Sugar palm (Arenga pinnata) and Pindo palm (Butia capitata (Mart.), have great economic values and they are excellent palm trees for landscapes. Meanwhile, palm growth and quality are greatly affected by nutritional deficiencies. Different nitrogen sources may be preferred for use with different plant species. Since there is not enough information about fertilization treatments for most of ornamental palms, especially at early growth stages under local conditions in Egypt. Therefore, the objectives of this study are to identify the most appropriate type of nitrogen sources to fertilize ornamental palms of Arenga pinnata and Butia capitate for improving vegetative growth and successful establishment stage in transplanted from containers. Three different sources of nitrogen as ammonium sulfate at 5 g/pot, potassium nitrate at 3g/pot, and urea at 2 g/pot, were applied. The results revealed that vegetative growth parameters and chemical analysis contents of the studied palms, varied among the three treatments of nitrogen sources, the highest value of plant height, number of leaves, fresh and dry weights of leaves and roots achieved with potassium nitrate at 3g/pot. The highest values of chemical content, increased progressively by potassium nitrate and ammonium sulfate as compared with urea. It can be recommended to use potassium nitrate at 3g/pot or ammonium sulfate at 5 g/pot to improve the vegetative growth characteristics of the two ornamental palm plants.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132925050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Root knot nematodes interrupt the physiology of the plant and able to cause economic importance great losses in production and quality of sugarbeet crop. Chemical nematicides are usually preferred for their effective control; the problems associated with nematicides application turned the workers vision to focus new alternative agents for nematode management programs. In this study, High throughput microcrystalline cellulose decorated silver nanoparticles (Ag-NPs) by different concentrations were evaluated as a nematicidal substance in outdoors pots experiment. The chosen tested concentrations were 20, 30, 40, 50, and 60 ppm/ml of Ag-NPs with four replicates/ each concentration along with two methods of application [one time application (AT1) and application two times (AT2)], applied to sugarbeet pots infested with Meloidogyne incognita. Applying Ag-NPs directly to infested sugarbeet pots achieved significant suppression at p ≤ 0.05 of root-knot nematode, M. incognita in terms of reducing numbers in soil, reproductive factor, and knot disease severity%. Efficacy % that related to untreated pots and relative efficacy% that proportionated to pots treated with Ethoprop 10% G get higher potential as of Ag-NPs of concentrations get higher. Time of application AT2 enhanced the efficacy of Ag-NPs at low concentration (under 50 ppm/ml) and occasionally above 50 ppm/ml. Effects of different Ag-NPs concentrations and times of application on yield components i.e. Root yield plant(g), Top yield plant(g) and sugar yield plant(g) of infested sugarbeet plant with root-knot nematode, M. incognita, were related to degree of Ag-NPs concentration to suppress nematodes activity. Different concentrations of Ag-NPs increased yield components i.e. Root yield plant(g), Top yield plant(g) and sugar yield plant(g) even at low concentration (20 ppm/ml) in comparison with control treatment (0.0 ppm/ml). The same trend for quality as sucrose, total soluble solids (T.S.S) and purity percentages of sugarbeet infested with root-knot nematode, Meloidogyne incognita in pots experiment. Avoidable loss percentage in roots and sugar yields plant(g) as an economic expression responded positively to different levels of Ag-NPs concentrations and to time of application AT2 in low concentration ˂50 ppm/ml.

Marjoram is also a common spicy medicinal herb. It's also used in food all over the world to add flavor. The mineral content, vitamin A content and fatty acid profile of the marjoram herb were estimated in this study. The sensory properties, quality properties, mineral content, fatty acid composition and physical properties of snacks containing marjoram powder (2.5, 5, and 7.5 %) were also assessed fatty acids (PUFA), followed by monounsaturated fatty acids (MUFA) and saturated fatty acids (SFAs). The data revealed that the marjoram herb has mineral content. The vitamin A content of the marjoram herb, on the other hand, was 1570.36 mg/kg. Marjoram herb also contains a high amount of unsaturated fatty acids (74.35%), especially Linolenic acid (44.9 %). The results, on the other hand, showed that there were no major variations in all sensory properties between the marjoram-fortified snacks and the control snacks at p ≤ 0.05. The addition of marjoram powder to snacks improved the snack's consistency. The most prevalent fatty acids in marjoram-fortified snacks were polyunsaturated. On the other hand, Elaidic acid isomers in snacks containing marjoram powder decreased as marjoram powder levels increased. As different levels of marjoram powder were increased, all minerals present in snacks increased. When the amount of marjoram powder added was increased from 0 to 7.5 %, the water absorption index of snack samples increased and the expansion ratio decreased. Finally, adding marjoram powder to the snack formulation improved the micronutrient content, sensory quality, Tran's fatty acid content and nutritional quality of the snacks.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115277069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
