first nodes were placed in alcohol for 30 seconds and then in 1% sodium hypochlorite for 5 minutes at the end were rinsed several times with distilled water , 1 to 2 large root nodules
of each sample were selected and placed in the ordinary test tubes containing 1 ml of sterile distilled water and were crushed by the pestle, Then 100 ml of sterile nodes extract were transferred by pipette to YMA medium and were spread in surface, then cultured plates were placed for 48 h in a growth chamber.
