Tomato crop is considered one of the most important strategic green crops at the national level. It is one of the food and manufacturing crops that some food industry uses it as pasle, it is alse an important source in its contribution to the Egyptian national agricultural income.<br /> The research aims at estimating the response supply for winter tomato crop in Egypt to determine the most important variables that can affect the response of the cultivated area of this crop. In addition to estimating the flexibility of the response to these variables, and the amount of the annual response to tomato farmers, and thus reach to the appropriate period necessary to achieve complete response. The response functions show has been estimated in accordance with the model of Marc Nerlov, and the model of Robert Solow.<br /> The results of estimating the response supply of the winter tomato crop in Egypt using the model Marc Nerlov for partial adaptation during the period (1995-2013) have shown that the production of the <br clear="all" /> tomato crop per feddan is one of the most variables impact on the farmer's response to the expansion for the cultivation winter tomato., it has Also been clear that there is a response from winter tomato growers to the relative prices between the winter tomatoes and both of the sugar beet and beans. Besides that the results of estimating the response functions show for the winter tomato crop have shown according to the model of Robert Solow that the production of the winter tomato crop per feddan is considered one of the best variables impact on farmer's response to the expansion for the cultivation winter tomato. It has also, been clear that there is a response from the winter tomato growers to the relative prices between the winter tomatoes and both of the sugar beet and beans crops. The research recommends the need to activate the role of agricultural guidance and expansion of the establishment of the indicative fields in order to encourage farmers to use tomato varieties with high productivity. The research, also, recommends the expansion in tomato manufacturing so that it can make a kind of balance between the quantity demanded and the quantity supplied and thus the possibility of maintaining the price stability.

Farmland infringement for the purpose of construction has become a serious problem in Egypt that negatively affects the average per capita of arable land and soil fertility in Egypt. On the other hand, this situation negatively affects Egypt's self-sufficiency rates of agricultural commodities, agricultural income, and employment in rural areas. However, farmland infringement is completely forbidden by the Egyptian agricultural legislation.<br /> In this regard, the current research aims at evaluating the impact of the Geographic and placement impact on Farmland infringement in Egypt during the period (2005-2010).<br /> This study recommend the importance of reduce farmland infringement in different Geographic places, to increase the Egyptian agricultural production, raise Egypt's self-sufficiency rates of agricultural commodities, and reduce the deficit in agricultural trade balance, and reduce the problem of unemployment in rural areas. Moreover, the current study used descriptive and statistical analysis to achieve its goals.<br /> The main results of this research showed that the total area of agricultural land that had been infringed during the period (2005-2010) reached about 4031 feddans during the period (1993 –1995), <br clear="all" /> increased during the period before revolution (1996 2010-) to 28788 feddans and increased more after revolution during the period 2011- 2014 to ( 38046) feddans. By calculated the total yearly average of farmland infringement in Egypt, the result show that it was about 30.8 feddans during the period (1993 –1995), increased during the period before revolution (1996 2010-) to 43.3 feddans and reduced after revolution as a total to 34.8 feddans as a result of reducing the rate of farmland infringement in the civilization governorate by intensive security power. On the other hand the farmland infringement in all other this rate had increased in all geographic placements in Egypt. Where the yearly rate of farmland infringement in Delta of Egypt, Meddle Egypt and upper. Egypt reach about (43.1, 49.5, 41.2) feddans respectively before revolution, increased after revolution to (712.1, 405.8, 354.5) feddans respectively. It is clear that the delta Egypt has the highest yearly rate of farmland infringement, so it is important to control this rate in future.<br /> Besides, the results showed that the most important reasons behind farmland infringement by construction in Egypt are the dummy variable representing the Geographic and placement for the governorates’ and time. The economic model shows the increase of yearly average of total farmland infringement by about 74.4 feddans and the result was significant at the level of significance 1%. Moreover the yearly average of farmland infringement for Delta of Egypt, Meddle Egypt and upper Egypt by about (287.9, 101.7, 95.4( respectively.<br /> On the other hand, by using the dummy variable of piecewise to describe the situation after and before revolution in the different geographic and placement of governorates the results show the increase of the farmland infringement after revolution in delta of Egypt from 1136.4 to 2704.3 feddans and the results was accepted significantly at the level of 1%. The results show also the increase of the farmland infringement after revolution in middle of Egypt from 206.7 to 492 feddans and the results was accepted significantly at the level of 1%. Furthermore the results show the increase of the farmland infringement after revolution in Upper Egypt from 254.2 to 605.1 feddans and the results was accepted significantly at the level of 1%. <br /> <br clear="all" /> However, the results showed that the farmland infringement after revolution in Egyptian civilization governorates decreased as a results of strong security from -34.5 to -82 feddans and the results was accepted significantly at the level of 1%.<br /> Finally, the research recommends strengthening the importance of protected the Egyptian agricultural land specially in the highest geographic and placement governorates especially in delta of Egypt, middle and upper of Egypt by achieving the balance of investment between all these geographic and placement governorates and establishment the necessary desert villages to meet the needs of Rural households.

