FOLIAR FERTILIZATION WITH COMMERCIAL LIQUID FERTILIZER FOR IMPROVING GROWTH AND QUALITY OF SEASHORE PASPALUM TURF

An investigation was conducted under the open field condition at the Experimental Farm of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to study the effect of some commercial liquid fertilizers; super blue-green (SBG) at the rates of 1 and 3 ml/l, Kalsin-A (K-A) at the rate of 1 ml/l and the combinations between the two levels of SBG and that of K-A on growth, density and chemical composition of seashore paspalum (Paspalum vaginatum Swartz) planted in 40-cm-diameter plastic pots filled with about 6 kg of sand and clay mixture (1:1, by volume) when applied as a foliar spray, 5 times with one month interval. The control plants were sprayed with tap water only. The obtained results indicated that all single and combined treatments used in the study markedly improved all vegetative growth traits of the fertilized plants with various significant differences compared to control plants in the two seasons. Among the sole treatments, SBG at 3 ml/l treatment was the superior, whereas the same fertilizer and K-A one at 1 ml/l for each were the inferior. On the other hand, combined treatments induced a more improvement in all vegetative growth parameters than the individual ones, but the prevalence in both seasons was for SBG at 3 ml/l + K-A at 1 ml/l combined one, which gave the highest records at all. A similar trend was also observed as well regarding the leaf content of chlorophyll a, b, carotenoids, N, P, K, Ca and total soluble sugars except for 1 ml/l KA treatment which gave the highest content of Ca among the sole treatments, and the increment in total soluble sugars content was attained by the individual fertilization treatments as was not significant relative to control in both seasons. In addition, the total indole content was significantly increased in response to the different treatments used in this study to reach the maximum by the two combined treatments. The opposite was the right concerning the content of total phenols. Accordingly, it can be advised to spray the herb of seashore paspalum turf with a combination of super blue-green liquid fertilizer at 3 m/l plus Kalsin-A at 1 ml/l, five times with one month interval to obtain the best growth, coverage and colour

The School Environment in Egypt. A Situation Analysis of Public Preparatory Schools [Arabic]

Very little research exists in Egypt on contemporary education outcomes and their relationship to an array of education inputs. Also, few datasets are available on the acquisition and retention of basic skills from education. This research aims at filling that gap in our knowledge by drawing a profile of the situation of public preparatory schools, investigating the distinct dimensions of the environment in these schools, and examining the links among these dimensions and specific education outcomes. As noted in this report, this study focuses on the preparatory stage of the general education system. Students in this stage comprise one-quarter of all pre-university students in Egypt

Social Change and Parent Adolescent Dynamics in Egypt

This volume represents revised versions of a collection of papers presented at Cairo Papers Ninth Annual Symposium on \u27\u27The New Arab Family,\u27\u27 held in May 2000. Marriage, divorce, and related topics were center stage, particularly in the demographic papers. Another focus was to combine two very different approaches to the study of the family -- on the one hand demographic, and on the other broadly sociological or anthropological, or as some would say, psychodynamic, that is to say focusing on dyadic or multi-member networks of relationships within the family. Some of these papers in turn focused on \u27\u27agency,\u27\u27 the ways in which individual action fit into cultural and social frames. The research covers most of the Arab world, though with a focus on Egypt. In addition to general papers relying on demographic data from different parts of the Arab world, the volume includes case studies from Tunisia, Lebanon, and Saudi Arabia.https://fount.aucegypt.edu/faculty_book_chapters/2112/thumbnail.jp

Transitions to Adulthood: A National Survey of Adolescents in Egypt [1st edition, Arabic]

Egypt holds a unique place among developing countries due to its longstanding commitment to gather information on the numbers and well-being of its population. But until now, there has never been a systematic effort to gather data on the group of young Egyptians poised between childhood and adulthood—its adolescents. Today, Egypt has the largest cohort of adolescents in its history, more than 13 million boys and girls between the ages of 10 and 19 according to its 1996 census. Their experiences during the transition to adulthood will profoundly affect how the nation makes its transition into the next century. This research report contains the early findings of a nationally representative survey of 9,000 adolescents aged 10-19 and their parents, conducted in 1997, and aims to provide a comprehensive picture of the contemporary situation of Egypt’s young people. The report attempts to achieve a fuller understanding of the major developmental “tasks” each adolescent undertakes as he or she moves toward the roles and responsibilities of adulthood, as well as household perspectives on the services and institutions available in Egypt to support those transitions

Antiviral and Antioxidant Potential of Fungal Endophytes of Egyptian Medicinal Plants

This study aimed to explore the antioxidant potential and antiviral activity of endophytic fungi which were isolated from healthy living tissues of medicinal plants. Endophytic strains (29 different taxa) were isolated from 18 Egyptian medicinal plants collected from Saint Katherine Protectorate, Egypt. The fungal endophytes were identified based on morphological characters. All isolates were identified as ascomycetes, except two Zygomycetes strains (Absidia corymbifera and Mucor fuscus). Isolated endophytes were cultivated on potato dextrose media. The fungal metabolites were extracted by ethyl acetate and examined for their biological activities. Among 99 total extracts, only Chaetomium globosum, which was isolated from Adiantum capillus, showed a promising DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity (99% at 100 µg/mL). Fifteen extracts prohibited the reproduction of HSV-2 virus. On the other hand, the reproduction of VSV-virus was inhibited by sixteen endophytic extracts. The promising anti-(HSV-2 and VSV) extract of endophytic Pleospora tarda strain; that was originally isolated from the medicinal plant Ephedra aphylla, showed viral inhibitory activity of 40.7% and 15.2%, respectively. Two compounds, for which antiviral activates could be attributed, were isolated and identified as alternariol and alternariol-(9)-methyl ether using different NMR techniques from P. tarda extract. For the first time, we report here the ability of the endophytic fungus P. tarda to produce alternariol and alternariol-(9)-methyl ether. The results indicate that the endophytic fungi from medicinal plants are promising sources of bioactive compounds
