Insect resistant soybean {Glycine max (L.) Merr.} cultivars could reduce pesticide use in controlling insects, resulting in less risk to the environment. This study was conducted to develop an effective field and SSR analysis screening procedurs to screen 15 soybean genotypes . A field experiment was conducted for their resistance , and showed that genotypesH105 andH153 recorded the highest insect resistance and low defoliation rating of 0.0 and 0.1 respectively, followed by H10L10A, L162, and H1L1. Genotype AGS-129 showed highest insect susceptibility and high defoliation rating of 4.0. Genotypes H10L10A, H 153, and H1L1 recorded the highest seed yield values due to the number of branches plant, number of pods plant, and 100-seed weight indicating that these genotypes could be recommended particularly with high resistance to cotton leaf worm. A total of 13 SSR primer pairs were used to generate 39 bands (alleles). Nearly 92% (12) of the primer pairs amplified SSR alleles of expected size and 11 SSR loci were polymorphic. The polymorphic SSRs were successfully used to differentiate among 15 genotypes. These markers could be particularly useful for genetic differentiation cotton leaf worm resistance.

Charcoal rot caused by Macrophomina phaseolina, is a destructive disease of sesame crop cultivated in Egypt. Eighty six sesame genotypes (Sesamum indicum L.) were used for evaluating disease resistance, in two successive summer seasons 2017 and 2018, in the field. Results obtained showed that highly significant variations were found between sesame genotypes tested in both seasons for disease infection percentage (DI %) and seed yield (SY). In season 2017, only 14 sesame lines No. 33, 3, 15, 64, 40, 63, 14, 39, 4, 16, 13, 80, 58 and 79, were classified as a moderately resistant (MR). These lines exhibited lower DI% of 13.33, 14.08, 14.44, 14.63, 15, 15.92, 16.67, 17.58, 18.33, 18.33, 18.51, 19.08, 20 and 20%, respectively. In the second season, traits of DI% and SY showed the same trend and closest means. The MR lines group, of the first season manifested the same disease reaction from first season, with one exception of the line No. 16 it was moderately susceptible with DI% increased to 25%. The combined data of DI% obtained from both seasons showed that 13, 21, 38 and 14 genotypes were MR, MS, S and HS, respectively.

The current research aimed to investigate the therapeutic effect of milk thistle (Silybum marianum L) seeds (MTS) powder compared with hepaticum drug on carbon- tetrachloride (CCl4) caused hepatotoxicity in rats. Thirty six female albino rats weighting 140±20g were divided into 6 groups. The 1st group was fed on basal diet as the negative control group (G1), while the other five groups were injected by CCl4 (i.p). The 2nd group was the positive control group (G2). Groups from 3rd to 5th were fed on basal diet contain different ratio of MTS powder 1, 2 and 3 %,respectively. While, the last group (G6) was fed on basal diet contain the hepaticum drug. Liver weight, relative liver weight to the body weight (L/B %), serum liver enzymes activity, total protein, albumin, bilirubin, kidney function, serum lipid profile and histopathological examination were determined. All data were statistically analyzed and the results showed that, milk thistle seeds are rich in protein, fat and fiber. Also, its oil rich in fatty acids as linoleic acid (55.12% ), oleic acid (21.78%) and palmitic acid (8.80%). Feeding hepatotoxic rats with 3 % of MTS and drug caused a significant (P ≤0.05) increase in liver weight compared to the positive control group. While, there was no significant differences (P >0.05) between the positive control group and therapeutic groups for L/B %. On the other hand, adding 1, 2 and 3% of MTS to standard diet caused a significant decrease (P ≤0.05) in ALT and AST enzymes activities level compared to the positive control group. Also, feeding hepatotoxic rats on 1, 2 and 3% of MTS and drug caused a significant (P ≤0.05) decrease in serum urea and creatinine levels. So, by increasing the levels of adding MTS powder (2 and 3%) to standard diet caused a significant improvement in liver function and histopathological examination.