The research aimed at studying current situation improvement for grain crops production to meet international and domestic demand needs regularly with stable prices and standard specification, through analysis and assessment Egyptian price policy for crops subject of study, using policy agricultural analysis matrix, partial equilibrium model, measuring the impact of government interference on producers, consumers, foreign trade and government revenue as a result of implementing specific policy, and the impact of this on input and output utilizing efficiency, and on economic welfare on society and government revenue for those crops. The study indicates that, from calculating nominal protection coefficient, there was implicit subsidy for producers in the first period (2008-2010). In the second period (2011-2013) the subsidy decreased, taxes are imposed, and there was implicit taxes in the form of negative protection against producers and decrease in the consumer's subsidy proportion.<br /> As a result of studying domestic resource cost for the study crops, it showed that, the value of coefficient less than one to rice, wheat, and maize. Which indicate to the ability of the current economy to save foreign currency through domestic production, which reflect competitive efficiency in rice international market. The study also indicates the excessive in government revenue at the second period for all study crops, meanwhile there was deficit in the foreign exchange for wheat and maize, this is due to the decreasing in the domestic supply and the increasing in domestic consumption in light of low domestic price relative to international price. While there has been a decline in foreign exchange loss for rice in second period to first period reached about 45% because of the closeness between domestic prices and international prices. The loss in producers surplus for wheat and maize increased because of increasing in cost to returns, meanwhile it showed a decrease in producer net loss in the second period to the first period 12% approximately for rice because of farm price increase to reach the international price, also consumer surplus obtained advantages in all study crops in the tow period of the study. The study showed that, impact of net economic loss was negative at the tow period of the study for wheat and maize with a decreasing rate reached about 43% for wheat and 55%for maize, in contrast the net economic loss was positive for rice with decreasing rate reached about 62% in the first period.<br /> The research concluded with the following recommendations:<br /> - Implementing fair price policy in it domestic price relative to international price for the study crops.<br /> - Reduction direct and indirect taxes imposed on producers in ratio of 6% for wheat and maize crops and with 7% for rice.<br /> - Subsidy imported and essential goods producers to diminishing consumers and producers net loss, to diminishing producers' burdens borne, and to provide foreign exchange to the stat.<br /> The need to provide economical and political stable atmosphere to the success of developing and prices policies in developing countries.

Identifying the development relation between different sectors in the entire Egyptian economy (2006/2013) through using of social accounting matrix , containing in addition to data on the inputs and outputs of the productive branches in the economy, but among other things also data concerning the distribution of the various kinds of factor incomes over institutional groups and classes, the expenditures made by these groups on different types of commodities, and the savings and investment made by them. <br /> The research showed the existence of permanent deficit representing by 1.5% annually which grown especially after the revolution of January 2011, so there where retreat of the rate of growth.<br /> So, it was suggested to do more as possible dis aggregate into socio- economic groups. It will be reasonable to dis-aggregate households into socio-economic group which mean In this case do <br clear="all" /> more to the level and pattern of consumption, <br /> expenditure and income distribution, that is to say to dis-aggregate Egypt society as follow:<br /> - Regional differences (urban and rural-household).<br /> - Egypt level of the head of the household.<br /> - Access to productive forms of material wealth particularly agriculture and manufacturing wealth. <br /> So The foregoing demonstrated the importance of studying the changes in a macro variables which form the economic relations of social accounting matrix annually and can identify deficiencies and take all measures to avoid such shortcomings even took those incremental trend variables where this may include increasing volatility of investments requires more caution in directing those investments among different sectors, or they may be growing incrementally as imports that requires imports to be more identifying from the point of view. The nature and priorities of rationalization of imports and its component so all variables must be viewed in the same way to reach ultimately aims to increase incoming, reduce expenses and create surplus that support development.

