abstract

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits such as shoot nitrogen and phosphorus content, shoot height, shoot dry and wet weight, total root length, root fresh and dry weight and root dry weight were evaluated. the results showed that the application of vermicompost and humic acid had a positive significant effect on shoot dry weight, sod root dry weight, total dry weight of roots, fresh weight of root, shoot nitrogen and phosphorous content compared to control. the vermicompost in 15% v/v and humic acid in 150 g/m2 treatments had the most positive effect on measured traits and increased nitrogen (25.4 percent), phosphorous (39.6 percent) content, shoot dry weight (49.7 percent), root weight (83.3 percent), total root dry weight (215 percent) and sod root dry weight (204 percent). in this research application of vermicompost and humic acid increased uptake of nitrogen and phosphorus and it increased the sod quality.
