Nowadays, many investigations are done on plants waste that can be used as bio soil amendments. The use of biological fertilizers instead of chemical ones has been considered widely because of environmental issues importance. Cultivation beds have some influence on both stability and quality of sod. The current study was done to assess the impact of 5 soil compounds on two steps of bermudagrass sod production (cultivation in cartonplast and establishment) as a completely randomized design with three replicates. The soil compounds were clay, sand and spent mushroom compost in different compositions. Our results showed that at the time of lawn cultivation in cartonplast, the highest clipping fresh and dry weight and the best plant density were related to clay + spent mushroom compost (1:1) (v.v). We also found that the best color quality was related to clay + spent mushroom compost (1:1) (v.v), sand + spent mushroom compost (1:1) (v.v), clay + sand + spent mushroom compost (1:1:1) (v.v.v) bed while the lowest height of shoots was related to clay + sand (1:1) (v.v). In the second phase of the experiments, the highest clipping fresh and dry weight was related to clay + spent mushroom compost (1:1) (v.v), sand + spent mushroom compost (1:1) (v.v) bed. The highest shoots height was related to those beds too. The lowest establishment time was related to sand + spent mushroom compost (1:1) (v.v) bed. Finally, our results showed that spent mushroom compost can be used as a useful organic fertilizer which improves soil physical and chemical characteristics.
