This study was conducted during the period 2014-2016 in the nursery College of
Agriculture, University of Tishreen, this study aimed to calculate the percentage of
germination of the seeds of Laurus nobilis and Pinus pinea using different proportio
ns of
olive cake with a mixture Arboretum, and study some of the planter resulting properties as
well as some physical and chemical characteristics of agricultural mixture that used. were
analyzed using spss statistical program
The mixing nursery soil (sand, soil 1: 1) with olive cake rates (25,50,75,100)% .
assessment: germination percentage, wet and dry weight of shoot and root grouped,
volumetric weight, moisture middle and chemical characteristics. , For germination
percentage it has increased every germination of seeds of laurel and pine fruiting increase
the proportion of bagasse in the agricultural center in general ratio, and on the contrary has
increased wet weight of shoots with decreasing proportion of olive cake in both types
studied. For the physical properties there was a decrease in the volumetric weight of the
agricultural community to increase the proportion of the studied olive cake, as soil
moisture ratio increased to increase the proportion of bagasse. Rich agricultural circles
used container Regarding chemical properties have been observed on the olive cake metal
elements (iron, magnesium and copper), The salinity and acidity remained within normal
limits, so the study has demonstrated the validity of the use of olive cake as a medium for
planting in whole or in part agricultural mixtures used in nurseries.
This research was carried during the period of (2010-2013) to study the possibility of benefiting from the raw seaweeds residuse accumulated on the Syrian beach in obtaining an alternative substrates instead of the traditional one for using in
nurseries, especially forestry, and thus reducing the peat moss importation and saving the currency, at the same time salvation the environment from the organic plant waste and and improve the seashores appearance .