Monosodium glutamate (MSG) is used to enhance the flavour in the preparation of food to improvement the palatability. However, it induces oxidative stress and causes many health complications. This work determines the effect of MSG on kidney and liver functions and to know the protective role of propolis in male rabbits. Twenty rabbits were divided into four equal groups. Group (1) used as control, group (2) received propolis (8mg/kg body weight), group (3) received MSG (50mg/kg bodyweight) and group (4) received propolis (8mg/kg body weight) plus MSG (50mg/kg bodyweight) in the same time as combination group. The doses was given every other day for 12 weeks. Monosodium glutamate significantly elevated the concentration of thiobarbituric acid reactive substances (TBARS) and significantly decreased the concentration of reduced glutathione (GSH) and antioxidant enzymes (Catalase(CAT), Superoxide dismutase (SOD), Glutathione S-transferase (GST), Glutathione peroxidase (GPx)) in plasma, kidney and liver. Activities of liver enzymes (lactate dehydrogenase (LDH), aspartate transaminase (AST), alkaline phosphatase (AlP), gama-glutamyl transferase (GGT), acid phosphatase (AcP) and alanine transaminase (ALT)), creatinine, glucose and urea were enhanced significantly, while globulin, albumin and total protein were reduced in plasma. Also, treatment with MSG resulted in the deterioration of the histological architecture in liver and kidney. The combination group alleviated its adverse effects on liver and kidney, and this protection might be due to the antioxidant properties of propolis. In addition, the histology of liver and kidney results were supported by the biochemical findings. From the obtained results, it could be concluded that propolis capable to mitigate the oxidative stress, hepatotoxicity and nephrotoxicity induced by MSG in male rabbits.

The Egyptian Government pays a great attention nowadays to encourage the agricultural investment in Sinai Peninsula. The current study focused on wadi Jerafi which is one of the most promising areas in North Sinai Governorate. The goal of this study is to evaluate the land capability classification of Wadi Jerafi basin using two universal software’s systems, namely as: MicroLEIS DSS (Cervatana Model) as semi-quantitative approach and Revised Storie Index as parametric approach. Accordingly, a grid soil survey was done through a total of 137 soil profiles. These soil profiles were investigated and sampled, then were chemically and physically analyzed. Based on soil variation in depth, gravel content and soil texture, seven soil mapping units (SMU) were delineated and evaluated to assess their agricultural capability. Cervatana Model classified the studied area into two capability classes; good capability (S2l) covering the largest area (63.25 %) and marginal capability (S3l) covering the lowest area (36.75 %). The most limiting factors are soil depth, gravel content, soil texture and/or salinity. On the other hand, Revised Storie Index (using Storie method equation) divided the land capability of the studied area into two classes unsuitable (N) which covers of about 60.87 % of the total area and marginal suitable (S3) covering of about 39.13 % of the total area. Another method of capability index calculation called Square Root Method was applied and therefore it distinguished three capability classes; moderately suitable (S2) covering 8.87 % of the total area, marginal suitable (S3) covering 75.39 % of the total area and unsuitable (N) covering 15.74 % of the total area. Accordingly, this paper recommend to implement Revised Storie Index as a parametric approach to evaluate the rate of each soil parameter and to use Square Root method to calculate the capability index of each mapping unit.

Abdelaty
Region of Alex-Cairo Desert Road (Egypt) has agricultural potentiality to contribute to food security; therefor the soil of the farm of Nile Company, at 63 Km Alex-Cairo Desert Road, was evaluated by applying our comprehensive analytical approach of evaluation. Soil physical and chemical characterization conducts to soil numerical classification and crops soil suitability that has the advantage to guide the practices of soil management and reclamation. Soil physical characterization leaded to univariate numerical soil classification that pointed that the major phases were moderately soil profile depth (1996.76 Feddan), moderately permeability (3543.90 Feddan), low holding capacity (2608.11 Feddan) and sandy loam textural phases (1800.83 Feddan). Soil chemical characterization led to univariate numerical soil classification which showed that the major classes were moderately saline (3124.76 Feddan), non-sodic (3531.04 Feddan) and non-calcareous classes (3851.35 Feddan). The study referred to selection salt tolerant crops as cultural practice for managing soil salinity. Leaching requirements (LR) of reclamation purposes, for different EC-tolerance crops, were determined to output GIS–EC edaphological map. This map that may guide the process of saline soil reclamation was composed of four mapping units having the area of 298.76, 3124.76, 845.35 and 16.11 Feddan. The map that determined the spatial distribution of (LR) application showed that: the max allover total leaching water requirements (ATLR) of 13189090.54 m3 are to cultivate all studied area by orange. (b) Wheat is more salts tolerant than orange. Accordingly, the max allover total leach requirements were 1557042.70 m3/studied soil to plant wheat, which were less greatly than the case of orange cultivation. GIS-ESP edaphological soil classification was elaborated by assigning ESP thresholds of tolerant crop range to GIS-ESP soil map to produce the GIS-ESP edaphological map. The map divided the studied area into three categories of ESP tolerance crop soil; extremely sensitive ESP crop (1355.09 Feddan), sensitive ESP crop (2845.73 Feddan) and moderately tolerant crop (84.88 Feddan). This edaphological soil classification enabled to calculate edaphological gypsum requirement (GR) for different ESP-tolerance crops. GIS-EC and ESP overlaid maps output the soil multivariable chemical classification. The overlaid GIS-EC-map classified the studied soils into five variants; non saline-non sodic soil (298.80 Feddan) moderately saline-non sodic soil (2701.42 Feddan), highly saline-non sodic soil (535.95 Feddan), moderately saline-sodic soil (424.04 Feddan), and highly saline-sodic soil (325.47 Feddan) Land suitability determined the main limitation factors to guide soil management and reclamation. Wheat soil suitability classified the soils into of the area was conditionally suitable (S4 =57.3%) and (S3 = 42.7%). As for faba bean, the soils had the three classes; marginally suitable (S3= 47.6%), conditionally suitable (S4 = 30.7%), and moderately suitable (S2 = 21.7%). Grape soil suitability map distributed into two main classes; 63.8% (moderately suitable = S2), 26.1 % (marginally suitable =S3). Soils majority was moderately suitable (S2 = 64.5 %) for olive tree. 61.79 % (moderately suitable = S2), 19.64 % (marginally suitable = S3), represented the majors of potato soils suitability. The largest area of the study area (88.02 %) was classified as highly (S1 = 40.5%) and moderately suitable (S2 = 47.5%) for tomato.

