With the full recognition that the problem of inflation in Egypt is due mainly to factors related to the recent economic policy, while others are related to structural reasons, that ignited the flames of inflation led by monopolies prevailing in the commodity market. The problem is the rise in food and drink prices (FCPI) in particular. The problem is further compounded by the increase in poverty in Egypt, which rose to 31.8% in October 2017. The most serious is the increase of extreme poverty rate of 5.8% of the population is mainly due to rising food prices.  The research is concerned with the analysis of general price index and the food price index in four regions, namely, rural upper Egypt, urban upper Egypt, rural lower Egypt, and urban lower Egypt.  The research compare between the evolution of consumer price indices in two period, the first period cover, 22 months before the adoption of the  floating exchange rate policy and second period cover 15 months after the adoption from November 2016 of the new policy and it.  The main of the research are summarized in the following points:   1- Increase the general index of prices and number.                       2- A marked increase in the indices in the geographical areas in the countryside from the urban during two periods.                             3- There is a significant effect of the time component on the increase in the price index during two periods of study, which was more evident in the float period.                            4- The food price index had a clear effect on the increase in the general price index in the regions.  5- The conditions of the increase in the monthly inflation rates in the pre-flotation period in the Egyptian geographical regions, although there was a decrease in the floating period over time, in the floating period.              6- High urban inflation rates for rural areas, despite their rise.

Water resources are among the most important determinants of horizontal expansion in Egyptian agriculture. Given the scarcity of these resources on the one hand and the fact that they are relatively stable over time, the widening gap between supply and demand of those resources is increasing and the population is increasing and meeting their needs from various sectors. The problem of rationalizing water consumption and preserving its quality is an urgent national endeavor. As the Egyptian agriculture consumes most of the water resources, the problem of rationalizing the use of water in agriculture has become difficult to achieve in order to achieve the objectives of horizontal agricultural expansion. In this sense, the search for the most appropriate ways to exploit water resources has to be taken into account. The study aimed to identify the method of restructuring some of the irrigation systems in Kafr El-Sheikh governorate and the most important economic and environmental impacts it has caused in the study area through water transfer and distribution systems outside and inside the field through the canal and improved channels. With the aim of working on the best use of water as a rare economic element needs to rationalize its use over time, which helps to achieve the highest possible economic return and the lowest environmental loss possible and maximize the effects of economic and envir onmental positive and minimize the negative effects in areas developed irrigation systems.      It was also found that the net yield of cultivated acres of land using traditional surface irrigation amounted to about LE 5108, whereas in the land used, the surface irrigation developed was about 7258 pounds, an increase of about 2150 pounds, which is about 42.1% compared to land using traditional surface irrigation. It was found that the marginal income of the wheat crop cultivated in the land using traditional surface irrigation was about LE 3288, whereas the marginal income of the wheat Used for irrigation developer surface about 4227 pounds, an increase of about 939 pounds, with an average of about 22.2% compared Ppalarad used for traditional surface irrigation  and the net yield of cultivated rice fed in land using traditional surface irrigation was about LE 2270, while the ratio of land used for developed irrigation reached LE 4948, an increase of about LE 2678 representing about 117.9% compared to land using tradetional surface irrigation. For the rice crop of the land used for conventional surface irrigation was LE 1635, while the marginal income in land used for surface irrigation was LE 2282, an increase of LE 647, or 39.6% compared to land using conventional surface irrigation.  The increase in net income to average variable costs from about 71.94% for the rice crop cultivated in the land used for traditional surface irrigation was shown to be about 100.92% for the cultivated land used for advanced surface irrigation, an increase of about 29% at a rate of about 68.7 compared to land using traditional surface irrigation.

