In this effort, the phytotoxicity and stimulatory effects of graphite and silica Nanoparticles (NPs) on seed germination, yield characteristics, chemical conformation and root anatomical characteristics of (Pimpinella anisum L.) cv. anise were studied. Seeds were soaked in six concentrations of the two NPs (0, 20, 40, 60, 80 and 100 ppm) for 24 hrs to investigate germination under laboratory conditions. The same concentrations were used soaking and foliar application in the open field. The results displayed that silica NPs improved seed germination traits as comparing graphite NPs. Silica NPs at 20 and 40 ppm, showed the highest germination parameters for anise seeds. The increasing in germination % reached to 21.88%. Meanwhile, 80ppm silica NPs enhanced the seeds yield fed.-1 by 64.8%, Number of umbels by 50%, root diameter plant-1, epidermis thickness and cortex thickness. Silica NPs (60ppm) increased biochemical characteristic. Otherwise, graphite NPs (80ppm) enhanced volatile oil% and root vascular cylinder thickness. In general, there was a considerable response by anise seeds to graphite and silica nanosized presenting the possibility of a new methodology to overcome problems with seed germination and increasing the oil percent in some plant species, mostly medicinal plants.}, keywords = {Graphite NPs,Silica NPs,anise,Seeds germination,yield,essential oil,Root anatomical characteristics}, url = {https://jsas.journals.ekb.eg/article_5218.html}, eprint = {https://jsas.journals.ekb.eg/article_5218_2799406c0823713f8bdf7ffe470d20de.pdf} } @article { author = {Ambar, Khairy and Eid, Yahya and Azoz, Abobakr and Elgebaly, Mahmoud}, title = {Effect of Stocking Density and Dietary Phytobiotics on Growth Performance in Rabbit During Summer Season}, journal = {Journal of Sustainable Agricultural Sciences}, volume = {44}, number = {1}, pages = {13-20}, year = {2018}, publisher = {The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)}, issn = {2536-9571}, eissn = {2536-958X}, doi = {10.21608/jsas.2018.2449.1049}, abstract = {The aim of this study was to investigate the effects of different stocking density and dietary phytobiotic on growth performance, body temperature, carcass traits and economic efficiency of growing APRI- line rabbits under heat stress condition. One hundred and eight APRI- line rabbits were divided and assigned randomly into nine groups of 5 weeks of age (620 ± 6g), each group with 12 rabbits. The experimental design was factorial 3 x 3, whereas three stocking densities (2, 4 and 6 rabbit/cage) and three levels of dietary phytobiotic (0, 0.5 and 1% lycopene). Results showed that the highest body weight was found in treatment 2 rabbits/ cage and rabbit fed diet with 1% lycopene. The best feed conversion ratio was found in treatment 2 rabbits /cage (3.32), followed by 4 rabbits/ cage (3.43), while the poorest value was determined in treatment 6 rabbits/ cage (3,68). The economic efficiency was decreased from 1.17 to 0.96 as the number of rabbits increased from 2 to 6 in the cages. Therefore, it could be concluded that under heat stress, raising rabbits in cages with low density and supplemented with 1% lycopene in diet gave the best productive performance and improved the economic efficiency. At the same time, raising rabbits in low density, permits for somewhat motor activity and social life which reflect on the meat quality and increasing the selling price.}, keywords = {density,Phytobiotic,Rabbit,summer season,heat stress}, url = {https://jsas.journals.ekb.eg/article_5220.html}, eprint = {https://jsas.journals.ekb.eg/article_5220_d15a75c84fc324dd46756c8f2336ee7c.pdf} } @article { author = {Mariey, Samah}, title = {Genetic Diversity Study of Egyptian Barley Cultivars using Sequence-Related Amplified Polymorphism (SRAP) Analysis for Water Stress Tolerance}, journal = {Journal of Sustainable Agricultural Sciences}, volume = {44}, number = {1}, pages = {21-37}, year = {2018}, publisher = {The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)}, issn = {2536-9571}, eissn = {2536-958X}, doi = {10.21608/jsas.2018.2604.1051}, abstract = {A two-year field screening analysis was evaluated to study the analysis of variance,  mean performances, principal components analysis (PCA)  and similarity levels among  19 Egyptian