Gehan I. Kh.
Marei
The Defensive impact of geraniol (GeoH) against renal oxidative injury and nephrotoxicity induced by beta-cyfluthrin, (β-Cyf), fipronil(FPN). and their combined effects on the male rats were investigated. Eight categories, each category of male rats were used contain six rats. Category I as control, Category 2 GeOH (100 mg/kg bwt in corn oil). Categories 3, 4 and 5 rats have presented a single daily oral dose of (FPN) fipronil (4.85 mg/kg bwt), (β-Cyf ) beta-Cyfluthrin (19 mg/kg bwt)) and their combination. Categories 6, 7 and 8 rats have presented the same doses as Categories 3, 4 and 5 with GeOH (100 mg/kg) for 28 consecutive days, respectively. Rats which was exposed insecticides compared to control recorded significant decrease in body weight and rise in kidney weight. Treatment rats recorded significant renal function disruption by increase in uric acid and serum creatinine level. Also, insecticide-treated rats revealed renal oxidative damage was spotted in insecticide-treated rats through an increase in kidney lipid peroxidation (LPO) also, kidney appeared the decrease in antioxidant enzymes. Histopathological analysis of the kidney appeared that tubular destruction with multiple vacuolations, hyaline degeneration in glomeruli, and the thick arterial wall, and irregular glomerular lining in treated groups (FPN, β-Cyf, FPN + β-Cyf). In conclusion, the use of Geraniol (GeOH) seemed to be useful to rats, to a great extent by alleviation and decrease the damage sustained by insecticide exposure.

The present study was carried-out in three different locations in Alexandria city [El-Ebrahimeya zone (traffic area), El-Dekhela zone (industrial area) and Antoniadis Park (control area)] during two successive seasons 2015 and 2016. Homogeneous seedlings of Nerium oleander were planted individually in plastic pots (30 cm diameter) filled with mixture of sand and clay. 90 plants were planted in three locations in Alexandria city (30 plants each zone). Samples were collected during spring and autumn in both seasons. The obtained results showed the effect of different locations on vegetative growth of Nerium oleander plants. In both seasons, plants planted in Antoniadis Park had the highest leaves, stem and roots parameters in the first and second seasons, respectively. While, plants planted in El-Dekhela had the lowest vegetative growth rate in both seasons. The growth (leaves, stem and root) was also significantly affected by different periods during both seasons. Accordingly, it can be seen that the data were significantly increased gradually in the autumn, while, the lowest growth in the spring. The results of chemical analysis for plant parts showed the effect of different locations on lead, cadmium and zinc contents in plant parts. In both seasons, plants planted in El-Dekhela had the highest heavy metals content, while, those planted in Antoniadis Park had the lowest lead, cadmium and zinc contents in the first and second seasons, respectively. Chemical analysis of heavy metals content in plant parts was also significantly affected by different periods during both seasons. Accordingly, it can be seen from the data that heavy metals were significantly increased gradually in the spring, while, the lowest heavy metals content (lead, cadmium and zinc) in plant parts was found in autumn in the first and second seasons, respectively. Transfer factor (TF) indicates the efficiency of Nerium oleander plants to transfer metals from the soil to the plant parts. It can be seen that the transfer factor in the lead, cadmium and zinc content in Nerium oleander plants was increased steadily with different locations. We found that, plants in Antoniadis Park had the highest transfer factor with respect to the heavy metals content, while, those planted in El-Dekhela had the lowest transfer factor in the first season. On the other hand, the highest transfer factor in plant parts, was found in the stem for lead and cadmium, while it was in the leaves for zinc compared with different parts of plant.

