Effect of Using Trichoderma spp. on Turfgrass Quality under Different Levels of Salinity

Lawns achieve environmental, functional, and aesthetical roles in urban environments. The objectives of this research were to assess the effect different salinity levels on Trichoderma isolates study spp. perennial ryegrass under salinity. T. harzianum (ThLem2017-01) atroviride (TaDP2019-01) had a higher mycelium growth rate than (TaDP2019-02) when low. In contrast, isolate at high superior results. Turfgrass seeds that inoculated with maintained radicle length, coleoptile leaf length levels. Increasing level decreased clippings’ fresh weight (FW), dry (DW), shoot root ryegrass. Interestingly, pots treated increased FW DW by 16 114% 24 76%, respectively. Soils CO2 respiration (75%) control. Therefore, using revealed promising results increasing plant biomass as an environmentally friendly alternative factor overcome stress.