barley cultivars for six parameters during two consecutive seasons 2013/2014 and 2014/2015 to identify their response to water stress conditions. The results exhibited significant differences among all cultivars for all studied characteristics, and highest mean values for all studied traits have been detected for Giza 2000, Giza 131 and Giza 126, which had positive and highest values of PCA. Also, highest similarity levels were observed among these cultivars with more than 90%. So we could consider that these cultivars as tolerant to water stress. Molecular marker analysis was used as a new molecular marker called sequence-related amplified polymorphism (SRAP) to determine the genetic diversity and relationships among 19 Egyptian barley cultivars for water stress tolerance. Nine selected primer combinations were amplified and gave 71 total fragments, at which primer combination “me5+em1” gave the highest polymorphism (100%) and the highest polymorphic information content PIC was (0.97). The dendrogram of SRAP markers had clustered all the Egyptian cultivars into four groups; each group includes the most closed cultivars together according to their response to water stress. Results showed that the SRAP marker technique could be efficiently used to assess genetic variation among Egyptian barley genotypes and their ability for tolerance to water stress. }, keywords = {Hordeum vulgare,Morphological traits,principal components analysis,water stress tolerance,SRAP marker,PIC,UPGMA cluster analysis}, url = {https://jsas.journals.ekb.eg/article_5593.html}, eprint = {https://jsas.journals.ekb.eg/article_5593_cb3c884553b95fd36445dea3ccb9ac74.pdf} } @article { author = {Ibrahim, Mayada}, title = {Rural Women’s Knowledge of The Harmful Effects of Some Manufactured Food on Children’s Health in Some Villages, Kafr El-Sheikh Governorate}, journal = {Journal of Sustainable Agricultural Sciences}, volume = {44}, number = {1}, pages = {1-12}, year = {2018}, publisher = {The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)}, issn = {2536-9571}, eissn = {2536-958X}, doi = {10.21608/jsas.2018.2656.1052}, abstract = {The aim of this research was mainly to study the knowledge of rural women about the harmful effects of some manufactured food on children’s health.

It is the target of the development process and the beneficiary of its positive effects. On the other hand, it is the main supplier of production, what makes the human resource the real wealth of poor countries as well as the most important factor for the efficiency and success of agricultural development programs of those countries. The agricultural quarantine is regarded as the first line of defense to protect countries against imported infections and pests, as well as protecting consumers against agricultural commodities that are not conforming to standards and specifications. In 2015, the rate of exports and imports examined by Egyptian quarantine was estimated to be 57% of total agricultural exports and imports, a matter that initiates the importance of studying the efficiency of the employees working in the agricultural quarantine in performing the required role in the agricultural development process. The research aimed mainly at identifying the efficiency of Egyptian quarantine workers based on the models of the regression of the dependent variable, “probability regression model”, that is Logit - Probit - Poisson - Tobit Regression. The research is conducted in 2017, preliminary data is obtained by questionnaire, 70 cases of workers in the Egyptian quarantine from a total of 789 workers having a bachelor degree or more - i.e. representing about 10% of the total number of employees in Quarantine- have been participated. The results of this study show that an increase in wages by one pound leads to increase the possibility of workers efficiency in the agricultural quarantine by, 0.002 units, according to Poisson model. An increase in the years of age by one year leads to increase the possibility of workers efficiency in the agricultural quarantine by about, 0.214 unit according to Poisson model. An increase in the educational level by one level leads to increase the possibility of workers efficiency in the agricultural quarantine by about 0.155 units according to Poisson model.
