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.

Irrigation, water management under climate change conditions plays an important role in rationalizing water uses efficiency in the agricultural development processes specially under aridecosystems conditions. Therefore, the objective of this study was to estimate the irrigation water requirement of savings landscaping areas under different recent techniques. So, this study focused on comparison between fully automatic with central control system (C.C.S) based on weather station and Control unit based on operator experience and background. The experiments were conducted during two years (from January 2014 to December 2015), in the site that located in District 5, New Cairo, Cairo, Egypt.  The results indicated the irrigation scheduling based on weather station data using a central control system (C.C.S) optimized maximize the irrigation water use efficiency and increase the amount of irrigation water saving  by about  14%, 36%,18% and 33% in Autumn, Winter ,spring and summer  respectively  in year of  (2014) and 7%, 29.7%, 16%, 33% in Autumn, Winter, spring and summer,  respectively in year of  (2015) compared with the other irrigation scheduling when based on calculated according to traditional method. In addition,  the results revealed that scheduling practices based on weather station data by using central control system could reduce the average of power consumption (about 314 KW) in year of (2014) and (about 347 KW) in year of  (2015).  Moreover ,the results revealed that the cost of water consumption for the central control system based on the data of the meteorological station for the two years 2014 and 2015, the years of study  were 018601 L.E./ 2 years compared with the other irrigation schedule when calculated according to the operator's experience was 010101 L.E./ 2  years. Where the cost of 36172, 13603, 23393 and 33642  L.E./ 2 years in the winter ,spring, summer, autumn and respectively of the central control system and 39600, 17068, 28820 and 45522  L.E./ 2  years in the winter, spring, summer, autumn respectively of the other system.

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.

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.

The problem of food supply is the main problem that worries the world in recent times, and the problem of developing countries is increasing in size to increase population growth rate. The problem of research is the low efficiency of production and processing of dairy products in Egypt. In addition to the low level of dairy processing operations, the aim of the research is to identify the current production status of milk and dairy products and to identify the monthly seasonal prices of these products as well as the margins. The most important results were the annual increase in the production of the study products, which were studied and the focus was on these products due to the availability of data on them without other products. It is clear from the study of the general time trend equation in Table (2) Dairy production increased by a statistical significance of about 13.3 thousand tons, an annual increase representing about 1% of the average total production during the period (2000-2014), and it was found that the coefficient of selection was about 560. That is, 56% of the changes that occur in the quantity of production The total dairy production is due to changes in the variables (2) indicates that the production of buffalo butter increased by a statistically significant increase of about 1.9 thousand tons, with an annual increase representing about 2.3% of the average total production during the period. (2000-2014). It was also found that the coefficient of selection was about 0.61, ie, 61% of the changes in the amount of buffalo butter production are due to variables whose effect reflects the time component. It is also clear from the study of the general time trend equation in Table (2) that the production of Jamousian cheese increased by a statistically significant increase of about 1.9 thousand tons, with an annual increase representing about 0.77% of the average total production during the period 2000-2014. The selection was about 0.48, which means that 48% of the changes in the quantity of cheese production are attributed to changes in variables whose effect reflects time.
