The sorption isotherm and kinetic of Cu2+, Pb2+, Zn2+ , and Cd2+ ions onto sewage irrigated soil (El-Gebal El Aasfar-Qalubia) was examined as a function of the retention time and initial ion concentration using batch equilibrium sorption experiments. Results show that the Cu, Pb, Zn and Cd metal ions onto the soil is relatively rapid and sorption reaches equilibrium at about 240 minutes. Kinetics of the sorption process on the soil is well characterized by the pseudo-second order reaction rate. Langmuir, Freundlich and D–R isotherm models are fitted for the sorption of Cu2+, Pb2, Zn2+, and Cd2+ ions onto the soil. The constants of all models were calculated for each metal ion and compared. It indicated clear differences between the sorption characteristics of Cu2+, Pb2+, Zn2+, and Cd2+ ions on the sewage irrigated soil.

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% O2 +15% CO2 or 10% O2 +10% CO2) 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% O2 +15% CO2. No decay was observed in active MAP at 7.5% O2 +15% CO2 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% O2+ 15% CO2 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.

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. 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. The research concluded with the following recommendations: -       Implementing fair price policy in it domestic price relative to international price for the study crops. -       Reduction direct and indirect taxes imposed on producers in ratio of 6% for wheat and maize crops and with 7% for rice. -       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. The need to provide economical and political stable atmosphere to the success of developing and prices policies in developing countries.

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.

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. 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. 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 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.

The interaction of preservations, growth regulators and cold storage on vase life and quality of Lily (Lilium longiflorum) cut flowers were investigated. Lily cut flowers were treated with 1 ml mol silver thiosulfate (STS), 100 ppm gibberellic acid (GA3), 0.5 ml mol benzyl adenine (BA), 200 ppm citric acid and 4 % sucrose and then were placed in cold storage at 5 ºC for period of 1, 2 and 3 weeks. Vase life (days), fresh weight (%), total chlorophyll (%), total carbohydrate (mg / g d. w.), activity of catalase enzyme content (EU / 1 g f. w.) and amino acid of free proline content (mg / g d. w.) were determined. Cold storage for one week and pulsing with using material of GA3, BA and STS produced the longest vase life, the lowest catalase enzyme activity, the lowest content chlorophyll decreasing, the highest of total carbohydrate content and the lowest amino acid of free proline content.

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. 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.   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.   The goal of the research is to   1. Identify the benefits of camel milk and comfort active compounds vital vitamins and minerals. 2. Highlight the main role of biologically active compounds to improve and stimulate the immune system.

The objective of this research is to estimate price (direct and cross) and expenditure elasticities for major food commodities in Egypt. The food commodities are divided into six sub-models depending on the homogeneity within each group of commodities and the data availability quantities consumed and the corresponding retail prices for each individual item. Some commodities are aggregated in groups such as other beans, other vegetables, fruits(1), fruits(2) and oils.  The Linear Almost  Ideal  Demand  System  (LAIDS)  model  is  applied  in  estimating  a  system  of demand equations for each group of food commodities. To avoid the invalid inference and spurious regression problems that may be created by non-stationary data series, the Fully Modified Least Squares (FMLS) estimator is utilized.  The demand parameters satisfy the Engel aggregation, cournot aggregation, homogeneity and symmetry conditions.  The results indicate that expenditure elasticities of the majority of food commodities/groups are less than the unity except fot the fruits2 (1.110), indicating necessity effects. This can be also interpreted as following the increasing of consumptions of these commodities is strongly connected with increasing of all income levels. The results also show that the own price elasticities for food commodities/groups are inelastic. For fruits 2, its inelastic own price elasticity still indicates that it tends to be very sensitive to price changes. The relative high cross price elasticities in all sub-models illustrate the strong substitute or complementary effects of the price change of one commodity one quantities consumed from other commodities in the same sub-models. Therefore, structural implications from the estimated elasticities are important. The estimated own and cross price and expenditure elasticities must be analyzed during the economic reform for better understanding all economic changes affecting prices as well as consumption and expenditures.