Two field Experiments were conducted at km 48 Nubaria region, Alex. Cairo Desert Road, El- Behiera Government, Egypt, during 2016/2017 and 2017/ 2018 seasons, to study the effect of three humic acid levels and four boron fertilization rates on yield and quality of sugar beet (Beta vulgaris L.) cultivar monogerm (cv. Francisco). Treatments were arranged in a split- plot design in three replicates.The three humic acid levels (0= water, 3 and 6 kg/fed) at the form of (humat potasium 80% K2O) randomly assigned to the main plot. While, the four boron rates (0, 400, 800, and 1200 g/fed) were distributed at random within the sub plot at the form of Nutribor (8% Boric acid). Seeds were hand sown on 3rd and 5th October 2016/2017 and 2017/2018 seasons, respectively, in each (sub – plot), at the rate of 1 seed ball per hill on one side of the ridge at 20 cm apart. Root yield (ton/fed), top yield(ton/fed), biological yield(ton/fed), sugar yield (ton/fed), TSS%, sucrose%, purity %, extraction %, potassium %, α-amino nitrogen %, sodium %, and white sugar %, were determined in both seasons. The obtained results revealed that; 1). increasing humic acid rates from zero up to 6 kg /fed increased significantly root, biological, sugar yields ton/fed, TSS%, potassium percentage and white sugar percentage during 2016/2017 and 2017/2018 seasons. Where, the highest mean values were obtained by adding the higher level of humic acid (6 kg /fed). On the contrary, the lowest values were given by growing sugar beet plant under control treatment (zero kg/fed humic acid). On the other hand, increasing humic acid rates from zero up to 6 kg /fed decreased significantly extraction %, α-amino nitrogen %, sodium %, however, the lowest ones recorded with adding 6 kg/fed humic acid. Nevertheless, under this study, the highest mean values of these traits were obtained with control (zero kg/ fed humic acid) in both seasons, 2). increasing boron fertilization rates from zero to 400 g/fed, 800 g/fed and 1200 g/fed increased significantly the mean values of root yield, sugar yield, the total soluble solids (%), sucrose (%), purity (%), extraction (%) and white sugar (%).In addition, the highest mean values were recorded with application of 1200 g / fed, while the lowest mean values were obtained by growing sugar beet plant under the control treatment (zero boron= water) during the two seasons. On the contrast, increasing boron fertilization from zero up to 1200 g/fed decreased significantly potassium%, α- amino nitrogen (%), and sodium (%) in sugar beet root, meanwhile the lowest mean values were recorded when applying the rate of 1200 g/fed of boron fertilization. Whereas, the highest mean values were given under control treatment (zero g/fed) in the two seasons, 3). and the interaction between humic acid and boron fertilization affected significantly top yield ton/fed, biological yield ton/fed, the total soluble solids %, sucrose %, purity %, α- amino nitrogen% and sodium % during both seasons and sugar yield ton/fed during the first season 2016/2017. This showed that humic acid and boron fertilization act dependently on top yield, biological yield and sugar yield of sugar beet plant under this study.

Two field experiments were conducted during the summer seasons of 2016 and 2017 at the Experimental Station Farm; South El- Tahrir; Horticultural Research Station, El- Behiera Governorate. This investigation aimed to study the effect of bio- fertilizer potassien(Bacillus circulance)in combination with different rates of mineral potassium fertilizer (0,32,64 and 96kgK2O/fed) on the growth, yield and quality characters of potato CV. Spunta . Potassium fertilizer at 64 or 96 kgK2O/fed with application of bio-K fertilizer promoted growth of potato and the highest mean value of plant height, number of leaves plant-1, foliage fresh weight, leaves fresh weight, foliage dry weight, leaves dry weight , total chlorophyll and enhanced N, P and K uptake, as well as increased tuber weight ton/fed, average tuber weight and improved tubers quality characters expressed as dry matter, protein, starch, and total carbohydrates contents and specific gravity in the two seasons. It could be concluded that the interaction effect of inoculation potato tuber seeds with bio fertilizer at application of 67% (64 kg K2O/fed) of the recommended K level (96 kg K2O fed-1) increased the productivity of potato tuber and improved tuber quality characteristics, as the same as (96 kg K2Ofed-1). In addition to saving about 33% of potato requirement of K fertilizers and avoid environmental pollution hazards caused by excessive application of chemical fertilizers.

