This study reports for the first time the eco-physiological responses of some Egyptian wild beet accessions (WB1013, WB1021 and WB1026) under saline irrigation. The plants were exposed to five seawater salinities (0, 20, 30, 40 and 60% sws) for 6 weeks in a sandy culture in the greenhouse. Low salinity (20% sws) slightly enhanced the plant fresh weight of both WB1013 and WB1021 genotypes by 5% and 3% respectively, but significantly reduced that of WB1026 genotype by about 10%. Higher seawater salinities, however, caused progressive growth reductions in all accessions, with maximum growth inhibition, being 59% in WB1026 at 60% sws. Tolerance threshold was lowest (being at 20% sws) for WB1026, but highest (reached 40% sws) for both genotypes WB1013 and WB1021. EC50 was at salinity level of 40 – 60% sws for WB1026 genotype, but higher than 60% sws for genotypes WB1013 and WB1021. These indicate that both accessions WB1013 and WB1021 are more salt-tolerant when compared with WB1026. The higher salt tolerance of WB1013 and WB1021 accessions is largely conferred by higher leaf K+/Na+ ratio, due to low Na+ and Cl- accumulation under saline conditions compared to WB1026. This was associated with lower dry weights and ion leakage, and with higher leaf area, chlorophyll readings, total soluble carbohydrates and Ca2+ concentrations when compared with WB1026. Both WB1013 and WB1021 accessions do not only offer the possibility of being an alternative promising cash crops under seawater irrigation, but also, through an understanding of its physiology, may provide possible routes to enhance salt tolerance in other beet crops.

The heat shock protein (HSP) family is one of the proteins universally accumulated under heat stress condition. Four Egyptian maize inbred lines (Zea mays L.) were studied to identify heat shock proteins under heat stress at 45°C as protein markers for detecting the thermo-tolerance inbreds. The protein fingerprints of four inbred lines were performed by grain total-soluble protein electcophoretic analysis. The protein electrophoretic analysis showed 18 bands in a distinct pattern of K1 and K7 inbred lines, while 17 bands were present in G342 and Rg59 inbred lines as another distinct pattern indicating different genotypes. The high temperature effect on four maize inbred lines exposed to 45°C for 2 and 4 hours at 14-days old seedlings besides control (25°C) was studied. Several protein bands varied between low and intermediate molecular weights were induced after exposing to heat stress at 45°C. Four bands of heat shock proteins with molecular weights of 82, 22, 17 and 10 kDa appeared in the inbred line K1 after exposing to 45°C for 2 and 4 hours which may be indication of thermo-tolerance. Four and seven bands were enhanced after exposing to high temperature for 4 hours at 45°C which appeared more concentrated in the patterns of K7 and G342 inbred lines, respectively.

The microbial contamination of the female genital tract has effect on the ivf outcome and negatively effect on fertility, fertilization and implantation rate. Lactobacillus sp. is the dominant organism of the vaginal flora that have an important role in the inhibition of pathogen. 48 patients were selected for this study aged between 20-40 years, During embryo transfer, 3 samples were collected from each patient from vagina, end cervical canal and the tip of the catheter. The samples were assayed microbiology. The microbial culture contained natural flora and pathogen organism .The isolated pathogens were identified as Klebsilla pneumonia, Escherichia coli, Candida albicans, C. tropicalis, C. famata, C. parapsilosis, C. catenulate according to Bergeyˊs manual and confirmed by VITEK System. Candida sp found to be the most frequent infemale genital tract. The probiotic (Lactobacillus. acidophilus) and its metabolites (bacteriocin) were inhibited growth of isolated pathogenic microbial  in vitro.The result showed that L. acidophilus and their metabolite bacteriocin have antagonistic activity against pathogenic microbes.                 Recommendation: Oral or transvaginal administration of Lactobacillus or bacteriocin antiseptics; disinfected; maintain a health vagina and prevent the infection of the reproductive tract.

