Azospirillum brasilense and Saccharomyces cerevisiae as Alternative for Decrease the Effect of Salinity Stress in Tomato (Lycopersicon esculentum) Growth

The salinity stress is one of the most relevant abiotic stresses that affects agricultural production. present study was performed to improvement salt tolerance tomato plants which known for their susceptibility stress. aimed assess what extent strain Azospirillum brasilense (N040) and Saccharomyces cerevisiae improve treated with different concentration. inoculant A. previously adapted survive up 7% NaCl in basal media. A greenhouse experiment conducted evaluate effect this inoculation on growth parameter such as: plant height, root length, fresh dry weight, fruits chlorophyll content, proline total soluble sugar under condition. results revealed co-inoculation significantly increased level (8.63 mg/g FW) (120 leaves condition comparing non-inoculated (2.3 FW 70 FW, respectively). Plants co-inoculated S. showed highest significant (p < 0.01) increase fruit yield (1166.6 g/plant), high (115 cm) roots length (52.6) compared whit un-inoculated control (42 g/pant, 43.3 cm 29.6 cm, In contrast, Na+ ion content decreased stressed cerevisiae. Finally, dual benefits provided by both can provide a major way yields saline soils.