Milk is considered as a rich food source since it contains essential nutrients which are necessary for natural and biological impact, and no other food items can be compared with milk which has high nutritional value and plays an important role in building and strengthening the bones of children and prevention of elderly osteoporosis. Calcium in milk plays an important role in reducing the rate of absorption of cholesterol and controlling body weight and blood pressure. Milk contains the basic components that consist of lipid, proteins, sugars and mineral salts in addition to a range of vitamins and enzymes.<br /> Results of researches indicate that amino acids structure in the camel milk is similar to the structure of insulin, and contains many amino acids such as Methionine, Phenylalanine:, Arginine, Lysine, Valine and contains high concentration of Albumin and Globulin.<br /> <br /> The most important characteristic of camel’s milk compared to the other dairy animals is that it contains natural protein compounds such as anti-poising bacteria, anti-lysozyme and anticoagulants. In addition, camel’s milk retains its quality and strength for 12 days at 4ºC, and more than 48 hours at room temperature because it contains substances that reducing the fermented bacteria activity of lactose sugar, it is noted that the reduction of the acidity rate of camel’s milk. Arabian’s used camel milk as a medicine of many diseases such as anemia, tuberculosis, diseases of aging, fragile bones and rickets in children. Camel’s milk is also used as a laxative. It has a role in the treatment of influenza, fever, hepatitis C, the dropsy and respiratory diseases such as tuberculosis and asthma as well as digestive diseases besides lowering the level of blood sugar and regulating heartbeat.<br /> <br /> <strong>The goal of the research is to</strong><br /> <strong> </strong><br /> 1. Identify the benefits of camel milk and comfort active compounds vital vitamins and minerals.<br /> 2.

This investigation was conducted for two successive seasons (2013 and 2014) in a private vineyard located at 64 Km of Cairo-Alexandria desert road to study the possibility of using organic products to reduce powdery mildew, which it is reflect in reducing yield and fruit quality of King Ruby grapevines. The chosen vines were ten-years-old, grown in a sandy loam soil, spaced at 1.5 X 3.0 meters apart and irrigated by the drip irrigation system, trained to bilateral cordon with spur pruning, and trellised by the "Y" shape system. The vines were pruned during the last week of January with bud load of (60buds/vine). Application of different biocontrol agents <em>Trichoderma harziamum</em>,<em> Trichoderma viride</em>, <em>Bacillus subtilis </em>as well as blight stop a commercial biocide which contains different isolates of Trichoderma forms in Arabic gum and potassium soap) were obtained kindly from central lab. of organic agriculture, ARC. Giza, in an attempt reduces powdery mildew of the plants.<br /> The results showed that all vital bioagents treatments significantly were reduced the powdery mildew disease compared with micron sulphur and control in both season. However, spraying mixture of <em>Trichoderma harziamum + Trichoderma viride</em> and blight stop gave the least disease incidence and severity which it is reflect to increase yield, achieve the best physical characteristics of bunches as well as improving the physical and chemical properties of berries.

This study was carried out during 2013-2014 and 2014-2015 seasons at a private farm located at Tokh district, Qalubia Governorate. Strawberry fruits ˝festival cultivar˝ to study the effect of active (7.5% O<sub>2</sub> +15% CO<sub>2</sub> or 10% O<sub>2</sub> +10% CO<sub>2</sub>) and passive modified atmosphere packaging (MAP) on preserving the quality parameters and extend the shelf life of fruits during storage at 0˚C plus shelf life at 10˚C.The results showed that active MAP inhibit the weight loss and decay percentage, maintained fruit texture, ascorbic acid, titratable acidity (TA) and decrease in color development during storage and shelf life. Passive MAP was less effective in reducing the loss of fruits texture, TA and ascorbic acid content. Untreated MAP (control) gave the highest values of weight loss and decay percentage and lowest values of texture, becoming more red and poor appearance after 15 days of storage at 0˚C + 2 days at 10˚C. The results showed also that the optimum gas composition of MAP tests for strawberry was 7.5% O<sub>2</sub> +15% CO<sub>2</sub>. No decay was observed in active MAP at 7.5% O<sub>2</sub> +15% CO<sub>2</sub> during the storage period plus shelf life. Furthermore, it also retarded texture, color, titratable acidity and ascorbic acid content. Finally, the study concluded that storage of strawberry fruits at active MAP of 7.5% O<sub>2</sub>+ 15% CO<sub>2</sub> improved storability of fruits, and maintained fruit quality and gave fruits with good appearance till of 15 days at 0˚C + 2 days at 10˚C without decay. The shelf life of strawberry after harvest can be extended to 3 days at 0˚C + 2 days at 10˚C by this treatment.