Hepatoprotective effect of ethanol extract of ginger, ginger oil or rice bran oil against fatty liver disease which induced by ethanol stress was investigated in the present study. Thirty six (36) male albino rats were classified into 6 groups as follows: 1- Normal control (NC), 2- Positive control (induced fatty liver by ethanolic stress) (PC+), 3- rats group administered ethanol and ginger extract (GE group), 4- rats group administered ethanol and ginger oil (GO group), 5- rats group administered ethanol and rice bran oil (RBO group) and 6- rats group administered ethanol and DMSO (DMSO  control group, because GE, GO and RBO were dissolved in DMSO as a vehicle). Results revealed that hepatic triglycerides was significantly (p≤0.05) raised to 80.7 mg/g liver, in positive control (PC+), compared to 15.98 mg/g liver in normal control (NC). Also significant increase (p≤0.05) in levels of ALT (69.41 U/L), AST (62.98 U/L) and ALP (121.65 U/L) in PC+, compared to their levels in NC (23.35 U/L), (27.95 U/L) and (73.45 U/L) respectively. In addition, high significant level was observed in serum triglycerides (214.37 mg/dl), total cholesterol (TC) (99.81 mg/dl) and LDL cholesterol (47.75 mg/dl) in PC+, compared with its values in NC group: (74.22 mg/dl), (31.45 mg/dl), (4.21 mg/dl) respectively. However, significant (p≤0.05) decrease was noticed in HDL cholesterol level (9.18 mg/dl) in PC+, compared to NC (12.39 mg/dl). On the other hand, treatment by ethanolic ginger extract (200 mg/kg body weight) showed a hepatoprotective effect which confirmed by remediation the values of hepatic TG, ALT, AST, ALP, TP, Alb, besides serum TG, TC, HDL-C and LDL-C in GE group as compared with their values in NC and PC+. Moreover, treatment by ginger oil (200 mg/kg body weight) and rice bran oil (200 mg/kg body weight) displayed a protective effect in GO or RBO groups, but lower than GE. In addition, ethanol extract of ginger disclosed very high antioxidant activity (IC50 = 18.25 µg/ml) compared to both ginger oil (IC50 = 6714.38 µg/ml) or rice bran oil (IC50 = 1409.57 µg/ml). Finally the present study indicates that ethanol extract of ginger showed hepatoprotective effect more than either ginger oil or rice bran oil.

The study was designed to evaluate the effect of barley grain etiolated sprouts mixture with faba bean, Egyptian clover, wheat and rice hays to improve fodder value. Hays were used as media to etiolated sprouts of barley with three seeding densities (10, 20 and 30% w: w). Growing conditions of the system can produce between 12.8 to 38.38Kg of fresh fodder and 3.18 to 9.10Kg of dry fodder in 4 days from one kilogram of dry barley grains. The dry fodder per unit seed volume (Kg/Kg grain) was decreased with increasing seed density. Since hays were decreased but the nutrient content of the fodder, especially protein was increased. Barley etiolated sprouts improved quality of hays fodder from faba bean, Egyptian clover, rice and wheat crop. Carbohydrate lipid, protein and total energy content were increased with increasing barley-seeding density while crude fiber was decreased. In vitro dry matter digestibility (IVDMD) was decreased with decreasing seed density especially with rice hays (39.92) and increased with increasing seeding density especially with faba bean hays (74.77). Fiber fraction (Neutral detergent fiber NDF, Acid detergent fiber ADF, Acid detergent lignin ADL), cellulose and lignin percentage were decreased with increasing seeding density of barley, Relative feed value (RFV) was increased with increasing seed density for barley grown on faba bean, Egyptian clover, rice and wheat hays.                      The barley etiolated sprout production system obtained a good quality fresh forage in small area all year around and low cost estimated per ton DM; total digestible nutrients (TDN) and crude protein (CP) compared with hydroponic barely green sprouts. Therefore, the system can recommended as cheap energy (TDN) and protein (CP). In addition, the system saving agricultural lands and partially water consumption for strategy crop production as wheat and corn since its fodder products can produced and grown in small dark area during absence of natural forage.

This study was carried out to investigate the possibility of utilization of barley flour in production of pan bread. wheat flour of (72% extract) was replaced by 10, 15 and 20% barley flour. The effect of such replacements on physical and chemical characteristics of produced pan bread were studied. The results indicated that barley flour had a higher contents of chemical composition than that in wheat flour except carbohydrate content was the highest in wheat flour (85.53%) than in barley flour (76.67%),whereas, protein, ash, dietary fiber, β-glucan and antioxidant were higher content in barley flour (13.63, 2.44, 19.00, 8.65, 97.34 respectively) as compared with its content in wheat flour (12.26, 0.49, 4.88, 0.34, 55.33 respctively),while, wet gluten  and falling number were reduced by added barley in composite flour. The rheological properties of the  five dough mixes were studied using farinograph and  extensograph. The water absorption and dough weakening increased as the percentage of barley flour increased, while were decreased the extensibility and maximum resistance to extension . The results of sensory characteristies of prepared bread (containes10% barley flour) was not significants different from control for crust color, grain and texture. The results revealed that it was possible to use barley flour at level of 10, 15% to produce bread that satisfied baker's and consumer's sensory expectation. This levels may be to increased the nutritional value from dietary fibers, β-glucan, minerals, vitamins and antioxidants.

