moreA pot trial was executed on certain faba bean varieties (Giza Blanka, Giza 461, 634, 674 and 717) were grown in sandy soil at the green house of National Research Centre, for investigating to what extent biofertilization with a soil yeast Rhodotorula glutinis may lower the deleterious effect of salinity stress. Increasing salinity level was accompanied by decreasing dry weight particularly with the high concentration (6000 ppm). Inoculation with Rhodotorula augmented plant dry weight in all tested varieties in comparison with the uninoculated ones with increasing percents ranged from 17.78 to 8.18 being the highest with variety Giza 461 and the lowest with Giza 717. Each of protein level, soluble carbohydrate, potassium content and catalase activity in plant leaves of various varieties greatly affected by increasing salinity level. Inclusion of Rhodotorula glutinis to salinity treatments mitigated their adverse effects. On the other hand, each of sodium, proline and hydrogen peroxide contents in plant leaves was increased with increasing salinity levels. Bio-treatment of Rhodotorula glutinis resulted in reducing values of the previous parameters for all tested faba bean varieties either the salt tolerant or the sensitive ones