The objective of this paper was to study the effect of silicon dioxide (SiO2) and titanium dioxide (TiO2) nanoparticles NPs sprayed separate or in combination compare with traditional practices on plant ability to resist fungal diseases and improving growth and productivity of zucchini squash (Cucurbita pepo L.) crop in Al-Kantara Sharq experimental station located 30o 49' 41.4" N and 32o 24' 11.4" S, Eastern part of Al-Ismailia governorate within Sinai, Egypt during summer seasons of 2015 and 2016. The treatments were: 1.Control spraying with distilled water (T1), 2.Copper oxychloride Cu2(OH)3Cl at concentration of 5000 ppm (T2), 3.SiO2 25ppm (T3), 4.SiO2 50ppm (T4), 5.TiO2 25ppm (T5), 6.TiO2 50ppm (T6), 7.SiO2 25ppm + TiO2 25ppm (T7), 8.SiO2 25ppm + TiO2 50ppm (T8), 9.SiO2 50ppm + TiO2 25ppm (T9) and 10.SiO2 50ppm + TiO2 50ppm (T10). The results indicated that incidence and severity of powdery and downy moilew significantly decreased with SiO2 NPs whether sprayed at low or high concentration or if it was separate or in mixed with TiO2 NPs when compared with control (T1). Powdery mildew not response to individual sprayed TiO2 NPs but in opposite, incidence and severity of downy moilew significantly decreased with increasing TiO2 NPs concentration. up to 50 ppm compared with control. The obtained results revealed that foliar application with the tested materials include Cu2(OH)3Cl compared with control showed significant effect on all studied morphological growth characters, yield components and marketable yield as well as photosynthetic pigments and nitrogen, phosphorus and potassium (NPK) contents. Results refer that individual TiO2NPs whether in low or high concentration achieved superior promotion than SiO2 NPs on vegetative growth characters which expressed as shoot height, number of branches and leaves plant-1, largest leaf area, fresh and dry weight plant-1 and dry matter percentage, while the maximum values were attained from T10 compared with T1 and T2. Furthermore, no significant effects were recorded between T10, T8, T6, T5, T9 and T7 but there were achieved the highest values of fresh and dry fruit weight and fruit dry matter percentage when compared with control while the highest number of fruits were attained from all tested materials except, TiO2 NPs. Subsequently, control treatment and TiO2 NPs in low or high concentration whether individual or in combination with low concentration of SiO2 NPs significantly produced the highest heavy fruit weight per plant and plot while the lowest un-marketable fruit weights and number were achieved from foliar sprayed SiO2 NPs with their concentrations in addition to T10. For what it was no significant differences were found between T10, T2, T9, T8, T7, T4 and T3 treatments, there achieved the maximum production whether per plant, plot or feddan as well as marketable yield compared with control treatment. Spraying SiO2 NPs at concentration of 50 ppm achieved minimum un-marketable yield. Chemically, photosynthetic pigments, NO3-, P2O5-- and K+ contents significantly increased with all treatments compared with control while the highest accumulate in plant tissues were gotten from T10. Anatomically, results and photomicrograph indicated that thin epidermis layers surrounded malformed and destroyed palisade and spongy tissues as a result to fungal diseases infection were observed in untreated plants (control). On opposite, leaf thickness and upper and lower epidermis layers as well as space area (%) were increased when plants treated with separate or mixing at low or high concentration SiO2 and TiO2 NPs compared with control or cupper oxychloride. Also, of observation that TiO2 NPs increased photosynthetic cortical and exchangeable gas spaces more than SiO2 NPs which increased cell wall thickness. The maximum leaf thickness, palisade length, sponge length, upper epidermis thickness, lower epidermis thickness and area space (%) were attained from T10, T6, T8, T6, T6 and T6.

Abouelsaad
Two pots experiments, at two successive winter seasons, were carried out to investigate the effects of two nitrogen (N) sources (ammonium nitrate and urea) and foliar applications of molybdenum (Mo), sucrose (Suc) or selenium (Se) on the growth and quality of the edible parts of spinach (Spinacia oleracea L. cv. Balady). The results indicated that the growth and quality of spinach plants can be greatly determined by the applied N source. The edible parts of spinach plants that received urea as N source showed lower content of NO3-, soluble oxalate, insoluble oxalate and total oxalate plus higher level of P content, however, higher moisture content as well as lower accumulation of dry mass, vitamin C and Fe were also observed in both seasons. Among the tested foliar applications at different concentrations, the treatment with 10% sucrose showed superior effects for increasingspinach growth (increase fresh weight, dry weight and leaves area) and quality (increase the contents of N, P, K, Ca, Fe, total protein and chlorophyll, as well as decreasing the contents of soluble oxalate and total oxalate) relative to the control (distilled water)in both seasons. The interaction treatment of urea fertilizer with foliar application of 10% sucrose was the most efficient one in decreasing NO3- and soluble oxalate contents without reductions in growth (fresh and dry weights), the contents of vitamin C and minerals against the corresponding control in both seasons.

