Abstract

     Developing strategies to tackle water stress in lawns in arid climate regions is significantly important. In such conditions, using growing media amendments as well as native plants can relieve drought stress in different growing stages of the plants. This study was carried out to investigate the effects of some types of soil amendments on the emergence and early seedling establishment of tall fescue (Festuca arundinecea Schreb ‘GazBorkhar ecotype’) under water stress conditions. The experiment was performed in a factorial trial based on a completely randomized design with three replications. The first factor, water stress, was applied based on field capacity (FC) at three levels (80% FC (control), 60% FC and 40% FC). The second factor, growing media amendments, was applied at nine levels of municipal solid waste (MSW), vermicompost (5% and 10% w/w), Stockosorb® (1% and 3% w/w) or zeolite superabsorbent (4% and 8% w/w) which were mixed with loam soil, and the loam soil was used as a control treatment. Theresults showed that using an irrigation system at 60% FC during seed emergence and early seedling growth did not reduce the quality of the turf grass, and also, in many cases, led to a higher quality lawn compared to the control, leading to water saving in turf grass management. Using MSW and manure vermicompost as soil amendments could maintain soil moisture and water supplement for the improvement of morphological, physiological and visual quality of this ecotype of Festuca arundinacea Schreb.
