Evaluation of Effect of Organic Fertilizer’s Treatments and Soil Compaction on the Qualitative Traits of Sport Lawn in Different Seasons
Keywords:Appearance quality, Chlorophyll, Media, Roller, Traffic
Natural structure of lawn brings about the sensitivity of it to climate conditions and imposed destructive forces during its use. In this study, the effect of several types of organic fertilizers including leaf mold (LM), rice husk (RH), livestock manure, spent mushroom compost (SMC), a mixture of LM, RH and livestock manure (mixture 1), a mixture of LM, RH and SMC (mixture 2) with the ratio of 1:1:1 and control (no fertilizer) along with several levels of compaction including roller weighted of 36, 56 and 76 kilograms were studied on the change qualitative traits of sport lawn in different seasons. An experiment was conducted at the strip plot design in three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-2009. According to the results, the chlorophyll rate in the fall was higher than winter and spring. With the comparison of the cover rate, density and height, it was observed that in different seasons, the highest and lowest rate of these attributes was related to spring and summer respectively.