The study aimed to identify and compare changes in  consumer spending patterns in general and food expenditure in particular in both rural and urban areas during the period (2004 / 20052014 / 2015) Moreover  and the economic and monetary changes affecting the standard of livinghas also made in Egypt.  The study was based on quantitative and descriptive statistical methods such as arithmetic mean, rate of change and percentages, estimating the marginal slope of expenditure, and the elasticity of expenditure of the main food groups, and use of some quantitative analysis methods as a test of the difference between the average of two independent samples, (2004/05, 2014/2015), as well as some studies and research related to the subject of the study.  The results showed that the percentage of expenditure on food and drink in both rural and urban areas decreased from the total annual expenditure per capita in 2014/2015 compared to 2004/2005 and that it ranked first among the various expenditure groups during the two study periods and vice versa to the low rate of expenditure on housing in rural areas, the urban expenditure rate increased during 2014/2015.   The results showed that the relative importance of urban rural food expenditure, which was reflected in the reduction of the rural-urban food gap, increased from 27.6% to 14.5%. And vice versa, the percentage increased of the rural- urban nonfood gap, from 50.6% to 42.8% during the two study periods. However, the statistical is no significance of the difference between the average of two samples for the total expenditure, food and non-food between rural and urban during the two periods.  Results also showed an increase in expenditure on some food groups such as meat, vegetables, cheese, eggs, fish and non-alcoholic beverages, and the decrease in per capita expenditure on cereals and bread in both rural and urban areas during 2014-2015 compared to 2004/2005  The results showed the variation in the elasticity of the expenditure of the food and drink group in both rural and urban areas, some of which were necessary and some of them were morenecessary during 2004/2005. However, they increased per capita in rural areas for all food commodities during 2014-2015, However, most of the food commodities in urban areas is necessary commodities.  With reference to the political and monetary changes that occurred during the last ten years, the results of the study showed that the percentage of families living below the poverty line in the rural areas and their urban rise in 2014/2015 compared with 2004/2005, which means that the urban poor are more affected by their rural, The percent age of households living below the absolute poverty line in both rural and urban areas decreased in the second year compared to the first year. The percentage of non-poor households in both rural and urban areas increased in the second year compared with the first year, which indicates improvement Relative to the living conditions of some rural families, While in urban areas, the decline in the proportion of semi-poor families and the increase in the proportion of both poor and non-poor  households makes the change in living standards either positive or negative, but the study suggested that there was a transmission to those who were on the edge of poverty to below the poverty line, A change in the consumption pattern, which was affected by the high prices of most food commodities, especially meat and poultry and try to find different alternatives, whether from fish or from eggs and milk derivatives.

Sugarcane (Saccharum sp. hybrids) is a C4 grass used as a major source of sucrose. Invertase enzymes hydrolyse sucrose into hexose sugars reducing the production markedly. Soluble acid invertase role is always a case of discussion for having a major or minor role in the breakdown process in sink tissues. Bio-deterioration is another serious problem accomplishes the sucrose production, the delay between harvest and milling of sugarcane cause enormous depreciation in cane tonnage as well as sugar recovery. Beside another many factors, it was improved that both neutral and acid invertase present in cane stalk and both have tendency to increase after harvest. In the present study, sugarcane cultivar G.99/103, Saccharum  officinarium, was used to establish Inplanta transformation experiment for down-regulation of soluble acid invertase gene using siRNA application. The transgenic plants were examined chemically and genetically to estimate the percentage of silencing and its impact on the sucrose content. The enzyme activity showed reduction compared to control in most transgenic plants and consequently the decrease in expression level of soluble acid invertase increase the Brix value significantly in some of the transgenic plants.

