To compare the effect of the substrate on the cultivation of ornamental plants, Ficus benjamina cv. star light was chosen as a model plant. Nine treatments from 8 types of substrates with 6 replications were investigated in this study. Data analysis with SPSS software in (P≤0.05) showed the effect of different month were significant on stem diameter, height, leaf number and total length of new leaves. Also application of different substrates showed the effect of substrate wasn’t significant on stem diameter and plant height, while it was significant on number of new leaf, number of new lateral shoot and total length of new leaf. The interaction between the substrates and measuring time was significant on plant height, number of new leaf and total length of new leaf, but it wasn’t significant on increasing rate of stem diameter. According to the result of this study, substrate n containing [1/3 (3 perlite+1 sand) + 1/3 (1 leaf-mold+ 1 rice hull+ 1 cocopeat) + 1/3 (2 mushroom compost+ 1 forest trees compost+ 1 rotted manure)] was the best substrate as for the most number of new leaf, number of new lateral shoots and total length of new leaf, also it was in suitable situation in height characteristic. Also in different measured month, the value of plant growth was increased with enhancement in air temperature in spring and summer seasons; insofar as the most increasing in plant height and number of new leaf were observed on July. So it is better that the plants growing should be delayed to warm seasons.

Abstract
In current study, seven organic fertilizers including; Leaf Mold (LM), Rice Husk (RH), Manure, Spent Mushroom Compost (SMC), mixture of LM, RH and SMC (M 1), mixture of LM, RH and Manure (M 2) with the ratio of 1:1:1 and control (no fertilizer) along with some levels of soil compactness comprising roller ...

In current study, seven organic fertilizers including; Leaf Mold (LM), Rice Husk (RH), Manure, Spent Mushroom Compost (SMC), mixture of LM, RH and SMC (M 1), mixture of LM, RH and Manure (M 2) with the ratio of 1:1:1 and control (no fertilizer) along with some levels of soil compactness comprising roller weights of 36, 56, 76 kilogram were used. Treatments were applied in a strip plot design with three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during fall 2008-2009. Effects of these treatments were investigated on chlorophyll content of lawn, amount of density and cover rate, growth height and percent of plant dry matter in fall season. According to results, SMC and RH treatments in first compactness, manure and M2 treatments in second compactness and manure treatment in third compactness showed the maximum chlorophyll content. The most and the least amount of nitrogen in each three compactness levels were observed in manure and control treatments, respectively. The highest density was related to manure treatment and the lowest one was related to LM treatment. In each three compactness, maximum and minimum height was observed in manure and control treatments, respectively. This project results will be used for lawn management in relation to the use of organic fertilizer and compactness rate of planting bed in Gorgan city conditions.
