This study was conducted out at the farm of Sakha Agric. Res. Station during 2014 and 2015 seasons to contribute in choosing best CMS, maintainer and restorer lines to use in hybrid rice seed production depending on its floral traits. Also, it can be used in a breeding program for improving the floral traits of other lines that can serve as good parents in hybrid rice breeding and seed production.In brief, we found that among the studied CMS lines,Pusa13A was the best line in stigma length, angle of spikelets opening, filament length,exertion ratio (%), number of filled grains panicle-1, seed set (%),panicle weight and plant yield characters, while Pusa13B line was the optimum owing to its high characters like, anther length, good filament length, high exertion ratio (%), number of filled grains panicle-1 and plant yield.For restorer lines, PR1 was the best in anther length, stigma length, stigma width, filament length, number of spikelets plant-1, number of filled grains panicle-1 and panicle weight.The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)Journal of Sustainable Agricultural Sciences2536-957143420171201Antiatherogenic effect of Tiger nut tubers (Cyperus esculentus L.) supplemented diet in apolipoprotein E knockout mice197204502310.21608/jsas.2018.1942.1031ENMohsen AbdelazizZommaraDepartment of Dairy Science, Faculty of Agriculture, Kafrelsheikh University, Kafr El-Sheikh, Egypt0000-0002-1090-5570KatsumiImaizumiKurume Institute of Technology, JapanJournal Article20171026The present study was carried out to evaluate the physiological effect of tiger nut tubers on lipid metabolism and peroxidation stress in apolipoprotein E knockout (apoE-/-) mice. Six male and five female mice, 6-7 wk old, was fed AIN 93G control diet supplemented with 25 % of whole powder of tiger nut tubers for 11 wk. Measurements were done for plasma, liver, aorta and brain lipid fractions. Peroxidation stress in mice serum and brain, i.e. vitamin E, nitric oxide and TBARS were evaluated and aortic valve lesions area was also determined. The obtained results showed that, type of diet and mice gender did not affect mice growth parameters. Serum and liver lipids were lowered in male mice fed tiger nut diet than that fed the control diet. However, the effect of tiger nut diet on the peroxidation parameters was not prominent. The mice fed on chufa-diet resulted in significant reduction in the aortic arch atherosclerotic lesions in both gender compared to that fed the basal diet. Our results show that tiger nut tubers have antiatherogenic effect and contain a gender dependent factor which regulates lipid metabolism in apoE-/- mice.The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)Journal of Sustainable Agricultural Sciences2536-957143420171230An Analytical Economic Study of Sugar Cane in Egypt151163559210.21608/jsas.2017.1832.1028ENRoshdy ShawkeyEladawyDepartment of agricultural economics,faculty of agriculture,kafrelshrikh unversity , egyptJournal Article20171013The study aimed mainly to measure the economic efficiency of resources used in the production of sugar cane in Egypt, estimate the optimal size of the production and its bulks profits, and estimate the efficiency of sugar cane production factories. The research based on secondary data during the period 1995-2016 , we used a descriptive and quantitative analysis of the data and estimated some economic and productivity efficiency indicators as well.<br />The most important results can be summarized as follows:<br />For the standard estimation of the sugar cane production functions, we confirmed of the effect of both the labor component, the rental value of the land element and the time component which reflects technological development.<br />For the standard estimation of the sugar cane cost functions, the optimal size of production was estimated at 50.9 tons, the optimum capacity was achieved at 1.04 acres and the size of bulks production profits 67.61 tons, was achieved at an area of 1.38 acres. The estimation of supply elasticity was shown to be less than 1 which indicates that the optimal policy for increasing production is cost reduction.<br />The efficiency of the sugar cane production factories was approximately 51.86% Abu Qurqas factory, 54.22% Gerga factory, 85.70% Nag Hammadi factory, 77.79% Deshna factory, 93.51% qus factory, 98.63% Armant factory, for Advo and Kom Ombo factories work with an operating capacity exceeding their design capacity of approximately 114.26% and 103.99% respectively. This indicates that the majority of these factories are not working at full operational capacity.<br />By studying the areas targeted for the sugar cane crop uses, it was found that 76.3% of the sugar cane was directed to factories, 3.93% for honey extractors, 3.81% for seeds, and 16.75% as fresh consumption.<br />recommendations:<br />To achieve economic efficiency we must rationalize the use of human labor, mechanical and animal forces.<br />The size of the farm must not be less than the optimal size of the production which is a 1.04 acres.<br />The size of the farm must not be more than 1.38 acres in order to bulks profits of farmers.<br />The necessity of operating the sugar cane factories at full capacity, either by reducing the quantities of leaks or by increasing the sugar cane through increasing its area or productivity, and work on updating , developing and benefiting of technological development.<br />Work on the development of new varieties of sugar cane with low water requirements.<br />Attempt to develop a strict law that obliges farmers to supply their entire crop of cane to sugar factories without any other uses, especially in the main production governorates.