This study was conducted to investigate the effect of in ovo injection of broiler eggs with different levels and forms of selenium on growth performance and some blood parameters of post hatched chicks.  A total of 300 fertilized eggs obtained from a commercial Arbor Acres broiler breeder flock, were used in the present experiment. They were divided randomly into six treatment groups, 50 eggs each. The first one was kept as a control– non injected  group, the second group  (sham)  injected with phosphate buffered saline (PBS), the 3rd and 4th groups were injected with  selenium nanoparticles (SeNPs) at 10 and 20  ug/egg, while the 5th and 6th groups were injected with organic selenium (Se-Methionine) at 50 and 100 ug/egg , respectively.  All eggs were incubated in a forced draught incubator at the recommended temperature, relative humidity and turning patterns .The in ovo injection procedure was done at the 16th day of incubation. The criteria of response includes: live body weight, weight gain, feed consumption, feed conversion ratio, total protein, albumin, globulin, A/G ratio, cholesterol, triglyceride, HDL and glucose. The results showed that the supplementation of Se did not significantly affect growth performance traits. Supplementation of nano-Se increased plasma concentrations of total protein, albumin and HDL, and decrease glucose, however, no significant differences in globulin, A/G ratio, cholesterol and triglyceride levels. It can be concluded that the use of 20 ug /egg of Nano-Se caused an improvement of growth performance and feed conversion ratio without negative effects on blood constituents.

Food is a vital necessity for humans. Providing food in quantity and quality is not only necessary to meet biological needs or to achieve a decent standard of living, it is also an essential step for civilizational leapfrogging. The results indicate that the total Egyptian fish production increased at a statistically significant annual rate estimated at 57.2 thousand tons per year. The quantity of fish consumption in Egypt increases annually at a statistical average of 62 thousand tons per year. At a statistically significant annual rate of 0.44 kg per year, and the fish gap shows its fluctuation between the rise and fall during the period considered and the most important results of the consumer spending functions of the animal protein group in Egypt and the expenditure elasticities of these groups according to the economic and social factors that the expenditure on the animal protein group is generally higher. The results also showed the effect of both urban and rural on the consumption patterns of the animal protein group. The results indicate that the consumption expenditure patterns on the animal protein group in both rural and urban areas will be affected. In addition, the expenditure on urban animal protein will decrease in general from 2013 to 2015, countryside. The results showed that the household expenditure in Egypt has different and significant differences according to the annual expenditure categories of the private household, income, expenditure and consumption 2012-2013-2015-2016.

A 7x7 half diallel cross along with their parental wheat cultivars were evaluated under two sowing dates (19th Nov. and 17th Dec.).The results revealed that mean squares due to sowing dates, genotypes and genotypes x sowing dates interaction were significant for most of the studied traits. Delaying sowing date to Dec. reduced all studied characters compared to the normal sowing date except electrolyte leakage which increased by delaying sowing date. Heterosis over better parents showed that, the best hybrids under stress condition were Misr 2 X Giza 168 and Sids 1 X Giza 168   for grain yield / plant and some of other studied traits.  General and specific combining ability mean squares indicated the importance of both additive and non-additive gene effects in the inheritance of the studied traits with few exceptions. However, the additive effect was more important than the non-additive effects in the inheritance of days to 50% heading, plant height, No. of spikes/ plant,No. of kernels / spike and 1000-kernel weight while, the non-additive effects were more important than the additive effects in the inheritance of electrolyte leakage and flag leaf area. The best general combiner parents for grain yield / plant and some of other studied traits were Gemmeiza 11 and Giza 168under stress condition. The best hybrids for SCA effects were Sakha 93 X Sids 1, Gemmeiza 11 X Giza 168, Misr 2 X Giza 168 and Sids 1 X Giza 168 under stress condition for grain yield / plant and some of other studied traits. The crosses Gemmeiza 11 X Giza 168   (HSI 0.36), Gemmeiza 7 X Giza 168   (HSI 0.58) and Sakha 93 X Giza 168   (HSI 0.60) have recorded the lowest values of heat susceptibility index (HSI), indicating their tolerance to heat stress (late sowing date).