The present work was aimed to evaluate Chenopodium quinoa cultivar CICA (Chenopodium quinoa Willd. cv. CICA), in field experiments, as a new and non-traditional leafy crop in Egypt under saline (ECe 17.9 dSm-1) and non-saline (ECe 1.9 dSm-1) soil conditions. Production of biomass, some morphological, physiochemical and yield components traits were estimated at 40 days from sowing date. Biomass production of young quinoa shoot under saline soil was significantly higher by 25% than non-saline soil. Quinoa plants cultivated under saline soil also showed significant high performances for most of morphological traits. Although salinity led to accumulate Na+ concentrations in the leaves by six folds higher than that found in the leaves produced under non-saline soil conditions, but no significant reduction has been observed for K+ concentrations. Moreover, salinity was significantly increased magnesium concentrations in quinoa leaves. On the other hand, no significant increase has been detected of proline or total soluble carbohydrates concentrations in leaves of quinoa grown under saline soil as compared to non-saline soil. This clearly indicated that quinoa plants, during early growth stage, tended to utilize inorganic ions rather than organic solutes to regulate its osmotic potential under saline conditions. Chlorophyll a, chlorophyll b and carotenoid concentrations were significantly decreased under saline soil. Also, concentrations of crude fiber, crude fat and iron in the leaves of quinoa plants grown under saline soil conditions were significantly decreased. Meanwhile, salinity has no significant influence on crude protein concentrations. These results revealed that the quinoa has the ability to grow and produce considerable high leafy vegetable yield with good quality, in terms of high protein, in land unsuitable for conventional vegetable crops.

The aim of the present work to study the effect of foodtypes (sugar syrup fortified with Garlic (Allium sativum), Lemon (Citrus limon), Garlic plus Lemon), pollen grains and plain sugar syrup (1:1)) on contamination of honey with bacteria, fungi and yeasts. The data indicated that application of sugar syrup plus extracts of garlic, lemon, garlic plus lemon or bee pollen led to decrease population of bacteria, fungi and yeasts compared with control treatment (plain sugar syrup 1:1). The fungi were the least population in all the treatments compared with bacteria and yeasts, meanwhile population of bacteria were moderately and the yeasts were the most occurrence. Garlic plus lemon treatment was the most effective against population of microorganisms, but garlic and lemon separate were moderately effective and bee pollen treatment was the least effective compared with other treatments. According to isolation and identification procedures, three bacterial species (Bacillus brevis, Bacillus cereus and Clostridium botulism), four fungal species (Aspergillus apis, Aspergillus niger, Cladosporium sp. and Penicillium sp.) and three yeasts species (Debaromyces sp., Lipomyces sp. and Saccharomyces sp.) were determined according to cultural, morphological and physiological characters. Cladosporium botulism bacterium was the most frequency compared with other bacteria species, but Aspergillus apis fungus was the most frequency compared with other fungi species and Lipomyces sp. was the most frequency compared with other yeasts.

growing seasons of 2013-2014 and 2014-2015, in a private farm at El-Salheya El-Gedida City, Ismailia Governorate, Egypt, to investigate the effect of rice straw (RS) as alternative to sandy soil (SS) and drenching applications of potassium humate (K2-HA) at 2 g/l, potassium silicate (K2SiO3) at 5 g/l, and seaweed extract (SWE) at 0.5 g/l on improving growth of sweet pepper (capsicum annuum L.) plants under deficit irrigation every 2 (I2), 3 (I3) and 4 (I4) days in addition to daily irrigation (I1) as control. Plant samples were taken at 90 days after transplanting to record leaf area, shoot fresh and dry weights, in addition to, determination of leaf relative water content (LRWC), concentrations of  N, P, K and Ca. Mean values of drenching applications showed significant increase in the growth parameters ;shoot fresh and dry weights, leaf area, LRWC, as well as, concentrations of  N, P and Ca in the two seasons comparing to untreated control and the best results were due to K2-HA followed by SWE then K2SiO3. The highest concentration of  K was obtained by K2SiO3 followed by K2-HA then SWE. Plants were grown on RS showed significant increase in LRWC comparing to plants were grown on SS. Plants were applied with I2+ K2-HA+ SS showed the highest significant value of shoot fresh weight, shoot dry weight, leaf area, N, P and Ca concentrations followed by I2+SWE+SScomparing to control plants applied with I1+ SS without drenching applications. Plants were grown on RS showed significant increase in growth parameters comparing with control plants but less than those were grown on SS. The best results were achieved by I3 + K2-HA+ RS, I3 + SWE+ RS, I4 + K2-HA+ RS. Plants were grown on rice strawunderI3 irrigation and applied with K2-HA or SWE showed significant increase in N, P and Ca concentrations, while, under I4  irrigation an increase in N and P concentrations was obtained by K2-HA.The highest concentrations of k were observed with plants grown on SS under the highest level of irrigation deficit I4 by K2SiO3.It could be concluded from the present study that rice straw could alleviate the negative effect of low water supply and applications of K2-HA and SWE are recommended for enhancing sweet pepper growth and nutrient elements uptake under water deficit conditions.