Effect of Glyphosate on Performance of Faba Bean Varieties Under Heavy Infestation of Orobanche crenata
Mahmoud M.
Zeid
Mona M.
Hemeid
Orobanche crenata is a devastating parasitic weed on faba bean with its effects not confined to the Mediterranean region anymore. This study investigated the effect of number of glyphosate sprays,at the rate of 86g a.i./ha, on the performance of a set of faba bean varieties varying in their resistance to the parasite under farmer’s field conditions. The main target was to find out whether faba bean resistance coupled with glyphosate application could be adopted as standard procedure for efficiently combating the parasite. Results indicated that, under current farmer’s field conditions, spraying resulted in a clear reduction in the number of emerged spikes from 18 to 49% and the amount of photo-assimilates accumulated by the parasite from 1 to 42%, depending on the variety and that was related to the number of sprays applied. There was no improvement in faba bean yield associated with the reduction in infestation under glyphosate sprays compared to the control, even with the most resistant faba bean varieties known in Egypt; namely Giza 843, Misr 1 and Misr 3. Considering its cost and impact on human health, glyphosate is not recommended for infested faba bean fields. In heavily infested fields, it is recommended to employ other integrated pest management protocols that aim at reducing the parasite seed bank per se before considering any winter pulses. This halt on winter pulses is essential to deplete the seed bank and prevent further spread of the parasite and should continue until a better technology to combat the parasite evolves. The new Misr 3 was seen here as a very promising variety that generally combines both good yield and low number of emerged spikes compared to older varieties Giza 843 and Misr 1.

The main aim of this investigation was to evaluate the meal of Egyptian chia seed (Salvia hispanica L.) as a source of bioactive componentscomparing with the USA imported one. The results showed slight differences in proximate composition, dietary fibers components, nutritional value, total and HPLC separated simple phenolic compounds especially, caffeic acid, gentisic, rosmarinic and cteachin between meals of local and imported chia seeds. Both meals had nearly similar amino acids pattern, in vitro protein digestibility (IVPD) (66.5 - 66.9%), computed- protein efficiency ratio (C-PER) (1.1 - 1.3) and biological value ( C-BV) ( 69.4 - 71.6% ) , high water ( 7.5-8.5 g water /g meal), oil ( 5.1-5.3 g oil / g meal) holding capacities, good emulsification capacity (52-55 ml oil/100 g), poor foaming capacity and stability, high total (55.8-57.7%), insoluble (48.2-53.3%) , neutral detergent (43-47.2%) and acid detergent (34.2-36%) dietary fibers. The antioxidant activity as determined by DPPH and ABTS methods was relatively higher in meal of the local than imported chia seeds. Dry fractionation of chia seed meal through 100 mesh sieve gave two fractions, one rich in protein (41.5- 45.5%) and others high in neutral detergent (86.5 - 90.7%), acid detergent (49.01-54%) and hemicellulose (36.7-37.49%) dietary fibers. Panelists accepted the physical and sensory properties of the biscuit products containing 5% of rich protein and high fiber chia seed meal fractions. Such results indicated the successful use of chia seeds meal as a source of bioactive ingredients in preparing functional food.

Gardenia jasminoides Ellis is an evergreen plant with fragrant creamy white flowers and glossy, darkgreen leaves, belongs to family Rubiaceae and member of the genus Gardenia. The current study aimed to afford a new technique for in vitro propagation and callus induction of G. jasminoides by using single nodes excised from soft cuttings using full strength MS salts supplemented with 30g/l sucrose, 4g/l gelrite and different concentrations of plant growth regulators. Generally, the current study showed that NAA and BA at 0.0 and 1.0 mg/l, respectively gave rise to the best results for initiation stage. Meanwhile, fortified the basal MS medium with BA and NAA at 2.0 and 0.250 mg/l, consecutively; resulted in the best results with respect to multiplication stage. Regarding rhizogenesis, the neoformed shoots produced from vegetative multiplication stage were rooted successfully upon cultured on MS medium supplemented with 1.0 mg/l IBA and NAA at either 0.250 or 0.500 mg/l, whereas the highest number of roots was recorded besides callus induction. Regarding embryonic callus induction, adding 2,4-D at 1.0 mg/l; enhanced embryonic callogenesis. Neoformed plantlets were acclimatized ex vitro and in vivo vigorously in mixture of perlite and peatmoss at (1:1, v/v), which resulted in the highest percentage value of survival / percent (100%) and successfully flowered and showed true-to-type plants ex vitro.

