study of tobacco west compost and organic fertilizer on some physical and chemical properties of clay soil

The effect of clay soil treatment with two levels of tobacco west compost and organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three replicates of each treatment on some physical properties (Aggregate size distribution, main weight diameter, bulk density and porosity) and chemical properties (Organic carbon, humic and volvic acid and humification index for big and small soil aggregates was studied. The results showed that tobacco west compost and organic fertilizer were effective in increment of soil content of organic carbon, which reached (20 and 26%) for organic fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate soil physical properties, where The main weight diameter, stable aggregate rate and soil porosity were increased. Whereas, bulk density decreased significantly in both treatments compared to the control. Compost treatment affect soil physical properties more than organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to the control. Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile, volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and 3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates. Humification index values were less than 2 in macro aggregates, while it was bigger than 2 in small aggregates.

Contribtion study in biochemical composition of jellyfish (Rhopilema nomadica, Pelagia noctiluca and Aequorea forskalea) In the coastal water of Lattakia port

Due to the lack informations on Biochemical of jellyfish in the Syrian waters, the aim of this paper is determining the nutritional value and organic content for each of the species Rhopilemanomadica, Pelagianoctiluca and Aequorea forskalea, and compared the biochemical composition of the three types , so the comparison showed clear differences in the content of organic material, the sugar were the most concentrated in the three species and lipid comes in second class, and then followed by the protein content and organic carbon.A.forskalea was the most containing sugar and R.nomadica the most lipids content, and P.noctiluca were the most protein content.R.nomadic was the highest content in organic carbon, R.nomadica and P.noctiluca were convergent contents of organic phosphorus, while the least contain of organic nitrogenwas in A.forskalea.

Study of the effect of using bumblebees and organic carbon in improving fruit set and yield of tomato under green house

The experiment was carried out at Jableh region during 2012-2013 in two green houses to study the effects of using the bumble bees and organic carbon to improve flower set and yield of tomato hybrid Dalloula . The experiment included three treatments : natural pollination (control) ,flowers pollination by organic carbon, and flowers pollination by bumble bees . The first and second treatments were applied in the first green house , and the third treatment was applied in the second green house . Results showed that the bumble bees treatment produced significantly the highest percentage of flower set and yield than the other treatments . Flower set of tomato over 10 clusters was 89.8% , 83.7% , 39.2% for bumble bees treatment, organic carbon treatment, and control , respectively. The highest yield (22 kg/m2)was obtained from bumble bees treatment . Flowers pollinated by bumble bees gave fruits that looked better in shape , size and color ,and with higher weights . In the bumble bee pollinated flowers , the quality of fruits was superior for vitamin C , sugar and acidity .