This investigation was carried out to study the effect of calcium chloride and storage period on fruit quality of Golden delicious apple cv. Collected at mature stage from private farm at Elbeida region. The fruits were stored at refrigerators of Horticultural Department, Faculty of Agriculture, Omar Al-Mukhtar University. Through the growing season of 2014/2015. The University, through 0.5 and 1% treatments contained three CaCl2 concentrations vis. 0, at five storage periods (0, 1, 2, 3, 4) weeks. Obtained results revealed that using CaCl2 at both concentrations improved most fruit quality parameters throughout storage periods.

The present Avian Influenza epidemic in Egypt is consider one of the major problems facing the poultry field and caused by circulation of genetically and antigenetically diverse influenza H5N1 viruses. This problem is controlled by applying vaccination. The objective was to determine the AI H5 recombinant vaccines efficacy (rHVT-H5, rFP-AI-H5 (Scotland and Ireland), k rND-AI and k rBuc-AI+ND) against classical and variant field HPAI H5N1 viruses in comparison to the traditionally inactivated whole AI virus vaccines as K R H5N1 / Egy, k H5N2 and k combined AI+ND vaccines. A single dose of the different types of vaccines either recombinant or inactivated whole virus vaccines was administered at different ages of chicken. Eight chicken groups were vaccinated with 8 vaccines and challenged after 4 weeks post vaccination to measure the protection %. Fecal and tracheal swabs were taken after 2 day post challenge to detect viral shedding. It was found that, live rFP-AI-H5 of both Scotland and Ireland strains induced poor clinical protection with high level of virus shedding. While, inactivated rND-AI, live rHVT-H5 and inactivated rBuc-AI+ND vaccines induced high protection rates ranged from 86.7% to 93.3% against both classical and variant HPAI viruses with a decrease or suppression of viruses shedding. In a parallel way, the inactivated whole virus AI vaccines either K R H5N1 / Egy, k H5N2 or k AI+ND induced a protection rates ranged from 85.7% to 100% with a high decrease in virus shedding levels. The data clearly indicate that inactivated whole AI virus and inactivated recombinant vaccines confers high levels of clinical protection with suppression in viral shedding compared to that of live recombinant vaccines except rHVT-H5 vaccine which induce a great level of protection and decrease in viral shedding in SPF chicken.

The response of different concentrations of α-amylase and ascorbic acid on rheological characteristics of weak wheat flour was studied by the three dimension polynomial quaternary model. Flour physicochemical characteristics, dough extensogram, bread texture profile analysis and sensory properties of pan bread were determined. All-purpose flour was treated by fungal α-amylase and ascorbic acid compared with strong flour which using for pan bread production, and then investigates differences of dough extensograms and pan bread quality characteristics. Predicting individual extensograph parameters (Y) was assumed by quadratic polynomial regression model for the independent variables (fungal α-amylase concentrations or ascorbic acid concentrations (X)) to optimize the extensograph parameters (Y) used regression analysis. Three-dimension contour plot was used as a method to study the response surface of different extensograph parameters (Y) as dependent variables with fungal α-amylase concentration and ascorbic acid concentration (X and Z) as independent variables. The obtained optimum predicting concentrations were verified, by using applied extensograph trials and then manufacturing pan bread. Using optimal predictive fungal α-amylase and ascorbic acid concentration levels give accepted extensogram parameters relationship r2 values and good pan bread quality, fit to the strong flour characteristics.