Agricultural sector is considered to be one of the most important sectors in the Egyptian economy that contributes greatly in the national income. Therefore, the state pays great intention to the agricultural sector concerning all developmental aspects either vertical or horizontal. That is achieved through developing used and already existing agricultural resources which is called vertical agricultural development, or through adding new agricultural materials which is called horizontal agricultural development. In all of the abovementioned fields, agricultural machines play an important and direct role in achieving both vertical and horizontal agricultural development, as it is well- known that vertical and horizontal  agricultural expand depends totally on agricultural machines in general and the developed modern machines in particular. As for vertical agricultural expand, agricultural machines play vital and effective role in increasing production, lowering production costs and the possibility of making use of the advantages and jumps of expansion through expanding in use and application of modern technical methods in agriculture as laser leveling, planting by seed drill, automatic seedling and automatic harvest. In addition to the abovementioned, there is the gab in the cereals, decrease of the net profit of farmers as well as their use of farming traditional methods that do not coop the agricultural development. Considering the importance of the technical standard as an important factor of agricultural production, the use of modern technology comes among the most important methods that may increase the production of Feddans by the optimal economic use of limited resources. The thesis aimed to introduce the best technical standards in agricultural machines applied in the farming rice, wheat and maize in order to yield the highest production with lowest costs and to gain the highest amount of net profit of Feddan. Moreover, the thesis aimed to study the production and economic indicators of the crops studied by the thesis and their development nationwide as well as comparing the effect of the technical processes on the productivity of the Feddan of the crops studied by the thesis and their effect from the economic feasibility point of view. This  part of the thesis deals with the economic evaluation of using agricultural machines in order to farm to wheat  in Egypt., as it was shown that the average Feddan productivity of wheat was estimated of about 3.7 ton/ Feddan as a result of using technical methods, whereas productivity by using traditional systems was about 2.8 ton/Feddan. This shows that as a result of using technological systems, Feddan productivity overcomes using the traditional systems as that increase was estimated to be about 0.9 ton/ Feddan with a percentage of about 32% from traditional systems. This increase in the average Feddan productivity for land unit reflects to new items, laser leveling, deep ploughing and adding land plaster with the relatively stability of varied production costs and the extent of technical and economic efficiency on favor of using technological systems. The thesis showed that the total proceeds of wheat farmed by using technological systems reached in average about 12440 pound/ Feddan, against 9560 pound/ Feddan for wheat farmed by using traditional systems. It was shown that the total proceeds of wheat farmed by using technological systems increase with a percentage of 30% from the same crop farmed by traditional systems. The study shows that the total varied costs of wheat for technological systems distributed on the production elements is estimated in average of about 3915 pound/ Feddan against 6390 pound/ Feddan for transitional methods with an increase of 39% when using agricultural machines. Moreover, the study pointed out that the total costs were estimated in average of about 5915 pound/ Feddan of wheat farmed by using technological systems against 8390 pound/ Feddan for traditional systems with an increase of about 29%. This illustrates the efficiency of suing technological systems. The study considered the net Feddan proceeds of wheat farmed by technological systems. It was estimated of about 6525 pound/Feddan against 1170 pound/ Feddan for traditional systems. This means that technological systems' net profit exceeds the same profits of traditional systems with an increase of about 5355 pounds. The study showed that the proceeds above the varied costs of wheat farmed by technological systems are estimated with about 8525 pound/ Feddan in average against 3170 pound/ Feddan for traditional systems. This means that technological systems are superior with about 169%. This increase is attributed to the increase in the total proceeds of technological systems comparing to traditional systems. The study shows that the cost of ton of wheat farmed by technological systems is estimated of about 3362 pound/ Feddan in average against 3414 pound/ Feddan for traditional systems. This means that technological systems exceed traditional systems with about 2%. This decrease is attributed to the increase of the Feddan productivity using technological system comparing to traditional systems. Considering the profit on the invested pound, it reached about 1.10 pounds for the use of technological systems against 0.14 pounds for the use of traditional systems. This shows that the technological systems used in farming wheat is better from both technical and economic point of view which means that the new technological systems used in production covers the total costs and realizing a surpass. This shows the efficiency of resource usage in producing wheat farmed by technological systems. Every pound being spent or invested in farming using technological systems achieves an income of about 10 pounds against one pound for traditional system.