Economics, Fac. of Agriculture, Kafrelsheikh UniversityJournal Article20171128The issue of food security and food security is of concern throughout the world in general and in the third world in particular. The importance of milk and its products is increased because of its high nutritional value, as it contains many essential elements such as vitamins, mineral salts, protein, Suitable for body needs.The amount of milk production in Egypt in 2014 amounted to about 6,126 million tons, estimated at 27.1 million pounds representing about 9.57% of the value of agricultural production of about 283.1 billion pounds, and about 24.2% of the value of animal production of about 112 billion Cattle contribute about 50.3% of the total milk production capacity, while buffalo contributes about 47%, while goats contribute only 2.7% of total production.It is very important to increase the capacity of milk production and its products to increase the local supply of these important products and reduce or prove their prices. It is necessary to attract capital to establish new facilities for this industry and increase investment in this field to achieve stable prices in the dairy market.The problem of this study is concentrated in the existence of a food gap between production and consumption, which causes an increase in the prices of milk and its products. It also forces the state to import from abroad to fill the deficit, which negatively affects the Egyptian economy.The general objective of the study is to estimate the economic efficiency of the sample plants and to identify their economic indicators.In light of results, the research recommended that advantages of production and large capacity savings that lead to lower costs and access to the best possible efficiency. Increasing the volume of raw milk product to eliminate the Lebanese gap and access to self-sufficiency, as well as increase the average consumption to reach the global levels. Start the establishment of factories to manufacture milk powder and this helps to reduce the loss of milk and liquid storage as long as possible.Raising the efficiency of workers to increase their productivity in quantity and quality, which leads to increase the value of production and profits and helps in raising the efficiency of this industry.Greater attention should be given to the exploitation of idle capacities in dairy factories, which can increase the returns and profits of these factories without adding new investments.Working to facilitate access to licenses for the establishment of dairy products factories, which contributes to the increase in supply and hence the low prices, and this will increase our exports to the Arab and European market, which contributes to the progress of the Egyptian economy.To start applying the quality and safety standards in the Egyptian factories and monitoring the government with good supervision.The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)Journal of Sustainable Agricultural Sciences2536-957143420171201A descriptive study of the quality of agricultural websites175190514010.21608/jsas.2018.2205.1041ENManal FahmeyAliکلية الزراعة جامعة کفرالشيخ قسم الاقتصاد الزراعي شعبة الإرشاد الزراعيJournal Article20171129This research is mainly aimed at identifying the use of agricultural websites for the quality standards of websites through achieving the sub-objectives;1- Identify The quality of the agricultural web sites represented by the site of Our lands for agriculture and animal production, the site of the central administration of agricultural extension and environment, the site of Al-Ahram Agricultural<br />, the world of agriculture, the site of agriculture, the site of the Egyptian agricultural data, the site of Misr Agricultural Channel, the site of the agricultural newspaper Misr, and radcon wibsite. 2- Identify of the content of the agricultural websites.3 - Identify the quality of the design of agricultural web sites under study. 4 - Identify the quality of the organization of agricultural websites under study. 5- Identify of the ease of dealing with the agricultural websites in the study. 6 - Identify the order of agricultural sites in the study according to the number of visits within the Arab Republic of Egypt.The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)Journal of Sustainable Agricultural Sciences2536-957143420171201Problems Facing Farmers of the Faba Bean at Kafr El-Sheikh Governorate191203514110.21608/jsas.2018.2280.1042ENMona FathySalamaExtension Program Department, Agricultural Extension &amp; Rural Development Research Institute, Kafr El-Sheikh EgyptJournal Article20171211This research was mainly aimed to identify the problems facing farmers of the faba bean at Kafr El-Sheikh Governorate to determine the correlation and regression coefficients between those problems and the independent variables, and finally to identify the farmers’ proposals to overcome those problems. In order to achieve these goals, three randomly selected districts were selected in Kafr El-Sheikh governorate. Then, one village from each district was randomly selected: Dafriya (Kafr El-Sheikh), Al-Sahayt (El-Hamoul) and Wakf Bahery (Metobas). The random sample amounted to 153 respondents. A number of statistical methods were used: frequency, percentage, weighted average, mean, standard deviation, simple correlation and regression coefficients and stepwise regression model. The main results were as follows (1) - The problems faced the faba bean farmers were represented in seven groups. The problems’ groups facing the faba bean growers were classified according to their relative importance from the respondents’ as follows: extension problems, Followed by administrative problems, production problems, marketing problems, problems related to the grower, soil problems, and finally irrigation and drainage problems. (2) - The results indicated that the most common extension problem was the absence of the role of agricultural cooperatives in crop marketing. The most common administrative problem was the government stop farmer subsidization. The most common production problem was the high prices of different inputs. (3) - There was a significant negative correlation between the problems facing the faba bean farmers and the following independent variables: the education degree of the respondent, agricultural land tenure, experience at bean cultivation, exposure to extension activities and readiness for change. (4) - The most important proposals to overcome the problems facing them in the field of faba bean cultivation were: provide the production inputs (fertilizers and pesticides) at an appropriate price in the agricultural cooperatives, followed by identifying an indicative sale price before planting time.The National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology(ASRT)Journal of Sustainable Agricultural Sciences2536-957143420171201THE EXPECTED ECONOMIC POSSIBILITIES FOR ACHIEVING FOOD SECURITY OF LIBYAN WHEAT205211521710.21608/jsas.2018.2425.1047ENZahra S.HSalehDept. of Economics and Agribusiness, faculty of Agriculture, Alexandria UniversityNashwaEltatawyDept. of Economics and Agribusiness, faculty of Agriculture, Alexandria UniversityMouniraEL – HazekDept. of Economics and Agribusiness, faculty of Agriculture, Alexandria UniversityEL-HusseinEL - SeifyDept. of Economics and Agribusiness, faculty of Agriculture, Alexandria UniversityJournal Article20171227Wheat is a major strategic commodity in Libya.