The Arab Republic of Egypt depends heavily on its agricultural sector. The majority of the agricultural population, directly or indirectly, depends on agriculture as their basic source of support, and agricultural exports from raw and manufactured commodities, constitute more than 70-80 of the Egyptian export earnings. The cultivated area , which was about 5.4 million feddans at the beginning of the last century has remained more or less static due to urbanization and is estimated now by about 7.0 million feddans. However, the Egyptian population has doubled almost six times in less than one century. ht has increased from 6.5 millions in 1882 to 104 millions in 2017 and the present rate of growth is about 2.5% The disparity between the rate of population growth and the growth of agricultural land resources, was reflected in the level of real per captia agricultural income which amounts to only 22.3 pounds according to 2010 statistics. Thus it has been the objective of this investigation to analyze the various constraints which hinder Egyptian agricultural economic development .
The contents of the study has been classified into four chapters. Chapter one deals with the research problem, chapter two deals with the review of previous literature and theoretical and analytical framework of the study. Chapter three deals with the determinants of horizontal and vertical agricultural development in Egypt, and chapter four deals with the economic and social constraints of agricultural economic development in Egypt.

Bawady
Ahmed Mohamed
Hanafy
Economic development is very important way to raising the national income, and increasing the economic standard of living in the country, Economic development is based on increase the production level in society. That is, the process of development are process that begins with the population and ends with them, and whereas women represent a half of the workforce in the society, so they cannot be excluded and marginalized. The research problem is represented by: The women's multiple jobs inside and outside its home, but not economically calculated, and thus the inability of society to reach the highest standard of living and productivity for a great part of the working forces of the state. The research aims to identify the women's jobs to increasing family income by using available agricultural resources: To identify their roles in various sectors, and determined the factors affecting these roles, according an aggregate variable determines women's different jobs, and search for its factors affecting, and determine how women desire to establish small businesses. Data sources: Primary data collected questionnaire by using sampling technique from the governorate, in addition to statistical secondary data published and unpublished by governmental agencies and institutions. Methodology: Descriptive and quantitative analysis, and simple and multiple regression, double logarithmic regression are used, To determine the factors affecting of the women's activities to development the economy of the new valley. The sampling study applied a 5% sampling fraction, the suitable sample size is about 297 units.
Statistical analysis results of the study: The participation of women in the economic development of new valley governorate is represented in five main fields. It is given that there is an overlap between them, from the correlation coefficients matrix, It has been shown that there is a high correlation between female participation in animal production and manufacturing, this is due to the fact that most of the female participation in manufacturing is based on animal products. The determinants of the contribution of women to economic activities include: It can be represented in according to order of importance as: Total wages for work in domestic activity of the year, own animals, the number of female children, the total number of work hours in the domestic activity of the year, the job status of women's, and finally woman's having a postal or bank account. Women's prefer to works in manufacturing, followed by agricultural work, then work by trading.
The most important problems facing women were: Lack of funding for small projects, there is not a suitable place for small businesses, they haven’t near markets, lack of training and guidance, they can't find production inputs, lack of experience in marketing, high prices of inputs, loans available are high interest, there is not refrigerators to save products, These problems represented between 80% and 10% of the women's point of view.
The women suggested same ways to solve these problems: Financing solutions: Providing loans and directing grants and subsidies for the expansion of microenterprises. And skills development solutions by intensifying training, providing animals care at low prices. Marketing solutions are, create outlets for permanent sale, encourage tourism to open up new markets, promotion of foreign exhibitions, and establish a unified craft area for women marketing.

