Abstract
During winter season of 2015 a pots experiment was carried out at private farm on two soils of Egypt (clay and sandy) varied in their physo and chemical properties to study the individual and combined effects of salinity level of irrigation water either of un-or magnetized irrigation water and biofertilization on nodulation efficiency and growth of common bean plants (Phaseolus vulgaris L Nebrasca c.v). The used salinity levels were 300, 700 and 1900 mg/l. The layout of the experiment was split-split block design in three replicates of each soil.                                             
The obtained data show a significant decrease on nodules number formed on the roots of common bean plants. On the other hand, application of magnetic technique and biofertilizer resulted in a significant increases of nodules number. These findings may be cleared from the calculated relative change values "RC" of the studied three factors on nodulation number. With the same treatment nodules number formed on the roots of common bean plants grown on clay soil was higher than that formed on the plants grown in sandy soil. Similar effect for the studied three factors was found on both fresh and dry weights (g/pot) of common bean plants (shoots) at growth period of 45 day: These results concluded that, applying magnetic technique and biofertilizer application decreased the hazard effect of water salinity and increased nodulation efficiency and plant growth.
