The present work was purposed to investigate the efficacy of culture filtrates periodic produced by Sclerotium cepivorum in vitro (15, 30, 45, 60 and 75 days) against onion white rot disease under laboratory and in vivo in the greenhouse along with how much effect on plant growth parameters. The incubation period needed for S. cepivorum to produce secondary metabolites was found as an important factor in control strategy using culture filtrate treatments. Results suggested that culture filtrates produced at different incubation periods, decreased linear growth, number and percentage of germination of well-developed sclerotia of the fungus also, increased the mean time of sclerotia onset. The least disease severity (16.67 %) was recorded with the treatment of culture filtrate 15 days old compared to infected control (91.67 %) and other used treatments. Sclerotia were not able to germinate with 15 days old filtrate at 100 % concentration for 72 hours of soaking. Screening of secondary metabolites by gas chromatography-mass spectrophotometry (GC-MS) revealed 30 compounds categorized into alkaloids, organosilicon, antioxidants, lipids, esters, alcohols and fatty acids. Under greenhouse experiment, treatment with 15 days old culture filtrate gave the best results in reducing disease severity, improving plant growth and increasing peroxidase and polyphenol oxidase enzyme activities compared with other treatments. Secondary metabolites of S. cepivorum in 15 days old filtrate could be a powerful alternative way to chemical fungicides. Further investigations are suggested to know which metabolite compound/s responsible about control process.

اعتبر العسل عند القدماء رمزا للصفاء والنقاء وسرا من اسرار الحياة . ولقد أثبتت الآبحاث العلمية فى العصر الحديث أهمية العسل فى علاج کثير من الآمراض مما زاد من قيمته الاقتصادية وشجع على کثرة الإقبال عليه فارتفعت أسعاره وازدادت أرباح المنتجين ومربو النحل. ويقوم نحل العسل بزيارة الآزهار لجمع حبوب اللقاح والرحيق أو إحداهما. وأثناء قيامة بهذه العمليات يقوم بتلقيح الآزهار مما يزيد نسبة العقد وبالتالى زيادة المحصول. تستهدف الدراسة بصفة اساسية دراسة اقتصاديات إنتاج عسل النحل بمحافظة البحيرة من خلال التعرف علي الوضع الانتاجي لعسل النحل فى مصر بصفة عامة ومحافظة البحيرة بصفة خاصة ، وتقدير دوال الانتاج وقياس الکفاءة الانتاجية للموارد الزراعية المستخدمة في انتاج عسل النحل علي محافظة البحيرة ،وذلک من خلال عينه بحثيةعشوائية عددها 102 مفردة منمرکز دمنهور کأکبر مرکز من حيث عدد المناحل حيث بلغت نسبتها حوالى 35% من اجمالى عدد المناحل بمراکز محافظة البحيرة . ولقد أوضحت الدراسة أن کل من الاقنعة والمدخن تمثل حوالي 70% من التکاليف الثابتة علي مستوي العينة ،فى حين تمثل الأدوية والتعبئة وسکر التغذية والصيانة أکثر من 80% من التکاليف المتغيرة .کما أوضحت مؤشرات الکفاءة الاقتصادية لانتاج عسل النحل في محافظة البحيرة افضلية الفئة الثالثة ( 200خلية فاکثر )حيث حققت اعلي عائد علي الجنيه المستثمر ،وفئة (100- 200خلية ) حيث حققت اعلي اربحية نسبية ويعزي ذلک الي الاستفادة من وفورات السعة الانتاجية لهذه الفئات وانخفاض تکلفة انتاج الکيلو جرام من عسل النحل بزيادة عدد الخلايا بالمنحل .

The research aims mainly to identify the training needs of extension workers in the field of climate change and its impact on fish production in Kafr El-Sheikh governorate. All the questionnaires were completed from the respondents in the study sample by 25%. The most important results were as follows: - 79.6% of agricultural extension agents have training needs and 54.0% of agricultural extension agents were represented in the low category according to36.3% of extension agents had no training needs, while 40.7% of the extension agents were in the low category according to their training need to know the phenomena of climate change. 13.3% of agricultural extension workers had no training needs, while 73.5% of agricultural extension agents were represented in the low category according to their training needs for the apparent impact of climate change. There are five variables that contribute significantly to explaining the differences in the training needs of agricultural extension agents for researchers in the field of climate change and their impact on fish production, namely: educational qualification, communication with agricultural resources, experience in agricultural work, and experience in the field of climate change. Fish production, job satisfaction.

Egypt is one of the countries with a clear scarcity in its natural agricultural resources. The agricultural sector is the main consumer of water, consuming 79.8% of the total actual water consumption annually, The total available water resources in Egypt is currently about 80.68 billion cubic meters, of which 55.5 billion cubic meters represent the annual revenues of the Nile River according to the agreement of shared Nile water between Egypt and Sudan in 1959, The research aims at identifying the role of water users associations at all levels by measuring and comparing the water use efficiency in Kafr El-Sheikh governorate inside and outside those links at the level of sub-distribution canals and mesqas level and estimating the production functions of the rice and wheat yields in KFS center within the study sample, The most important results were the loss of productive resources used in the production process in the undeveloped rice fields compared to the developed ones estimated at 31.16 hours of working hours, and there is an extravagance in the use of water resources in undeveloped fields compared to that in developed fields by about 919.75 m 3 as the average amount of water used in rice fields, Losses of productive resources used in the production process in undeveloped wheat fields compared to the developed ones were estimated at 8.18 hours of working hours, Excessive use of water resources the average amount of water used in wheat fields is 640.68 m3, which is a waste of water resources.

In view of the current situation and the study of the water crisis experienced by Egypt it is important to develop new concepts to rationalize water consumption, including the concept of water footprint to estimate the volume of water needed to produce the various commodities consumed by humans, Cereal crops in Egypt, rice, maize and wheat during the period (2000-2016), the research was based on secondary data, and the use of both descriptive and quantitative economic analysis methods As long as the general time trend equations, the water footprint estimation model and its indicators,The most important results were a decrease in the per capita water footprint of the rice crop by about 2%, and its per capita growth increased by about 1.7% during the study period, reflecting the positive impact of the agricultural irrigation policy of rice crop, while showing the increase of per capita water footprint of maize and a decrease in The per capita by about 2.68% and the per capita share of wheat increased by 4.2% and the per capita growth increased non significantly, reflecting a shortage of maize and wheat irrigation policy, The research recommends the need to calculate the water footprint of various crops, and recommends the need to address the shortcomings agricultural irrigation policy for maize and wheat crops, such as rice crop.