A healthy person is a person who is better able to serve himself, his nation and society, The ill human who is afflicted by the disease sees him weak This undoubtedly has negative effects on the human, When the disease develops, a person becomes dependent on other people and cannot meet his various needs in life, The community is also affected by the presence of the disease among its members, where the productivity of these patients is weak.
housing in the Egyptian countryside is practiced in many of the productive activities of the family, from the production of bread to the Albanians and some small rural industries, which is distinguished from the urban housing, In addition to stable family relations, which called for the importance of the functional division of the spaces and internal units of the house as well as the materials used in construction, as all this affects the health of human.
Due to the random changes in the villages, new residential communities have emerged in the original villages as a result of the spread of the old settlements. Accordingly, the village population was divided according to the social situation and the instruction ....
In addition to the situation of deterioration and poor conditions and lack of facilities and services, and overcrowded housing and adhesion to each other, which led to poor health and environmental conditions sound.
Therefore, the main objective of this research Building system in Egyptian village and its relation to the spread of environmental diseases in the villages of Al-Nasser and Al-ghafr in the North of Tahrir area in Al-Beheira governorate.
The study data were collected using a questionnaire with a personal interview, which was collected through a random sample of 200 housing units.
A random sample of 30 units was taken to conduct a laboratory study on drinking water and stool analysis to identify the extent Pollution of drinking water and injury of individuals with parasites in light of the housing conditions of the studied sample.
The results showed that between each of the independent variables studied and the level of education for the husband and wife, Lighting, water problems, ventilation, hygiene and the associated variable of environmental diseases. It was found that There is a correlation relationship at confidence level (0.01)
There was also a significant correlation between the independent variables of age of husband and wife, level of education of males and the quality of agricultural activities, and the dependent variable at the potential level of 0.05.
The results showed that close proximity between the houses in the study areas, as (83.5%), which leads to the lack of quality ventilation, which is one of the most important requirements of the internal environment, it was revealed from the results that the equivalent (89.5%) of housing units in the study areas are not have Essential health services available in villages.

The shortage of animal and poultry feed resources is one of the main obstacles in the development of livestock and poultry wealth. This shortage will lead to an increase in the prices of animal feed and hence the cost of animal production and consequently increase the prices of animal, poultry and food products necessary to feed members of the society.
The main objective of the study is to study the animals need of the feed, the economies of their production and consumption in Egypt by studying the economic importance of animal, poultry production in Egypt. Indenting the animal needs of feed furthermore proposing ways to solve them.
The area of green fodder decreased by about 1.4% per year. This requires increasing the area of these feeds as well as horizontal agricultural expansion. The total quantity produced of green, dry and concentrated feeds decreased by 1.7% annually, therefore, the quantity currently produced should be increased otherwise the imported quantities of concentrated fodder will increase and the deficit in the agricultural trade balance will increase as well.
The value of animal and poultry production requirements in Egypt increased at a rate of about 10.8% per year, while livestock increased at a rate of about 0.5% annually, indicating the continuous increase in feed The available quantity of feed decreased by about 2.6% annually, while at the same time there was an increase in the quantity of surplus at an annual rate of 8.2%. This indicates that the issue of the green fodder crisis is not an issue. The explanation is that the problem lies in the way the animal takes these feeds in its diet.
It is expected to increase the importation of concentrated feeds at a rate of about 4.5% per year at least, to cover the deficit in the quantity produced. Also, increase the domestic production of these feed as imported concentrated feed is usually more expensive than their local counterparts. Customs tariff rate should be decreased on imported fodder as well as production requirements .

Two field experiments were conducted in the two locations (Marawaa and in El-wasiata) situated at 21° 24´ and 21° 39´ N ;32° 20`and 32° 47´ E and 508, 185m over sea altitude for the 2 situates, respectively, during 2014/2015 season to study the response of the six rows barley variety rehan sown by the rate 70 kgha-1 in lines 15cm apart to the nitrogen levels (0,50,100&150Kg N/ha-1) in the form of urea 46%.
The experiments were carried out in RCBD with 4 replicates, plat area was (25m2).
The Results revealed significant (P<0.01) effect on plant height in El-wasiata ,number of economic tillers and spike traits in both locations ,where the greatest incase resulted from 150Kg N/ha-1 compared to the control.
Biological yield was significantly (P<0.01) affected by N-levels, the least yield (3.65, 3.76 t/ha) due to control however the highest (4.11, 4.63 t/ha) resulted from 150Kg N/ha-1 application in the first and second locations, respectively.
Although there were increases in grain yield from 1.46, 1.51 t/ha due to non fertilization to 1.87, 1.96 t/ha due to 150Kg N/ ha application, but these differences did not reach the significance level in both location, .Straw yield exhibited significant (P<0.01) increases from ( 2.11, 2.24 t/ha) in control treatment to (2.4, 2.5 t/ha) at 150KgN/ha application .
Harvest index was not significantly affected by N-levels in both sites, while 1000 – grain weight affected significantly (P<0.01)where the least values (35.86, 35.20g) due to 50Kg N/ha-1 and zero comparing to the highest (39.20, 37.40g) resulted from 150Kg N/ha in both Marawaa and El-wasiata, respectively.
