H.F.Al- MohammediAl- Anbar Provincial Council, Al- Anbar, IraqJournal Article20190916To investigate the response of maize hybrids to plant population and nitrogen fertilization rates. Two field experiments were conducted at the Experimental Farm, Faculty of Agriculture (Saba Basha), Alexandria University during 2018 and 2019 seasons. Factorial experiments (two factors) in randomized complete block design (RCBD). Whereas, the first factor was plant population (50000, 75000, 100000 plant/ha), while, the second factor was nitrogen fertilization rates (216, 288, 360, and 432 kg N/ha). The results revealed that ear length (cm), number of rows/ear, number of grains/row, number of grains/ear, 100-grains weight (g), grain yield (t/ha), straw yield, biological yield (t/ha), harvest index (%) and grain protein content (%) of maize hybrid were, significantly, affected by plant population and nitrogen fertilizer rates, where the highest grain yield was obtained by growing maize plant hybrid 3444 at a population of 75000 plant/ha under the application of 360 kg N/ha under the environmental conditions of Alexandria, Egypt.https://eajbsh.journals.ekb.eg/article_54079_7daf495df003495d3a33526acaf5356f.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

A.El- SheshinyDepartment of Plant Ecology and Rangeland Management, Desert Research Center (DRC), Cairo, EgyptAhmed. H.MohamedDepartment of Plant Ecology and Rangeland Management, Desert Research Center (DRC), Cairo, EgyptJournal Article20191006The northwestern coast of Egypt is one of the most important grazing areas in the country, with a natural rangelands area of about 2.3 million hectares. Rangelands in this area have been facing overgrazing and mismanagement for years, so rehabilitation and restoration approaches are urgently needed for the sustainable development of these rangelands. Hence, this research was conducted at Wadi El-Washka, El- Kaser Region, Northwestern Coast, Marsa Matrouh Governorate, Egypt, in 2017 and 2018 growing seasons to study the effect of compost manure rates on the growth parameters of three forages shrubs species. The experimental design of the experiment was split-plot design with four replications. The main plots included the three shrubs species (<em>Medicago arborea</em>, <em>Periploca angustipholia,</em> and <em>Atriplex nummularia</em>), while compost rates (0, 5, and 10 t/fed) in the subplot. The results concluded that the different shrubs significantly differed under increasing the rate of compost manure. In this respect fertilizing <em>Atriplex nummularia</em> by addition compost at the rate of 10 t/fed as organic manure increased all growth characters including, shrub height of 119.40 and 126.08 cm, number of branches/plants of 11.08 and 11.73 branches, crown coverage of 0.929 and 0.506 m<sup>2</sup> and crown volume of 0.363 and 0.260 m<sup>3</sup> in spring and autumn growing seasons of 2017 and 2018, respectively under study conditions at northwestern coast of Marsa Matrouh Governorate, Egypt. These findings would have management implications for the better use of untraditional water resources for the sustainable development of degraded desert rangelandshttps://eajbsh.journals.ekb.eg/article_61060_c6eb91f617ade0a91dffcc66cdd41e25.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

Most of indigenous knowledge about plants used for the management of malaria is undocumented and the risks of being lost are on the high. The ethnobotanical study documents the different types of medicinal plants used for the treatment of malaria in Kashere and its environs of Akko L.G.A. of Gombe State. Information was collected by interviewing 84 informants, using a semi-structured questionnaire, which included Traditional Medical Practioneers, farmers and other inhabitants who have experience in the management of malaria. Collected plant samples were identified and authenticated at the Federal University of Kashere Herbarium (FUKH). Data was analysed using frequency and percentages. In this study, 81% of the informants are males and 19% are females. A total of 63% of the informants have attended primary school/Islamia education, and 76% of the respondents are aged above 40 years of age. A total of 41 plants species belonging to 28 families were identified. Most plants used in the management of malaria in Kashere community belong to Fabaceae (12%), Rutaceae (7%), Asteraceae (7%) and Malvaceae (7%) plant families. <em>Azadirachta</em> <em>indica</em> A. Juss is with the highest relative frequency of citation (RFC- 0.74) among the plants surveyed. The main method of preparation is decoction and dominant plant parts used in the preparation of remedies were leaves. The diversity of medicinal plants species used and associated indigenous knowledge are of great value to Kashere community and their conservation and preservation is paramount.https://eajbsh.journals.ekb.eg/article_64078_c364f4898a2e70a4910f0b0b0465954a.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

