Abstract
One of the most important factors in lawn establishment is the culture bed. In the present work, weevaluated the effect of some culture beds (1-leaf mold (LM), 2-rice husk (RH), 3-manure, 4-spentmushroom compost (SMC), 5-mixture of LM, RH and SMC (M 1), 6-mixture of LM, RH and M (M 2),with the ratio ...

One of the most important factors in lawn establishment is the culture bed. In the present work, weevaluated the effect of some culture beds (1-leaf mold (LM), 2-rice husk (RH), 3-manure, 4-spentmushroom compost (SMC), 5-mixture of LM, RH and SMC (M 1), 6-mixture of LM, RH and M (M 2),with the ratio of 1:1:1 for both mixtures, along with 7-control treatment in three compactness levels (rollwith 36, 56 and 76 kg weights) on some growth factors of sport lawn during spring. Therefore, anexperiment carried out during 2008-9 in the research farm of Gorgan University of Agricultural Scienceand Natural Resources in strip plots design with three replications. According to obtained results, theinteractions of fertilizer and compactness treatments for some of the measured traits were significant. Thehighest and the lowest chlorophyll content and plant height in all three compactness levels were observedin M2 and control treatments, respectively. Furthermore, in all three compactness levels, the highest drymatter devoted to control treatment and the lowest one was observed in M2 and manure treatment. In caseof lawn coverage rate, density and greenness, the interaction of fertilizer and compactness treatments wasinsignificant and SMC and M2 showed the highest coverage rate and greenness respectively. Inconclusion, organic materials have to be considered as one of the important factors as a result of theirstructural effect on soil physicochemical and biological features.