Superior grapevines fertilized with compost, biofertilizers namely (Bacillus megatherium, Bacillus curculanse and Azotoacter Chroococcum), humic acid and two slow release fertilizers namely ( rock phosphate and feldspar ) as a partial replacement of mineral N fertilizers during 2013 and 2014 seasons. Using all substitutes of mineral N fertilizers was favourable than using mineral N alone in enhancing all growth characters, total chlorophylls, nutrients, yield and berries characteristics. Both nitrite and nitrate in the juice were greatly declined in all N management treatments that included the application of all N sources. The best results with regards to yield and berries characteristics of Superior seedless grapevines were recorded on vines that received 60g N, 60g P and 120g K/ vine/ year ( mineral sources) plus compost II ( 40% cattle manure + 60% rice straw ) at 16 kg./ vine+ the three biofertilizers namely Bacillus megatheium, Bacillus circulanse and Azotobacter chroococcum + humic acid each at 10ml./ vine/ year.

The current study was performed to investigate effect of three water regimes as well as, three different soil conditioners on the yield and fruit quality of tomato. The studied water regimes were namely; 60, 80 and 100% of class A pan. However; the tested soil conditioners were “soil hanz”, “Olygo plus” and “Bioconditioner”. Impact of the two investigated factors was studied separately, as well as, the interaction. The experiment was carried out at El-Dolify Farm, Khatatba, Monofia Governorate during seasons of 2012/2013 and 2013/2014. Tomato hybrid Yara F1 was used in this investigation.
The obtained results confirmed that, using the “Soil hanz” due to the significant increments in all tested parameters related to the yield and the fruit quality. Moreover; interaction between “Soil hanz” and any of the three tested water regimes was significantly the best in number of fruits per plant, average fruit weight, early, marketable and total yield. In addition; it was concluded from the results that; chemical properties of the tomato fruits were improved by applying the “Soil hanz”. Concerning the water use efficiency, it was found that, all of the tested soil conditioners resulted a significant effect related to water use efficiency compared to un-treated treatment (control). Whereas, irrigated the tomato plants under this experimental condition confirmed the validation of using the 80% irrigation regime for irrigation without significant losses in the crop yield.

For improving the safety of filling cream, the Hazard Analysis Critical Control Points (HACCP) system was applied during different preparation process. Different biological, chemical, and physical hazards that may exist in every preparing step of filling cream were identified and control measures were used for controlling those identified hazards. Dried milk powder was identified as high potential hazard raw materials contaminated with pathogenic bacteria e.g. <em>S. aureus</em> and <em>Salmonella sp.</em> Whipping step in preparing filling cream was identified as critical control point. For improving the safety of preparing filling cream system, different control measures including, thermal processing (pasteurization), addition of natural preservatives (lemongrass oil and herbs of cinnamon, clove and anise) and reduction of pH (fruit pulps of strawberry, apricots and apple) were established. Different applied control measures could be used for improving the safety of prepared filling cream where different investigated microbiological criteria were reduced to acceptable levels especially pathogenic bacteria. In addition, different HACCP principles as the critical control points, critical limits, monitoring, corrective measures, verifications and records were established. Implementing the HACCP system during preparing filling cream can effectively ensure safety of this product and other food products contained filling cram especially bakeries.

The current study aimed to investigate the effect of microbiological treatment on improving the nutritive value of corn silage as animal feed. Dried whole corn plants were prepared and two ground silos (0.5 ton each) wereused for ensiling whole corn silage and inoculated by bacterial inoculant (containing <em>Lactobacillus plantarum</em> and <em>Entrococcus faecium</em>) at the recommended rate of 1/2g bacterial inoculants/liter of water/ton of fresh whole corn silage. The ensiling period lasted for 50 days. The criteria of response were determined by: the quality of treated corn silage, chemical characteristics and performance of rams, nutrients digestibility and nitrogen balance. Results for treated and untreated silage, respectively, showed that the silage had pH 3.71 and 3.69, Total Volatile Fatty Acids (TVFA) were 2.48 and 1.98 mmol/100ml, and NH<sub>3</sub>-N values were 6.1% and 6.41% (on dry matter basis). The values of organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE), nitrogen free extract (NFE) and ash content on dry matter basis, however, were very close in the two rations. There were no significant differences between the two rations for the dry matter (DM). The value of CF digestibility was not significantly different from that in treated corn silage, while ration contents of treated corn silage were significantly higher in OM, CP, NFE and EE digestibility than the untreated corn silage. Recorded values for total digestible nutrients (TDN) and starch value (SV) of rations of treated corn silage were significantly higher than those of untreated corn silage being 52.64 and 63.37 vs. 43.53 and 56.09%, respectively. The digestible crude protein (DCP) values were (7.43%) for ration of treated corn silage by 5.96% for the ration of untreated corn silage.