The phytoacaricidal activity of <em>A. maurorum</em> plant extracts was evaluated against <em>Panonychus citri</em>. The aerial part of <em>A. maurorum</em> was extracted by methanol, petroleum ether, and water separately using the soaking and Soxhlet extraction. The rate of female daily deposited eggs varied considerably according to <em>A. maurorum</em> plant extracts and the sublethal concentrations. A few numbers of eggs laid were observed with the methanol extract (0.73 eggs), petroleum ether (2.16 eggs), and aqueous (4.31 eggs) at LC<sub>75</sub>, while the high number observed in the untreated female groups (29.37 eggs) and Selecron insecticide (6.99 eggs). The same pattern was occurred in the hatchability with the tested bio-acaricides compared with Selecron insecticide and untreated ones. Based on sublethal dose LC<sub>25</sub>, LC<sub>50,</sub> and LC<sub>75</sub>, the tested acaricides was significantly reduced the number of hatched eggs, where it reached (30.7, 13, 5.6%), (37.6, 21.6, 15%) and (44.3, 30.8, 23.8%) for methanol, petroleum ether, and aqueous plant extract, respectively compared with untreated groups (91.2%). Concurrently, data showed that methanol extract has a significantly impacted on the reduction of viability (58.16%) and reproductive process while the effect was less with the aqueous plant extracts (46.21%). Gas chromatography/mass spectrometry (GC-MS) analysis identified various bioactive complexes (phenols, tannins, and fatty acids) with insecticidal activity. The peak of compounds was higher in Benzene, (1-butylhebtyl)- undecane, 5-phenyl (8.75 %), Maltol 4H-pyran-4-one,3-hydroxy-2-methyl(2.74%) 9,12,15-Octadecatrienoic acid, linolenic acid (2.45%) in petroleum ether extract and 4H-pyran-4-one,2,3-dihydro-3,5-dihydroxy-6-methyl (3.66%), 2-Furan-carboxaldehyde, 5-(hydroxymethyl) (3.33%), Bis(2-ethylhexyl) phthalatehalic acid, bis(2-ethylhexyl)ester (5.58%) in methanol extract. 2,3-Dimethylpenzene-1,4-dicarbonitrile (20.26%), 4-Fluoroveratrole, fluorobenzene,3,4-methoxy (19.52%) and Hexadecanoic acid (0.87 %). Finally, we concluded that methanol, petroleum ether, and aqueous extracts screened showed phytoacaricidal activity against mite <em>P. citri</em>.https://eajbsh.journals.ekb.eg/article_93239_fe6274d8a23be8bc0d534dd43eb93a9a.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

Ten SSR primer pairs revealed a high percentage of polymorphism (97.4%) among 38 total number of alleles, while 11 SCoT primers produced 48.5% from 171 amplified fragments. SCoTs recorded effective multiplex ratio (EMR) and PIC values of 7.5 and 0.14, respectively, opposing to 3.7 and 0.26 for SSRs, respectively. A similar marker index has thus resulted in both markers. Nei’s gene diversity (h) was generally low for both marker systems indicating homogeneous nature and narrow genetic background for the studied Egyptian date palms, which was also emphasized through their high genetic similarity estimates. The results of UPGMA cluster analysis and PCoA grouped the eleven date palms according to their geographical location and sex. In addition to classical morphological characters, the current study confirmed the importance of using SCoTs as functionally gene-based multi-loci markers besides nuclear SSR loci to assess the genetic variations and cultivar identification among Egyptian date palm genotypeshttps://eajbsh.journals.ekb.eg/article_108312_5370d92358b57e9fc1fd3e704499d218.pdf
