Elham M. Aref( 2011). Response Of Faba Bean Plants Grown On Saline Soil To Azolla, Cyanobacteria And Yeast Extracts Applied As Foliar BiofertilizersEgypt. J. Biotechnol. Vol. 39, October
Abstract: Two field experiments were conducted at the experimental farm of Al- Areesh Res. Station during two successive winter seasons to study the response of faba bean (Vicia faba L. cv. Giza) to inoculation with Azolla, cyanobacteria and yeast individually or mixed with urea under salinity of water and soil.Using Azolla, cyanobacteria and yeast extract as foliar spraying led to increase significantly faba bean yield components in comparison with control. In addition, the application of T8 gave positive correlation with grains yield. Furthermore, cyanobacteria, Azolla and yeast extract led to increase the soil available N P K. All the applied biofertilizers reduced pH and that encounters the salt stress leading to decrease the soil EC degree., consequently increased soil biological activity in terms of increasing counts of the soil total bacteria, total cyanobacteria, rhizobium as well as, CO2 evolution, dehydrogenase activity and nitrogenase activity. This increase of the biological activity increased the soil fertility that in turn is reflected positively on the faba bean yield production.
